`00:01.37`	`[g2-lap]`	`lennert ping`
`00:01.54`	`lennert`	`pong`
`00:02.00`	`[g2-lap]`	`I'm back`
`00:02.10`	`[g2-lap]`	`out with the kids a little`
`00:02.10`	`lennert`	`good`
`00:02.13`	`lennert`	`nice`
`00:02.18`	`lennert`	`i was watching a political debate`
`00:02.23`	`lennert`	`the first i've seen in 6 years`
`00:02.24`	`lennert`	`anyway`
`00:02.26`	`[g2-lap]`	`heh`
`00:02.31`	`lennert`	`can you try uncommenting the gpio port c stuff?`
`00:02.39`	`lennert`	`just put the a/b/d stuff between #if 0`
`00:02.44`	`lennert`	`i probably messed those up somehow`
`00:02.52`	`[g2-lap]`	`Ok`
`00:02.57`	`lennert`	`it should work then`
`00:04.52`	`[g2-lap]`	`lennert :)`
`00:04.57`	`[g2-lap]`	`<PROTECTED>`
`00:04.57`	`[g2-lap]`	`Debug: jtag.c:1043 jtag_init():`
`00:04.57`	`[g2-lap]`	`gpio_data_register = 40015008`
`00:04.57`	`[g2-lap]`	`gpio_data_direction_reg = 40015018`
`00:04.57`	`[g2-lap]`	`Debug: jtag.c:937 jtag_reset_callback():`
`00:05.00`	`[g2-lap]`	`Error: jtag.c:989 jtag_validate_chain(): Error validating JTAG scan chain, IR mismatch`
`00:05.03`	`lennert`	`that's much better`
`00:05.05`	`lennert`	`hmmm`
`00:05.09`	`lennert`	`nothing connected? :P`
`00:05.14`	`[g2-lap]`	`right`
`00:05.22`	`lennert`	`can you check if something happens on TCK?`
`00:05.33`	`lennert`	`for example.. delay one second every time TCK/TDO/TMS get changed`
`00:05.37`	`lennert`	`just put a sleep(1); in there`
`00:05.45`	`lennert`	`and check with your meter whether the pin for TCK toggles`
`00:06.06`	`[g2-lap]`	`yeah I could`
`00:06.30`	`[g2-lap]`	`I think just working out the pinouts and connecting it up to something will help`
`00:06.36`	`lennert`	`yup`
`00:06.39`	`lennert`	`make sure the levels match`
`00:06.49`	`[g2-lap]`	`I want to check the levels too before hooking it up to a board`
`00:06.51`	`lennert`	`or put some converter in between`
`00:06.51`	`lennert`	`yeah`
`00:07.02`	`[g2-lap]`	`I've got plenty of boards`
`00:07.16`	`lennert`	`you do :P`
`00:07.20`	`[g2-lap]`	`I think there are 4 gounds on the bottom of that connector`
`00:07.35`	`[g2-lap]`	`that connector being the keyboard connectors`
`00:07.46`	`[g2-lap]`	`so I think we can have a reasonable ground connection`
`00:08.47`	`[g2-lap]`	`I think I could just pull the init code out and drive the IOs directly`
`00:08.55`	`[g2-lap]`	`in a little program`
`00:08.59`	`lennert`	`sure`
`00:09.33`	`[g2-lap]`	`it kinda amazing this was just an idea about 48 hours ago if that`
`00:09.49`	`[g2-lap]`	`at least to me anyway`
`00:09.57`	`lennert`	`well, yeah`
`00:10.02`	`lennert`	`you prodded me to check the gpio speed`
`00:10.08`	`lennert`	`i checked and remarked we could do jtag with that`
`00:10.19`	`[g2-lap]`	`step by step..`
`00:10.23`	`[g2-lap]`	`inch by inch`
`00:10.31`	`[g2-lap]`	`boom there you are :)`
`00:10.32`	`lennert`	`ferrari by ferrari`
`00:10.51`	`[g2-lap]`	`speed-o-light by speed-o-light :)`
`00:19.07`	`[g2-lap]`	`Ok I'm I've got pins 1 3 5 7 9 11 hooked up on the header`
`00:19.16`	`[g2-lap]`	`s/I'm//`
`00:38.05`	`[g2-lap]`	`lennert I'm getting some values`
`00:38.10`	`[g2-lap]`	`they are 3.3v`
`00:44.40`	`[g2-lap]`	`lennert I'm driving TCLK`

`00:47.08`	`[g2-lap]`	`I guess there is :)`
`00:57.08`	`[g2-lap]`	`vmaster around ?`
`01:21.41`	`[g2-lap]`	`I wanted to ask what would happen if I was hooked up to a wrong device`
`01:22.00`	`[g2-lap]`	`if it'd just scan the device and report back`
`01:22.27`	`[g2-lap]`	`dwery I think openOCD is running on my glomation board`
`01:22.43`	`dwery`	`openOCD is a jtag tool, right?`
`01:22.48`	`[g2-lap]`	`dunno if you followed the measurements lennert made yesterday`
`01:22.54`	`[g2-lap]`	`yup vmaster's`
`01:22.58`	`dwery`	`I gave a quick look`
`01:23.11`	`dwery`	`and you are using gpio to do it, right?`
`01:23.13`	`[g2-lap]`	`we should be able to drive near 8Mhz`
`01:23.20`	`[g2-lap]`	`yeah`
`01:23.26`	`[g2-lap]`	`bit bang'n`
`01:23.37`	`dwery`	`so this is considerably faster than the method that were available as of today?`
`01:23.55`	`[g2-lap]`	`vmaster was saying the parallel today is about 350K`
`01:24.19`	`[g2-lap]`	`so if we go to 4M it'll be 10x+ faster`
`01:24.33`	`dwery`	`ok.. what are openOCD capabilities in terms of flash/cpld programming?`
`01:25.06`	`[g2-lap]`	`I think there's some flashing, but more important there's some debug capability`
`01:25.13`	`dwery`	`great!`
`01:25.17`	`[g2-lap]`	`we'll be able to debug boot code etc...`
`01:25.25`	`[g2-lap]`	`or kernel stuff`
`01:25.33`	`dwery`	`and congrats`
`01:26.09`	`[g2-lap]`	`well it's not all done yet but we've made great progress`
`01:26.23`	`[g2-lap]`	`thx from the team :)`
`01:26.43`	`[g2-lap]`	`beewoolie's stuff it built too`
`01:27.00`	`[g2-lap]`	`but there's no gpio driver yet`
`01:27.26`	`[g2-lap]`	`vmaster has a telenet and gdb backend/front-end`
`01:27.35`	`[g2-lap]`	`which ever end you think of it aas`
`01:27.37`	`[g2-lap]`	`as`
`03:03.43`	`*** join/#openjtag dwery (n=dwery@nslu2-linux/dwery)`
`03:25.01`	`*** join/#openjtag ByronT_ (n=byron-po@nslu2-linux/ByronT)`
`08:31.42`	`koen`	`good morning all`
`08:32.18`	`lennert`	`morning`
`08:32.52`	`ka6sox`	`mawnin`
`08:33.00`	`lennert`	`good yawnin'`
`08:33.05`	`lennert`	`[g2-lap]: sorry, i fell asleep`
`09:49.34`	`[g2]`	`lennert great! sleep is a good thing :)`
`09:53.27`	`[g2]`	`vmaster up yet ?`
`09:55.48`	`vmaster`	`[g2]: yeah`
`09:56.18`	`[g2]`	`vmaster the port C stuff was toggling the GPIO lines last night`
`09:56.26`	`vmaster`	`oh, nice`
`09:56.31`	`[g2]`	`I had an LED on a 1 second`
`09:56.54`	`[g2]`	`Light Dark Light Dark ....`
`09:57.18`	`vmaster`	`the openocd verifies that the specified jtag chain is correct, by doing an instruction register scan`
`09:57.24`	`[g2]`	`So my question for you was about OCD`
`09:57.41`	`[g2]`	`does it print out the result ?`
`09:57.56`	`vmaster`	`it quits if the check failed`
`09:58.06`	`vmaster`	`but you can enable extensive debug logging`
`09:58.07`	`[g2]`	`sure (as it should)`
`09:58.08`	`vmaster`	`in jtag.h`
`09:58.35`	`vmaster`	`there's a #define _DEBUG_JTAG_IO_`
`09:58.37`	`[g2]`	`I meant it should fail that's a good sanity check`
`09:58.49`	`[g2]`	`I saw that the other ay`
`09:58.53`	`[g2]`	`s/ay/day/`
`09:59.44`	`[g2]`	`and right now there's arm7 and arm9 but now Xscale support right ?`
`09:59.51`	`vmaster`	`yeah`
`10:00.05`	`vmaster`	`i've started looking into xscale, but this is going to take some time`
`10:00.48`	`[g2]`	`sure`
`10:01.08`	`[g2]`	`I'm not too worried about that`
`10:01.58`	`[g2]`	`you currently have some gdb support for arm7 and arm9 right ?`
`10:02.06`	`vmaster`	`yeah`
`10:02.35`	`vmaster`	`well, generic gdb support, as long as the target specific code implements the interface defined in target.h`
`10:02.37`	`[g2]`	`so if we wanted to use openOCD do debug say a bootloader on the ARM9 we could`
`10:02.42`	`vmaster`	`yes`
`10:02.55`	`[g2]`	`that's _just_ _cool_`
`10:05.02`	`[g2]`	`Ok I'll see if I can dig up a arm9 target that's got JTAG brought ut`
`10:05.08`	`[g2]`	`s/ut/out/`
`10:06.07`	`vmaster`	`you can test the jtag functionality with anything that's got a jtag connector`
`10:06.38`	`vmaster`	`the telnet interface offers low-level jtag commands, like ir-scans, dr-scans, runtest, etc.`
`10:07.15`	`[g2]`	`Ok`
`10:07.35`	`[g2]`	`so I don't need to enable the low-level stuff`
`10:08.13`	`vmaster`	`the low level commands are always there`
`10:08.25`	`vmaster`	`the target commands are only there when a valid "target ..." configuration line was found`
`10:09.53`	`[g2]`	`vmaster around for 5 minutes ?`
`10:10.13`	`vmaster`	`for several hours, i guess`
`10:11.25`	`[g2-lap]`	`I'm like 6 pins being hooked up to a CPLD`
`10:11.44`	`[g2-lap]`	`then we can run the telnet and and do some JTAG scans`
`10:12.05`	`vmaster`	`yeah`
`10:12.21`	`vmaster`	`if it's a coolrunner you could even program it`
`10:12.51`	`[g2-lap]`	`XC9572`
`10:13.01`	`vmaster`	`well, could work, too, but not tested yet`
`10:13.07`	`vmaster`	`mhh, maybe not`
`10:13.20`	`vmaster`	`but at least you can scan the idcode`
`10:13.48`	`[g2-lap]`	`that's all we really need`
`10:13.59`	`[g2-lap]`	`then POC is done`
`10:14.09`	`[g2-lap]`	`that uses all the lines right ?`
`10:14.24`	`vmaster`	`tdi, tms, tck and tdo would be enough`
`10:14.30`	`vmaster`	`trst makes things easier`
`10:14.44`	`vmaster`	`srst is only required to do target resets (and mandatory for xscale)`
`10:15.09`	`[g2-lap]`	`ok 4 of the lines which is plenty`
`10:15.18`	`[g2-lap]`	`plenty for POC`
`10:26.15`	`vmaster`	`that's the jtag_device line you should use for a xc9500:`
`10:26.16`	`vmaster`	`jtag_device 8 0x01 0x03 0xfe`
`10:26.45`	`vmaster`	`8 bit IR register, captures 0x1 during Capture-IR, first 2 bits should be checked, idcode instruction is 0xfe`
`10:33.45`	`[g2-lap]`	`vmaster OK I'm ready to go`
`10:34.13`	`[g2-lap]`	`do I pass a config if I'm just gonna telnet in ?`
`10:34.20`	`vmaster`	`yeah`
`10:34.25`	`vmaster`	`hold on`

`10:38.43`	`[g2-lap]`	`sure`
`10:39.10`	`[g2-lap]`	`BTW thx for taking the time for all the hand-holding with me !`
`10:39.33`	`vmaster`	`heh, thx for porting the openocd to your platform`
`10:42.27`	`[g2-lap]`	`my pleasure :)`

`10:45.55`	`vmaster`	`it reads back all 1s`
`10:46.10`	`vmaster`	`so either the output or the input didn't work :)`
`10:46.49`	`[g2-lap]`	`vmaster I've got a 4 led segment I can drive`
`10:47.06`	`[g2-lap]`	`we can check the 3 output pins`
`10:47.14`	`[g2-lap]`	`then check the 1 input`
`10:49.54`	`vmaster`	`ok, tck and tdi should start at 0, tms should start at 1`
`10:50.13`	`vmaster`	`then tck should toggle 7 times`
`10:52.13`	`lennert`	`wow, lots of discussion`
`10:53.41`	`lennert`	`i _think_ i did the reset values correctly`
`11:09.07`	`[g2-lap]`	`Ok a little desk clean up`
`11:09.39`	`[g2-lap]`	`I'm hooked up with a 4 LEDs to TDO, TDI, TCLK and TMS`
`11:09.50`	`lennert`	`(i hope you have series resistors :)`
`11:10.15`	`lennert`	`TDO is an input as far as the ep93xx is concerned, so it will not drive that pin`
`11:10.26`	`lennert`	`but TDI/TCK/TMS/TRST/SRST should 'work'`
`11:19.03`	`[g2-lap]`	`Ok I'm driving the LEDs`
`11:19.21`	`[g2-lap]`	`I'll need to separate out a BIT at a time`
`11:20.29`	`[g2-lap]`	`actually I think we are pretty OK`
`11:22.19`	`[g2-lap]`	`the real question is what is VCC for the XC95`
`11:23.37`	`vmaster`	`there are three variants of the xc95`
`11:25.21`	`vmaster`	`plain xc9500 is 5v, xc9500xl is 3.3v and xc9500xv is 2.5v`
`11:30.59`	`[g2-lap]`	`great`
`11:31.04`	`[g2-lap]`	`we've got an XL :)`
`11:31.40`	`lennert`	`[g2-lap]: we might still want to use some kind of interface logic to allow it to use multiple different voltages`
`11:32.10`	`[g2-lap]`	`lennert absolutely`
`11:32.22`	`[g2-lap]`	`but that's a VL thingy`
`11:32.30`	`lennert`	`VL ?`
`11:32.33`	`lennert`	`Very much Later? :)`
`11:32.42`	`[g2-lap]`	`voltage level :)`
`11:33.13`	`[g2-lap]`	`well kill that dragon when we handle the high-speed rates`
`11:33.20`	`lennert`	`ok`
`11:33.25`	`[g2-lap]`	`lennert vmaster I think I know what the issue is`
`11:34.05`	`[g2-lap]`	`TDI is with respect to the DUT (device under test) right ?`
`11:34.28`	`lennert`	`TDI is an output to the ep93xx`
`11:34.32`	`lennert`	`TDO is an input to the ep93xx`
`11:34.45`	`[g2-lap]`	`right that's what I said`
`11:34.51`	`lennert`	`right`
`11:35.10`	`[g2-lap]`	`TDO looks stuck high`
`11:35.20`	`[g2-lap]`	`I'll have to verify my LED thingy`
`11:35.39`	`[g2-lap]`	`but TDI TMS and TCK all blink right`
`11:35.45`	`lennert`	`well`
`11:35.51`	`lennert`	`the ep93xx doesn't drive the TDO pin`
`11:35.54`	`vmaster`	`TDO only operates during Shift-IR/DR`
`11:36.04`	`vmaster`	`other than that it should be HighZ`
`11:36.16`	`[g2-lap]`	`pulled high ?`
`11:36.33`	`vmaster`	`i've seen all kinds of pull up/down on the jtag lines`
`11:36.39`	`vmaster`	`pulling high is recommended`
`11:36.44`	`lennert`	`[g2-lap]: try shorting the TDO pin to Vcc/GND with a 1kohm resistor and check whether the ep93xx can read the right values`
`11:37.09`	`lennert`	`[g2-lap]: if not, there's either someone pulling/pushing it already or you don't have the right pin`
`11:37.18`	`AchiestDragon`	`4k7`
`11:39.53`	`[g2-lap]`	`maybe it defaults high on my little LED gizmo`
`11:40.12`	`[g2-lap]`	`the other option is we are driving the JTAG too fast :)`
`11:40.44`	`AchiestDragon`	`the leds can affect it depeding how your driving them`
`11:41.07`	`[g2-lap]`	`AchiestDragon these are mutally exclusive tests`
`11:41.23`	`[g2-lap]`	`the LED gizmo is plugged in or the JTAG device`
`11:41.26`	`vmaster`	`[g2-lap]: yeah, that could be a problem`
`11:41.29`	`[g2-lap]`	`not both at the same time`
`11:41.31`	`vmaster`	`driving to fast`
`11:41.53`	`[g2-lap]`	`we are probably driving TCLK pretty fast`
`11:42.17`	`AchiestDragon`	`if using a transistor buffer to drive the leds you should be able to use them both at the same time`
`11:44.40`	`[g2-lap]`	`AchiestDragon at slow rates :)`
`11:44.54`	`[g2-lap]`	`at 15Mcycles per second I need help :)`
`11:45.08`	`[g2-lap]`	`electronic eyes`
`11:45.54`	`AchiestDragon`	`not shure on the ep93xx but on the pic micros you can read and write to the port faster than the port will respond , so the signal may not be raiseing to a full logic 1 state before dropping back to a 0`
`11:45.56`	`lennert`	`or you just slow it down by a factor of 15 million :-)`
`11:46.17`	`lennert`	`AchiestDragon: that could be happening on the ep93xx as well`
`11:46.30`	`lennert`	`AchiestDragon: drive strength is kind of limited`
`11:46.43`	`AchiestDragon`	`you need a scope on the output see if the waveform looks ok`
`11:48.36`	`AchiestDragon`	`my scope died of old age last year not replaced it yet`

`11:53.30`	`[g2-lap]`	`dwery thx, but do you have a scope ?`
`11:53.51`	`dwery`	`a small one`
`11:53.57`	`dwery`	`how many MHz do you need?`
`11:54.14`	`lennert`	`the signal is 20 MHz max`
`11:54.30`	`[g2-lap]`	`and how many channels ?`
`11:54.43`	`lennert`	`just to look at the waveform, you need only 1?`
`11:55.23`	`[g2-lap]`	`actually well want to see the relationship between the signals`
`11:55.35`	`[g2-lap]`	`but 2 channels would be enough`
`11:55.49`	`[g2-lap]`	`through the transitive property`
`11:56.13`	`[g2-lap]`	`it's all slaved to TCLK anyway right ?`
`11:56.20`	`vmaster`	`yeah`
`11:56.33`	`vmaster`	`signals should change on the falling edge of tck`
`11:57.08`	`[g2-lap]`	`I'm guessing we are just plain driving the signals too fast`
`11:57.18`	`lennert`	`[g2-lap]: then put a delay in there :-)`
`11:57.37`	`[g2-lap]`	`lennert I was looking for that but I think it's been removed :)`
`11:57.54`	`lennert`	`struct timespec zzzz;`
`11:57.57`	`lennert`	`zzzz.tv_sec = 0;`
`11:58.06`	`lennert`	`zzzz.tv_nsec = 10000000;`
`11:58.12`	`lennert`	`nanosleep(&zzzz, NULL);`
`11:58.24`	`lennert`	`after every write to the data register`
`11:58.27`	`lennert`	`just to see if it works`
`11:58.46`	`[g2-lap]`	`that'll work`
`11:58.56`	`[g2-lap]`	`vmaster had a delay counter`
`11:59.34`	`vmaster`	`but that delay was only useful with x86`
`11:59.49`	`vmaster`	`i've simply repeated the outb calls`
`12:00.07`	`lennert`	`you can do that on ep93xx as well`
`12:00.11`	`lennert`	`each write is 20-ish cycles`
`12:00.43`	`vmaster`	`ah, yeah, sure`
`12:01.02`	`lennert`	`we can also just make a kernel driver and watch it sloooooooooooooow down :)`
`12:01.14`	`vmaster`	`hehehe`
`12:06.47`	`dwery`	`mm.. my scope might not be fast enough`
`12:11.24`	`[g2-lap]`	`dyoung-away up ?`
`12:11.51`	`dyoung-away`	`for you yes`
`12:12.29`	`dwer-away`	`bbl`
`12:22.08`	`[g2-lap]`	`dyoung-away hey ;)`
`12:23.14`	`[g2-lap]`	`dyoung-away sometime I'm wondering if you could put a scope on glomation`
`12:23.21`	`dyoung-away`	`Sure`
`12:23.29`	`dyoung-away`	`If you can help me bring it up`
`12:23.30`	`lennert`	`dyoung-away: does your serial work yet?`
`12:23.33`	`lennert`	`right :)`
`12:23.42`	`dyoung-away`	`The serial is fighting me`
`12:23.52`	`[g2-lap]`	`serail on the glomation ?`
`12:23.53`	`dyoung-away`	`I have redboot prompt.`
`12:23.56`	`dyoung-away`	`yes`
`12:24.03`	`[g2-lap]`	`that's all you need and ethernet :)`
`12:24.03`	`lennert`	`oh`
`12:24.05`	`dyoung-away`	`but then I dont get anyn kernel messages`
`12:24.09`	`lennert`	`hmmm`
`12:24.13`	`lennert`	`are you running derevo14?`
`12:24.24`	`lennert`	`what load address are you using?`
`12:24.29`	`dyoung-away`	`then after some amount of time, I get "Press enter for console"`
`12:24.36`	`dyoung-away`	`This is totally factory.`
`12:24.40`	`[g2-lap]`	`sure`
`12:24.40`	`lennert`	`well, that's expected, no?`
`12:24.45`	`[g2-lap]`	`yeah :)`
`12:24.46`	`lennert`	`the stock kernel doesn't output log messages`
`12:24.51`	`dyoung-away`	`Oh`
`12:24.56`	`lennert`	`they turned that off for some reason`
`12:25.03`	`dyoung-away`	`so when I press enter for console.... ?`
`12:25.08`	`lennert`	`you get busybox`
`12:25.12`	`lennert`	`?`
`12:25.21`	`dyoung-away`	`No, I get nothing`
`12:25.29`	`lennert`	`hmm`
`12:25.30`	`dyoung-away`	`okay so it probably DOES work then`
`12:25.33`	`[g2-lap]`	`did lennert actually power on his ep9312 ?`
`12:25.38`	`lennert`	`[g2-lap]: no... :-/`
`12:25.46`	`lennert`	`[g2-lap]: i'm slack :-\|`
`12:25.54`	`dyoung-away`	`[g2-lap]: I've been slacking on the glomation`

`12:26.08`	`[g2-lap]`	`dyoung-away np`
`12:26.12`	`dyoung-away`	`but I really want to play with the thing`
`12:26.17`	`[g2-lap]`	`we've been having fun`
`12:26.46`	`dyoung-away`	`If you can outline for me what you want me to hit with a scope; I can do`
`12:26.52`	`[g2-lap]`	`dyoung-away I've got a kernel (jffs2 partition) and an OCDprogram`
`12:27.05`	`lennert`	`dyoung-away: toggle a gpio and see what the waveform looks like`
`12:27.06`	`dyoung-away`	`nothing fast though, I only have 100Mhz of scope`
`12:27.21`	`lennert`	`we can only toggle at 15 MHz or so :)`
`12:27.47`	`dyoung-away`	`[g2-lap]: I dontsuppose I could interest you in send me your image? :-)`
`12:28.33`	`[g2-lap]`	`that's exactly what I'm thinking`
`12:28.51`	`dyoung-away`	`I can do it i around 8hrs or so`
`12:29.01`	`dyoung-away`	`I'm getting a bit sleepy....`
`12:29.01`	`[g2-lap]`	`I'm wondering which libraries the openocd stuff uses`
`12:29.14`	`dyoung-away`	`but I have the scope out; its ready for action`
`12:29.14`	`[g2-lap]`	`dyoung-away Ok that'll be great`
`12:29.27`	`[g2-lap]`	`by then you should have a kernel and jffs2 partition`
`12:29.31`	`dyoung-away`	`I also have the GEBC9312 out`
`12:30.28`	`[g2-lap]`	`you can just load and flash the jffs2 then load the kernel and boot to the rootfs on flash`
`12:30.28`	`vmaster`	`[g2-lap]: libc`
`12:30.41`	`vmaster`	`no other dependencies`
`12:31.03`	`[g2-lap]`	`vmaster lennert I put the nanosleep in and get the same results`
`12:31.07`	`dyoung-away`	`how much detail do you want on this waveform?`
`12:31.09`	`[g2-lap]`	`I didn't delay the read`
`12:31.37`	`dyoung-away`	`if you need detail, I can take it to the office and slap a good scope on it.`
`12:32.42`	`dyoung-away`	`no promises on that though, because the boss said something about taking the scope to Britanny.`
`12:33.05`	`dyoung-away`	`what am I scoping?`
`12:33.13`	`lennert`	`one of the GPIO lines`
`12:33.15`	`[g2-lap]`	`I don't think we'll need a lot of detail`
`12:33.29`	`dyoung-away`	`is there a redboot command I can use?`
`12:33.38`	`dyoung-away`	`or do I really need [g2] image?`
`12:33.56`	`[g2-lap]`	`dyoung-away you'll want the image`
`12:34.49`	`[g2-lap]`	`dyoung-away I think we are a little timing issue away from doing JTAG debugging on ARM7/9 with the glomation`
`12:34.49`	`dyoung-away`	`ok I do tommrow then. :-)`
`12:35.06`	`[g2-lap]`	`dyoung-away you know where the wiki is ?`

`12:36.19`	`dyoung-away`	`Yes`
`12:36.28`	`dyoung-away`	`so I want to hit J30 ?`
`12:36.44`	`[g2-lap]`	`Ok I'll add a page for the OCD stuff`
`12:37.08`	`[g2-lap]`	`J8`
`12:38.25`	`dyoung-away`	`ok thats pretty easy access`
`12:44.31`	`[g2-lap]`	`dyoung-away vmaster lennert on the Xilinx DLC5 cable VCC is an output from the device right :?`
`12:45.03`	`[g2-lap]`	`or is it an input to the device ?`
`12:45.06`	`lennert`	`not sure, vmaster probably knows`
`12:45.06`	`dyoung-away`	`the vcc pin provides the power to the DLC5`
`12:45.49`	`[g2-lap]`	`Ok then I think that's my problem`
`12:46.23`	`[g2-lap]`	`I had an unpowered device connected on the cable`
`12:46.36`	`[g2-lap]`	`and I'm driving VCC from the EP9312`
`12:47.10`	`[g2-lap]`	`what I should be doing is powering this device and have VCC not connected`
`12:47.35`	`[g2-lap]`	`just GND, TCLK, TMS, TDI and TDO`
`12:47.55`	`[g2-lap]`	`correct ?`
`12:53.49`	`dyoung-away`	`so I'm scannin g the documentation. Do you really need a Null Modem ?`
`12:56.20`	`[g2-lap]`	`dyoung-away not if you switch pins 2 and 3`
`12:56.40`	`[g2-lap]`	`I connect straight through but I've swapped 2 and 3`
`12:56.58`	`dyoung-away`	`I connect straight through, and I'm using all straight cables, so....`
`12:57.05`	`[g2-lap]`	`I think I've got pin 3 on the glomation connected to DB-9 pin 2`
`12:57.43`	`[g2-lap]`	`dyoung-away we may not need the scope btw :)`
`12:58.15`	`lennert`	`[g2-lap]: it's working?`
`12:58.30`	`[g2-lap]`	`lennert no :( but I've got an idea :)`

`15:30.45`	`lennert`	`SERDES`
`15:30.58`	`lennert`	`if you want GMII you need an additional ixf1104 or pmc/sierra 3386 or something`
`15:31.05`	`lennert`	`this is for gigabit, right?`
`15:31.17`	`[g2-lap]`	`no, but gigabit would work`

`15:32.43`	`[g2-lap]`	`hey I'm all for getting stuff manufactured`
`15:33.12`	`lennert`	`go with the intel ixf1104 then, it's a load cheaper than the pmc/sierra`
`15:33.33`	`[g2-lap]`	`I don't need GMII`
`15:33.41`	`[g2-lap]`	`and I don't need SERDES`
`15:34.35`	`[g2-lap]`	`gigE would work fine`
`15:35.01`	`[g2-lap]`	`it'll send nearly 120MB over the link point to point`
`15:35.19`	`[g2-lap]`	`per second :)`
`15:35.28`	`lennert`	`well, most GigE transceivers use either SERDES, GMII, or SPI3`
`15:35.42`	`lennert`	`SPI3 is one of the easier protocols to speak`

`15:36.10`	`lennert`	`32 bit data path running at 50 MHz or so should be enough for a single gigabit pipe`
`15:36.17`	`lennert`	`i think you can make the S3 speak SPI3`
`15:36.33`	`lennert`	`the S3 certainly won't speak SERDES, as SERDES is 1.25 giga-baud`
`15:36.41`	`lennert`	`basically, SERDES is what goes into the laser`
`15:36.57`	`[g2-lap]`	`or a backplane :)`
`15:37.05`	`lennert`	`or a backplane :)`
`15:37.26`	`lennert`	`spi3 is probably easiest`
`15:37.42`	`lennert`	`the ixf1104 is a quad gige phy`

`15:38.09`	`[g2-lap]`	`is there an ixf1101 ?`
`15:38.19`	`lennert`	`but you can always run it at a lower rate (or a decrease in available bandwidth)`
