`17:02.34`	`[g2-lap]`	`looks like it`
`17:04.04`	`vmaster`	`yeah`
`17:04.46`	`vmaster`	`i've quite a lot of fixes in my local tree, but they all depend on each other, and i'm always just fixing "that one last bit"`
`17:08.05`	`[g2-lap]`	`developing a community isn't always easy`
`17:08.32`	`[g2-lap]`	`I'm glad the openjtag community is coming along, but it's a long time in the making`
`17:08.50`	`[g2-lap]`	`some things like the nslu2 or ep93xx are just a lot easier to get interest`

`18:05.40`	`vmaster`	`there are some example configs in the ./doc/configs/ folder`
`18:05.53`	`[g2-lap]`	`where do they go ?`
`18:06.03`	`vmaster`	`either rename one to openocd.cfg (default), or specify the name with '-f config.file'`
`18:06.15`	`vmaster`	`all cwd at the moment`
`18:06.33`	`vmaster`	`or an absolute path, of course`
`18:06.50`	`[g2-lap]`	`does the device really need to be there ?`
`18:07.33`	`vmaster`	`yes`
`18:07.50`	`[g2-lap]`	`that might be an issue :) as I've have now`
`18:07.56`	`[g2-lap]`	`s/now/none/`
`18:08.28`	`[g2-lap]`	`vmaster I would humbly suggest having a default memory device/test adapter`
`18:08.40`	`vmaster`	`hm?`
`18:09.03`	`[g2-lap]`	`then ppl could verify the program operation and connectivity of the tool chain and the jtag device separately`
`18:09.16`	`[g2-lap]`	`and also play around with the tool`
`18:09.29`	`[g2-lap]`	`does that make sense ?`
`18:09.56`	`vmaster`	`mhh, not to me, but that might be because i'm biased - i've designed it that way because i thought people would use it that way`
`18:10.25`	`[g2-lap]`	`sure I think that makes sense`
`18:10.52`	`vmaster`	`it's a daemon process that continously talks to the target`
`18:11.04`	`[g2-lap]`	`however I'm talking about bringing new users into the ocd fold, or allowing ppl to evaluate the sw`
`18:11.31`	`[g2-lap]`	`right and the daemon can talk to a "fake" device in memory"`
`18:11.49`	`vmaster`	`ah, ok`
`18:11.52`	`[g2-lap]`	`a pretend ARM7, ARM9, your device`
`18:12.20`	`[g2-lap]`	`then the boot it all up, check out the scan chain, detect, etc...`
`18:12.30`	`[g2-lap]`	`maybe even step and breakpoint`
`18:12.58`	`[g2-lap]`	`it _might_ even make sense to interface to QEMU running in emulation`
`18:13.39`	`[g2-lap]`	`then you could O`
`18:13.43`	`[g2-lap]`	`oops..`
`18:14.12`	`[g2-lap]`	`then you could OCD debug QEMU system apps`
`18:14.38`	`vmaster`	`yeah, that would indeed be very nice`
`18:14.41`	`[g2-lap]`	`but it's really a side show`
`18:14.46`	`vmaster`	`yep`
`18:15.02`	`[g2-lap]`	`the point being many new users will want to play and learn the sw`
`18:15.06`	`[g2-lap]`	`and experiment with it`
`18:15.26`	`[g2-lap]`	`and IMHO they shouldn't need a jtag device and hw to do that`
`18:15.44`	`[g2-lap]`	`clearly if the like it they'll be heading that way`
`18:16.10`	`[g2-lap]`	`but 80% (or at least 50%) will be non target specific`
`18:16.24`	`[g2-lap]`	`and you can have testers debug and fix those without devices`
`18:16.37`	`[g2-lap]`	`does that make much sense ?`
`18:16.45`	`[g2-lap]`	`do you agree ?`
`18:16.55`	`[g2-lap]`	`or is [g2-lap] full of it ?`
`18:17.39`	`vmaster`	`well, yeah, it would be nice, but it sounds like a lot of work for a "sideshow"`
`18:18.19`	`vmaster`	`and most problems are very hardware related`
`18:18.30`	`vmaster`	`so testers wouldn't gain much from testing an emulated target`
`18:18.47`	`vmaster`	`unless the emulator simulates all the nasty details of all the different uCs (not only cores)`
`18:19.08`	`[g2-lap]`	`it's not to simulate all that stuff`
`18:19.19`	`[g2-lap]`	`it's to enable debugging the tool`
`18:19.41`	`[g2-lap]`	`i.e. here I sit all ready to go`
`18:19.55`	`vmaster`	`yeah, but to debug the tools you'd have to simulate a lot of details of the target system`
`18:19.55`	`[g2-lap]`	`I can't hookup gdb to ocd`
`18:20.29`	`[g2-lap]`	`ok it was just a sugggestiong`
`18:20.53`	`[g2-lap]`	`however, I'm left in the situation of the following regarding OCD now`
`18:21.07`	`[g2-lap]`	`1) get an adapter and wait for it to arrive`
`18:21.22`	`[g2-lap]`	`or 2) work on something else`
`18:22.13`	`[g2-lap]`	`ok 3) I'll look at the OCD implementation and figure out how to do and ep93xx adapter`
`18:22.25`	`[g2-lap]`	`but that's not the normal case`
`18:22.37`	`vmaster`	`do you have any parallel port download cable?`
`18:22.43`	`vmaster`	`xilinx, lattice, whatever`
`18:23.02`	`[g2-lap]`	`I have a couple of those, but no parallel on the ARM boards where I'm running this`
`18:23.31`	`[g2-lap]`	`the ep93xx is ready to run JTAG at 8Mhz via bit-banging`
`18:23.51`	`[g2-lap]`	`OCD is compiled for it`
`18:24.07`	`vmaster`	`oh, so you compiled openocd to run on the ep93xx?`
`18:24.15`	`[g2-lap]`	`:)`
`18:24.39`	`[g2-lap]`	`I compiled it in an ARM chroot`
`18:24.45`	`vmaster`	`ok`
`18:24.55`	`[g2-lap]`	`it was actually compiled on the Loft as that's a lot faster`
`18:25.13`	`[g2-lap]`	`but I built 99% of beewoolies JTAG adapter on the ep93xx`
`18:25.22`	`[g2-lap]`	`ok 70%`
`18:25.31`	`[g2-lap]`	`then I switch to the faster box`
`18:26.02`	`[g2-lap]`	`so I could reboot into the ep93xx on that external drive with ocd compiled and ready to urn`
`18:26.12`	`[g2-lap]`	`burn/run`
`18:26.31`	`[g2-lap]`	`we are but a driver away`
`18:27.05`	`[g2-lap]`	`then depending on size we'd add it to OE and have a flash built ssh+ocd rootfs`
`18:27.51`	`vmaster`	`ok, at least i understand why you'd want a simulated target to start with`
`18:30.20`	`vmaster`	`but most people aren't looking to port openocd to their own jtag platform, but rather want to debug the target they already have`
`18:31.00`	`[g2-lap]`	`sure`
`18:31.22`	`[g2-lap]`	`but lets talk about where we go from here`
`18:31.32`	`[g2-lap]`	`with the ep93xx platform`
`18:32.17`	`[g2-lap]`	`I'd imagine that all of this would port the the geep (except for may the Port assignments) which are most likely trivial`
`18:32.33`	`[g2-lap]`	`AchiestDragon thoughts on the last comment ?`
`18:33.15`	`[g2-lap]`	`I've got OCD compiled for the 93xx but no driver GPIO driver yet`
`18:33.22`	`[g2-lap]`	`the FPGA only makes it better`
`18:33.30`	`[g2-lap]`	`which would be new work`
`18:33.48`	`vmaster`	`porting it to something using gpio would only require something similar to src/jtag/parport.c`
`18:34.29`	`[g2-lap]`	`vmaster well we can run really fast as lennert found out yesterday`
`18:34.44`	`vmaster`	`yeah, saw that`
`18:35.03`	`[g2-lap]`	`so now we are in the area of general design versus performance`
`18:35.16`	`[g2-lap]`	`it's a little like usability and security`
`18:35.23`	`AchiestDragon`	`hmm`
`18:40.15`	`AchiestDragon`	`the ep9302 has gpio the geep without the jtag board could use its onboard fpga to bit bang as fast as with it but the buffer would be limited to using the 64mb video ram`
`18:41.58`	`[g2-lap]`	`AchiestDragon from what I know about the geep it'll do a lot of things`
`18:42.33`	`[g2-lap]`	`regarding JTAG to 5-8Mhz rates we may be able to get there directly with a 9302 and DIOs`
`18:42.50`	`AchiestDragon`	`yes`
`18:43.02`	`[g2-lap]`	`so that's basicall $65 from Glomation in 100 piece quantity`
`18:45.10`	`vmaster`	`ah, i looked at the ep's SSP today. it would be flexible enough to do JTAG, but it's maximum frequency is ~3.5mhz, so that's no use, if it can bitbang faster than that`
`18:46.27`	`[g2-lap]`	`I think lennert was bangning at nearly 15+Mhz yesterday for nearly an effective 8Mhz TCLK rate`
`18:47.44`	`[g2-lap]`	`we don't have to run that fast to start, but we could run at 800K and handle all the normal stuff like chip detect, scan etc`
`18:47.48`	`[g2-lap]`	`then just crank the rate`
`18:48.08`	`[g2-lap]`	`it should be about as easy as it gets`
`18:54.55`	`[g2-lap]`	`lennert ping`
`18:56.56`	`[g2-lap]`	`lennert vmaster I suggest for now lennert and I just put a big #ifdef around the whole parport.c code and insert the ep93xx GPIO output routines for outb`
`18:57.08`	`[g2-lap]`	`and set jtag_speed=0`
`18:58.05`	`[g2-lap]`	`sound sane or silly ?`
`18:59.16`	`[g2-lap]`	`vmaster and we'd need and arm9_par ?`
`18:59.22`	`[g2-lap]`	`or arm9_wiggler ?`
`18:59.47`	`vmaster`	`arm9_wiggler`
`19:00.06`	`[g2-lap]`	`then one glomation ts72xx could openocd another`
`19:00.08`	`vmaster`	`is a config example for arm9tdmi targets using a paralell port wiggler`
`19:00.10`	`vmaster`	`yep`
`19:00.31`	`[g2-lap]`	`I think I've got 4 boards`
`19:00.47`	`[g2-lap]`	`two 7200s, a glomation, and a cirrus`
`19:01.19`	`[g2-lap]`	`vmaster are there any really cheap arm7s out there ?`
`19:02.17`	`[g2-lap]`	`and it'll take vmaster about 5 seconds to the the arm9_wiggler conf right ?`
`19:02.54`	`vmaster`	`the philips lpc boards from olimex are quite cheap`
`19:03.38`	`vmaster`	`about $50 for the smallest one`
`19:03.41`	`[g2-lap]`	`sparkfun sells those right ?`
`19:04.11`	`vmaster`	`yeah`
`19:07.28`	`vmaster`	`that one should be enough: http://www.sparkfun.com/commerce/product_info.php?products_id=667`
`19:07.31`	`vmaster`	`$30`
`19:09.22`	`vmaster`	`not sure if you can actually buy one though... lpc2103 is hard to get`
`19:09.51`	`[g2-lap]`	`well I probably don't _need_ it`
`19:10.06`	`[g2-lap]`	`<PROTECTED>`
`19:10.12`	`[g2-lap]`	`but it would be fun`
`19:10.34`	`[g2-lap]`	`not nearly as much fun as making ocd/taproot run on ep93xx though :)`
`19:11.37`	`vmaster`	`if you just want to have a look at the openocd's command line interface telnet to mmd.ath.cx:4444`
`19:12.01`	`vmaster`	`a philips lpc2294 connected with a ftdi ft2232 jtag interface, running a blinking led example`
`19:14.21`	`[g2-lap]`	`vmaster I'd like to get it running on the ep93xx then I'll play with it :)`
`19:14.42`	`vmaster`	`heh, ok`
`19:14.43`	`[g2-lap]`	`lennert saw your talk at fosdem and said it sounded interesting`
`19:14.52`	`[g2-lap]`	`that's plenty good enough for me`
`19:15.10`	`[g2-lap]`	`so there are 9 lines you use in the parallel port`
`19:15.27`	`vmaster`	`no`
`19:15.35`	`vmaster`	`6 lines`
`19:15.45`	`vmaster`	`TDI, TDO, TMS, TCK, nTRST and nSRST`
`19:15.55`	`[g2-lap]`	`<PROTECTED>`
`19:16.07`	`[g2-lap]`	`tdo trst tms tck tdi srst o_inv i_inv init */`
`19:16.13`	`vmaster`	`the other three elements of the cable structure define the polarity (output invert, input invert) and the initial value the port should be set to (init)`
`19:16.34`	`[g2-lap]`	`Ok so we are good to go with 1 byte`
`19:16.42`	`vmaster`	`yeah`
`19:17.02`	`vmaster`	`parport.c provides an amount of flexibility you don't need with the ep93xx, where you define what the lines are`
`19:17.50`	`[g2-lap]`	`right. I was gonna ifdef the original code out and just rewrite the rest for the ep93xx trying to keep the functions the same`
`19:18.29`	`vmaster`	`i'll give you a blank ep93xx.c where you just have to fill in three functions`
`19:18.54`	`vmaster`	`read (tdo) write (tdi, tms, tck) and reset (trst, srst)`
`19:19.31`	`vmaster`	`well, and the init stuff (if that's necessary for how you access the gpio's on the ep93xx)`
`19:19.56`	`[g2-lap]`	`well I think I'd inline assember those functions in that routine`
`19:20.24`	`[g2-lap]`	`maybe not`
`19:20.31`	`[g2-lap]`	`it'll just be one statement`
`19:22.16`	`[g2-lap]`	`vmaster lemme see if i've got this right`
`19:22.39`	`[g2-lap]`	`the ep93xx.c would be used instead of the parport.c right ?`
`19:23.16`	`[g2-lap]`	`then we'd have a arm9_ep93xx.cnf`
`19:23.51`	`vmaster`	`yes`
`19:23.58`	`vmaster`	`all the logic is in bitbang.c`
`19:24.14`	`vmaster`	`which just calls read, write and reset to toggle the lines`
`19:29.28`	`vmaster`	`http://mmd.ath.cx/ep93xx.c`
`19:30.31`	`vmaster`	`this has to be included in jtag.c where all the other interfaces are IFDEFed, and then added to the autotools stuff`
`19:38.50`	`[g2-lap]`	`vmaster THX`
`19:42.08`	`[g2-lap]`	`ok so #if BUILD_EP93XX == 1 define the extern and`
`19:43.03`	`[g2-lap]`	`#if BUILD_EP93XX == 1 include the routine`
`19:43.12`	`[g2-lap]`	`those two places`
`19:43.22`	`[g2-lap]`	`plus the autotools stuff`
`19:44.45`	`vmaster`	`yeah`
`19:45.11`	`vmaster`	`"include the routine" would be &ep93xx_interface`
`19:47.24`	`[g2-lap]`	`nod :)`
`19:47.43`	`lennert`	`sorry, back`
`19:49.57`	`lennert`	`doing the ep93xx gpio bits is really easy, i can do that`
`19:51.50`	`[g2-lap]`	`cool`
`19:54.14`	`lennert`	`[g2-lap]: how do you want to hook up the GPIOs?`
`19:54.37`	`lennert`	`all on port A?`
`19:54.52`	`[g2-lap]`	`lennert can you look at port C ?`
`19:54.59`	`lennert`	`sure`
`19:55.01`	`[g2-lap]`	`I'm not sure where port A comes out`
`19:55.11`	`[g2-lap]`	`ports C and D come out on the keyboard header`
`19:55.13`	`lennert`	`ok, and what bit assignment?`
`19:55.26`	`lennert`	`do you have a multimeter?`
`19:55.31`	`[g2-lap]`	`for now I don't think it matters`
`19:55.37`	`[g2-lap]`	`yeah a cheap one`
`19:55.38`	`lennert`	`ok, i'll pick something`
`19:55.46`	`[g2-lap]`	`I've got flying leads`
`19:56.04`	`[g2-lap]`	`so I can just arrange them`
`19:56.06`	`lennert`	`0:TDO 1:TDI 2:TCK 3:TMS 4:TRST 5:SRST`
`19:56.21`	`[g2-lap]`	`actually we should look at the header`
`19:56.33`	`lennert`	`ok, can you do that bit?`
`19:56.35`	`[g2-lap]`	`I've got the 6 pin connectors from digilent`
`19:56.38`	`lennert`	`then i'll write the code now`
`19:56.44`	`lennert`	`already half done in fact`
`19:56.45`	`[g2-lap]`	`sure`
`19:57.39`	`lennert`	`vmaster: what do i return on error? ERROR_ERROR? :)`
`19:58.22`	`vmaster`	`heh :P`
`19:58.37`	`vmaster`	`ERROR_OK`
`19:58.46`	`vmaster`	`but that's not checked in most cases anyway ;)`
`19:58.47`	`lennert`	`ERROR_OK = everything is fine`
`19:58.50`	`lennert`	`what if the init failed?`
`19:59.01`	`lennert`	`or no?`
`19:59.02`	`vmaster`	`ERROR_JTAG_INIT_FAILED`
`19:59.06`	`lennert`	`thanks`
`20:00.02`	`lennert`	`vmaster: should i drive TDI/TCK/TMS/TRST/SRST to any particular value in init()?`
`20:00.29`	`vmaster`	`TDI and TCK low, TMS, TRST and SRST high`
`20:00.35`	`lennert`	`thanks`
`20:00.57`	`vmaster`	`it's not strictly necessary, but that's how i initialize the parport interfaces`
`20:01.12`	`vmaster`	`well, driving the resets high is necessary`
`20:01.22`	`vmaster`	`you should initialize the output_value with that`
`20:01.39`	`vmaster`	`if you're using it at all`
`20:01.44`	`lennert`	`yeah`
`20:01.47`	`[g2-lap]`	`lennert we can change the pin assignment later`
`20:01.51`	`lennert`	`there's no atomic 'make high' or 'make low' register`
`20:02.14`	`vmaster`	`ah, ok`
`20:02.18`	`[g2-lap]`	`I'll have to buzz some cables`
`20:02.23`	`lennert`	`so i have to write all the bits every time`
`20:02.57`	`[g2-lap]`	`lennert we can read modify write`
`20:03.11`	`lennert`	`[g2-lap]: no need, we keep a local u8 with the mask we last wrote`
`20:03.21`	`lennert`	`rmw is too slow`
`20:03.27`	`vmaster`	`yeah, that's how it's done for the parport, too`
`20:04.14`	`[g2-lap]`	`lennert not if you inline assembler`
`20:06.03`	`lennert`	`http://www.wantstofly.org/~buytenh/ep93xx/ep93xx-openocd-jtag.diff`
`20:06.09`	`lennert`	`it probably won't even compile, but you get the idea`
`20:06.11`	`[g2-lap]`	`but we can look at the optimzation stuff in detail later`
`20:06.13`	`lennert`	`this assumes gpio port A`
`20:06.21`	`lennert`	`for gpio port C/D i have to change two offsets`
`20:06.34`	`[g2-lap]`	`lennert lets start with C`
`20:06.35`	`lennert`	`it just mmaps /dev/mem like my test code`
`20:06.39`	`lennert`	`C is fine too`
`20:06.41`	`[g2-lap]`	`"ROW..."`
`20:06.57`	`[g2-lap]`	`unless you are gonna test on the TS7200`
`20:07.16`	`[g2-lap]`	`actually it should be A or B for the TS and C for the glomation for now`
`20:07.26`	`lennert`	`i'll make it configurable`
`20:07.39`	`[g2-lap]`	`unless port A is brought out on the glomation somewhere`
`20:07.50`	`[g2-lap]`	`I found C/D but not A yet`
`20:08.33`	`[g2-lap]`	`and we've got to be configured properly for GPIO not keboard in the syscfg reg or whatever it's called`
`20:08.37`	`[g2-lap]`	`I'm sure lennert knows`
`20:10.20`	`lennert`	`http://www.wantstofly.org/~buytenh/ep93xx/ep93xx-openocd-jtag.diff`
`20:10.22`	`lennert`	`new version up`
`20:10.26`	`lennert`	`with configurable gpio port a/b/c/d`
`20:10.33`	`lennert`	`didn't do the sysconf bits yet`
`20:11.49`	`lennert`	`how does it look?`
`20:13.02`	`lennert`	`[g2-lap]: i don't think gpio bank C shares pins with anything?`
`20:13.14`	`lennert`	`[g2-lap]: at least, can't find any relevant bits in the DeviceCfg register`
`20:13.46`	`lennert`	`anyway, let me know if this works`
`20:14.28`	`[g2-lap]`	`lennert C and D share with the keyboard`
`20:15.11`	`[g2-lap]`	`page 762 of the cirrus logic 9312 doc`
`20:15.56`	`lennert`	`ah`
`20:16.02`	`[g2-lap]`	`I guess the default function is row/col`
`20:16.03`	`lennert`	`hmmmmm`
`20:16.18`	`lennert`	`so we need to configure GonK mode`
`20:16.30`	`lennert`	`hmmo k`
`20:16.37`	`lennert`	`you can't find port a/b anywhere?`
`20:16.45`	`[g2-lap]`	`I can look`
`20:17.17`	`lennert`	`setting GonK is enabling bit 27 in DeviceCfg`
`20:17.45`	`lennert`	`ok`
`20:17.47`	`lennert`	`that is unsafe, actually`
`20:17.54`	`lennert`	`kernelspace is writing to that register too`
`20:18.07`	`lennert`	`anyway, we can hope it goes ok`
`20:18.09`	`lennert`	`i'll code it up`
`20:18.20`	`[g2-lap]`	`lennert hold on for a minute`
`20:18.43`	`[g2-lap]`	`I can look for a couple minutes if A or B comes out`
`20:18.48`	`lennert`	`ok`
`20:18.51`	`lennert`	`that would be better`
`20:18.56`	`lennert`	`it'd be compatible with the ts72xx too`
`20:18.56`	`[g2-lap]`	`ideally they'd be nice as A/B come out on the 9302`
`20:19.01`	`lennert`	`yeah`
`20:19.07`	`lennert`	`not sure whether 9302 has c/d`
`20:19.13`	`[g2-lap]`	`then we'd just have 1 or 2 configs`
`20:19.22`	`[g2-lap]`	`if the pinouts are different between ts and glo`
`20:22.41`	`lennert`	`ok, implemented`
`20:23.03`	`lennert`	`we have a function, set_gonk_mode(), that enables G-on-K`
`20:25.38`	`[g2-lap]`	`lennert we're gonna have to go with that as A/B are not brought out on the 12`
`20:25.44`	`[g2-lap]`	`9312 that is`
`20:29.01`	`*** join/#openjtag koen (i=koen@dominion.kabel.utwente.nl)`
`20:29.11`	`lennert`	`ok`
`20:29.13`	`[g2-lap]`	`cool`
`20:29.21`	`lennert`	`this module just hardcodes port C and forces GonKL to be on`
`20:29.26`	`lennert`	`that should really be a config option`
`20:29.29`	`[g2-lap]`	`koen thx for stopping by`
`20:29.43`	`[g2-lap]`	`lennert that's fine for now`
`20:29.45`	`koen`	`[g2-lap]: http://ewi546.ewi.utwente.nl/tmp/viewmtn/revision.psp?id=bae20f6f5bee8712c32266160866a282d7948bf4`
`20:29.56`	`lennert`	`he packaged openocd for OE`
`20:30.18`	`[g2-lap]`	`koen I'll pull and test later`
`20:30.33`	`[g2-lap]`	`there are two things to test now`
`20:30.41`	`lennert`	`1) does it compile`
`20:31.10`	`[g2-lap]`	`lennert I've got everything build except our changes already`
`20:31.32`	`lennert`	`our change is what i wonder about`
`20:31.45`	`[g2-lap]`	`so 1) is testing the changes so we can give them to vmaster for "upstream"`
`20:31.51`	`lennert`	`yup`
`20:32.07`	`[g2-lap]`	`then 2) is roll that into OE`
`20:32.15`	`lennert`	`that should happen automatically`
`20:32.27`	`[g2-lap]`	`right on the next pull and there's little config issues`
`20:32.38`	`vmaster`	`currently openocd expects to have everything in a local filesystem, including binaries you want to upload to the target`
`20:32.52`	`vmaster`	`that might have to be changed when running openocd on a sbc like the ts7200`
`20:33.08`	`vmaster`	`or you require nfs`
`20:33.11`	`[g2-lap]`	`right as we've got a 5MB jffs2`
`20:33.33`	`[g2-lap]`	`we can run in a chroot to`
`20:33.56`	`koen`	`72K ../../../../deploy/ipk/openocd_svn-r0_armv5te.ipk`
`20:34.06`	`lennert`	`ok, let me know when you've tested the ep93xx module`
`20:34.29`	`[g2-lap]`	`lennert let's get all the changes together`
`20:34.47`	`lennert`	`?`
`20:34.49`	`[g2-lap]`	`I've got jtag.c modified`
`20:35.01`	`[g2-lap]`	`and I can pull your ep93xx.c`
`20:35.05`	`lennert`	`ok`
`20:35.10`	`lennert`	`you need vmaster's ep93xx first`
`20:35.13`	`lennert`	`mine is just a diff`
`20:35.18`	`[g2-lap]`	`ok I've got his`
`20:35.22`	`lennert`	`ok`
`20:42.59`	`[g2-lap]`	`vmaster so do modify the Makefile.am or .in ?`
`20:43.52`	`[g2-lap]`	`lennert koen feel free to jump in`
`20:44.10`	`[g2-lap]`	`I've got the ep93xx patches and the jtag.c updated`
`20:44.27`	`[g2-lap]`	`I just need to correct the automake and then configure and build`
`20:44.44`	`[g2-lap]`	`but I don't know whether to modify the .in or .am`
`20:45.24`	`koen`	`iirc the .in`
`20:47.09`	`[g2-lap]`	`doh I'm modifing the am`
`20:47.35`	`[g2-lap]`	`which it think may be correct as it's got the earlier timestamp`
`20:47.58`	`lennert`	`the .am makes the .in, and the .in makes the configure, no?`
`20:48.16`	`lennert`	`hmmm.. ignore that, i don't know what i'm talking about :)`
`20:48.22`	`koen`	`don't forget about configure.ac ;)`
`20:49.34`	`[g2-lap]`	`koen you mean like this ?`
`20:49.37`	`[g2-lap]`	`./bootstrap`
`20:49.37`	`[g2-lap]`	`src/jtag/Makefile.am:42: EP93XX does not appear in AM_CONDITIONAL`
`20:49.39`	`[g2-lap]`	`:)`
`20:50.24`	`[g2-lap]`	`I don't think there's a .ac`
`20:50.29`	`lennert`	`(btw, it won't really compile unless you add sys/mman.h and unistd.h i think)`
`20:50.33`	`[g2-lap]`	`we run ./bootstrap then ./configure`
`20:50.55`	`[g2-lap]`	`lennert trust but verify :)`
`20:52.01`	`lennert`	`[g2-lap]: i didn't have a copy of openocd to work from :P`
`20:54.41`	`vmaster`	`in src/jtag/Makefile.am, add a block like "if FTD2XX ..."`
`20:55.18`	`vmaster`	`and add $(EP93XXFILES) to the libjtag_a_SOURCES line`
`20:55.58`	`vmaster`	`then modify configure.in`
`20:56.20`	`vmaster`	`just duplicate something like the ftd2xx part`
`20:58.40`	`[g2-lap]`	`vmaster I think I've got it`
`20:58.56`	`[g2-lap]`	`I'm just hammering the build_ep93xx=yes at the top level`
`20:59.09`	`[g2-lap]`	`but other than the conditional and the code actually compiling it's working`
`20:59.26`	`[g2-lap]`	`now we'll sort out the compile issues`
`21:00.07`	`lennert`	`actually, i can do that`
`21:00.10`	`[g2-lap]`	`http://pastebin.ca/44819`
`21:00.15`	`lennert`	`most of the things i wanted to do today i didn't get done anyway`
`21:00.19`	`[g2-lap]`	`cause I know you guys are _dying_`
`21:00.25`	`[g2-lap]`	`heh`
`21:00.33`	`[g2-lap]`	`ok so sys/....`
`21:00.33`	`lennert`	`looks very good actually`
`21:00.36`	`lennert`	`you need sys/mman.h`
`21:00.42`	`lennert`	`unistd.h i suppose`
`21:00.57`	`lennert`	`can you try again then?`
`21:02.23`	`[g2-lap]`	`houston slight problem`
`21:02.37`	`[g2-lap]`	`the include path for the 93xx stuff`
`21:03.09`	`lennert`	`?`
`21:03.28`	`[g2-lap]`	`strike that`
`21:03.39`	`[g2-lap]`	`it's the normal kernel headers`
`21:04.41`	`lennert`	`okay`
`21:07.03`	`[g2-lap]`	`do I want kernel-package ?`
`21:07.24`	`[g2-lap]`	`basically my choort doesn't have the kernel development stuff`
`21:07.39`	`[g2-lap]`	`s/choort/chroot/`
`21:07.58`	`[g2-lap]`	`I've got the linux-kernel-headers installed`
`21:14.48`	`[g2-lap]`	`gcc -DHAVE_CONFIG_H -I. -I. -I../.. -I../../src/helper -g -O2 -c ep93xx.c`

`21:15.24`	`lennert`	`(i.e. add "#include <fcntl.h>" somewhere`
`21:16.58`	`[g2-lap]`	`ok jtag compiles and links`
`21:17.14`	`[g2-lap]`	`I think we are just missing the arm9_ep93xx config`
`21:18.04`	`vmaster`	`take the arm9_ftd2xx.cfg, replace 'interface ftd2xx' with 'interface ep93xx' and you're done`
`21:18.05`	`[g2-lap]`	`vmaster ?`
`21:18.06`	`lennert`	`whee, it builds`
`21:18.11`	`lennert`	`hehe`
`21:18.12`	`[g2-lap]`	`whee`
`21:18.19`	`lennert`	`an answer almost even before you ask the question ;)`
`21:18.24`	`[g2-lap]`	`ok`
`21:23.08`	`[g2-lap]`	`and boots there`
`21:24.29`	`[g2-lap]`	`Um.... you know I could run this on the 9302 TS too`
`21:25.06`	`lennert`	`you'd have to change the code to use bank A though`
`21:25.11`	`lennert`	`and then use the 'LCD' connector on the board`
`21:26.56`	`lennert`	`the rightmost 4 rows of 2 pins (i.e. the pins closest to the backplane) are EGPIO0..7 (which are on bank A)`
`21:28.30`	`koen`	`how much faster would this ep93xx jtag be compared to a parallel port 'wiggler'?`
`21:28.48`	`vmaster`	`a wiggler achieves ~350kHz`
`21:29.04`	`vmaster`	`that ep93xx jtag could probably achieve 5 MHz, maybe more`
`21:29.12`	`[g2-lap]`	`vmaster that's a TCLK rate right ?`
`21:29.16`	`vmaster`	`yes`

`21:29.37`	`[g2-lap]`	`heh`
`21:29.39`	`lennert`	`[g2-lap]: or set /dev/mem so that you can access it`
`21:29.46`	`lennert`	`[g2-lap]: sorry, that's the only way to access the gpio controller`
`21:30.13`	`vmaster`	`this is another problem`
`21:30.28`	`[g2-lap]`	`yeah as confirmed :)`
`21:30.47`	`lennert`	`you could use parport if you didn't care about speed`
`21:30.54`	`lennert`	`i.e. the kernel parport stuff`
`21:30.58`	`lennert`	`same for the GPIOs`
`21:33.01`	`vmaster`	`[g2-lap]: can you send me a tarball of your sources? that would save me from modifying the auto stuff myself ;)`
`21:36.52`	`[g2-lap]`	`vmaster sure`
`21:37.02`	`[g2-lap]`	`actually I can send you a diff`
`21:37.13`	`[g2-lap]`	`from r47`
`21:38.58`	`vmaster`	`that would be nice`
`21:40.36`	`[g2-lap]`	`vmaster http://pastebin.ca/44830`
`21:40.49`	`[g2-lap]`	`that plus the ep93xx.c`
`21:41.00`	`[g2-lap]`	`and the .cfg`
`21:41.08`	`NAiL`	`hmm... what's the openocd stuff?`
`21:41.24`	`[g2-lap]`	`vmaster's project`

`21:41.40`	`vmaster`	`[g2-lap]: + &_ep93xx_interface,`
`21:41.42`	`lennert`	`[g2-lap]: so does it work?`
`21:42.02`	`[g2-lap]`	`vmaster ah _`
`21:42.04`	`vmaster`	`the first underscore shouldn't be there`
`21:42.05`	`vmaster`	`yeah`
`21:42.10`	`[g2-lap]`	`ok`
`21:46.45`	`[g2-lap]`	`Ok the date's all hosed I'm rebooting into debain on the glomation`
