| 10:50.51 | NAiL | hi there :) |
| 10:51.01 | ka6sox | got insomnia tonight |
| 10:51.10 | ka6sox | almost 4am here and I'm still up. |
| 10:52.42 | rwhitby | hey ka6sox |
| 10:52.52 | rwhitby | ka6sox: are you involved in OpenOCD? |
| 10:53.28 | ka6sox | rwhitby, nope |
| 10:53.54 | ka6sox | that would be vmaster_ |
| 10:54.06 | rwhitby | Looks like a cool project. I might be using it for work (we need to hook up Eclipse to a DSP core). |
| 10:54.20 | *** join/#openjtag p2-mate (n=p2@cable-87-244-185-244.upc.chello.be) |
| 10:54.28 | ka6sox | fun |
| 10:54.34 | ka6sox | vmaster is your guy. |
| 10:54.51 | rwhitby | Is vmaster_ a regular here? |
| 10:54.59 | ka6sox | I think that [g2] also has played with it. |
| 10:55.12 | ka6sox | ya...vmaster is here pretty regularly...he's in .de |
| 10:55.46 | rwhitby | I sent amontec an email seeing if they wanted to donate some hardware ... |
| 10:55.53 | rwhitby | www.amontec.com |
| 10:55.59 | ka6sox | good plan. |
| 11:19.16 | vmaster_ | hey |
| 11:19.29 | ka6sox | morning vmaster. |
| 11:19.36 | rwhitby | hey vmaster |
| 11:19.41 | vmaster | morning ka6sox, hey rwhitby |
| 11:19.53 | rwhitby | I hear you're the OpenOCD expert around these parts ... |
| 11:20.11 | rwhitby | Are you on the development team of it? |
| 11:20.22 | vmaster | guess i am the development team ;) |
| 11:20.47 | vmaster | a few contributions from others, mostly bug fixes, and support for flash chips i don't own |
| 11:20.53 | rwhitby | ah, you're Dominic? |
| 11:20.58 | vmaster | yeah |
| 11:21.04 | rwhitby | Pleased to meet you. |
| 11:21.24 | rwhitby | I was just reading through your code, seeing how difficult it would be to add support for some Freescale processors ... |
| 11:22.16 | vmaster | that really depends on the debug hardware used by freescale |
| 11:22.26 | vmaster | arm7/9 and xscale for example is almost completely different |
| 11:22.35 | vmaster | only the jtag stuff and architecture is the same |
| 11:22.42 | vmaster | armv4/5t |
| 11:22.58 | vmaster | oh yeah, and the gdb stuff |
| 11:25.16 | rwhitby | My company (www.astc-design.com) is looking to connect Eclipse to some Freescale chips, and OpenOCD looks (on the face of it) to be a good platform for that sort of work ... |
| 11:25.33 | vmaster | is there public documentation available on these chips? |
| 11:25.50 | rwhitby | Good question. |
| 11:26.52 | rwhitby | I know they give out Debug Access information to companies like Green Hills Software, etc. |
| 11:27.01 | rwhitby | Not sure whether it's under NDA or not. |
| 11:27.27 | rwhitby | The chip data books should have debug access chapters in them ... |
| 11:31.06 | ka6sox | boo hisss...green hills....they are here in town. |
| 11:39.52 | rwhitby | vmaster: here's an offer from the nslu2-linux project - we'll buy you a slug if you want to get OpenOCD to work with the NSLU2. |
| 11:41.51 | rwhitby | vmaster: the Freescale chips we're looking at have the "EOnCE" (Enhanced On-Chip Emulation) block for debug access through jtag, and it's documented in the chip user manual. |
| 11:42.01 | rwhitby | (e.g. for the 56800E DSP core) |
| 11:45.37 | vmaster | heh, that would be really cool |
| 11:46.08 | vmaster | i'm having exams once again the next two weeks, so i wont work on the xscale stuff for some time, but after that I'd be glad to t |
| 11:46.13 | vmaster | talk to you about your offer |
| 11:46.36 | vmaster | i'll have a look at the freescale EOnCE |
| 11:46.42 | rwhitby | Do you have a way to buy an NSLU2 locally? Or would you require one to be shipped from the US? |
| 11:47.11 | rwhitby | (If you can get one locally, we can just PayPal you the cost) |
| 11:47.21 | vmaster | i can get one locally |
| 11:47.36 | rwhitby | what's the cost (in USD$)? |
| 11:47.59 | wookey | has dave bisset turned up on this channel to talk to anyone yet? |
| 11:48.06 | wookey | he's the balloon 3 JTAG guy |
| 11:48.17 | wookey | I suspect not so I'll kick him again |
| 11:48.20 | vmaster | i don't think so |
| 11:48.33 | rwhitby | vmaster: is this the main place on IRC where you discuss OpenOCD? |
| 11:48.47 | wookey | (hi rwhitby) |
| 11:49.00 | vmaster | if ever, than in #openjtag, i guess |
| 11:49.15 | vmaster | i'll grab something for lunch, bbiab |
| 11:49.30 | rwhitby | I'll be gone to bed by then. |
| 11:49.38 | rwhitby | Catch you another day. Good luck with the exams. |
| 11:51.26 | wookey | vmaster: I see that xscale support is 'coming along nicely' on june 12th. Does that mean we can use it for uploading files already, or is more needed? |
| 11:51.39 | wookey | (we are using pxa270) |
| 11:52.31 | rwhitby | wookey: is your company considering using OpenOCD? |
| 11:52.42 | wookey | yes |
| 11:53.08 | wookey | we currently have our own jtag tools which are a re-wrtitten (and much better) multi-chain jflash |
| 11:53.11 | wookey | called bflash |
| 11:53.39 | rwhitby | wookey: From your knowledge of OpenOCD, would it be able to support multi-core debugging? |
| 11:53.44 | wookey | but we need some high-speed hardware and tools to the sort of thing XJTAG lets us do, but without everyone having to pay $18,000 |
| 11:54.06 | wookey | My knowledge is negligible, except for a talk vmaster gave at FOSDEM this year |
| 11:54.25 | rwhitby | oh, is there an online copy of that talk somewhere I can look at? |
| 11:54.41 | wookey | if openOCD and similar tools are the right sort of thing then it makes sense for us to develop that rather than NIH it |
| 11:54.52 | rwhitby | wookey: my feelings exactly |
| 11:55.12 | ka6sox | I think I saw a copy of the talk at one time.... |
| 11:55.20 | ka6sox | but I may be misteaken |
| 11:55.33 | *** join/#openjtag p2-mate (n=p2@cable-87-244-185-244.upc.chello.be) |
| 11:55.37 | wookey | it was actually about openjtag. I'm not sure if openjtag==openOCD |
| 11:55.47 | wookey | probably |
| 11:56.05 | wookey | rwhitby: fodem.org seems to be down right now |
| 11:56.06 | rwhitby | aha: http://free-electrons.com/community/videos/conferences |
| 11:56.11 | wookey | look for the embedded track |
| 11:56.13 | rwhitby | (from http://lwn.net/Articles/173968/) |
| 11:56.22 | wookey | ah yes - he videoed it all - very handy |
| 11:57.22 | ka6sox | http://openocd.berlios.de/OpenOCD_Fosdem2006_talk.odp |
| 11:58.04 | ka6sox | those are the slides |
| 11:58.43 | rwhitby | ka6sox: thx |
| 11:59.06 | ka6sox | np |
| 12:00.46 | rwhitby | also ftp://ftp.belnet.be/pub/mirror/FOSDEM/ |
| 12:04.22 | ka6sox | excellent |
| 12:04.51 | rwhitby | Now I need to find a windows ogg player so i can watch them at work :-) |
| 12:05.03 | vmaster | heh |
| 12:05.11 | vmaster | the talk is more about how openocd works, than how to use it |
| 12:05.21 | rwhitby | that's good. |
| 12:05.35 | ka6sox | in order to port it to another arch thats what is needed. |
| 12:05.39 | rwhitby | (especially for someone considering contributing to it) |
| 12:05.50 | vmaster | mhh, not sure, it's a bit arm7/9 centric |
| 12:06.13 | wookey | vmaster: what is the strongarm suport like? |
| 12:06.21 | vmaster | there is no strong |
| 12:06.23 | vmaster | arm support |
| 12:06.35 | vmaster | the slide just shows the arm cores |
| 12:07.01 | vmaster | ah, and "coming along nicely" means i got the basics working, but all the details have to be filled in |
| 12:07.28 | wookey | OK, thanx. I will try to find time to take a proper look |
| 12:07.59 | vmaster | the svn branch is horribly outdated - i'll let you know once there's something usable |
| 12:08.44 | vmaster | currently i'm trying to get the OpenOCD build a native-windows version, without too many hacks |
| 12:09.07 | rwhitby | vmaster: you don't work in the svn repo? |
| 12:09.28 | vmaster | well, yeah, but I lack the discipline |
| 12:09.53 | vmaster | sure, i could check everything in the way it is now |
| 12:10.39 | vmaster | i try to do only small, documented changes on the /trunk |
| 12:11.50 | vmaster | the xscale branch gets huge updates once i have all the bits working together |
| 12:12.29 | rwhitby | Has the underlying architecture changed? i.e. could someone use the current trunk as the basis to port to a new type of processor? |
| 12:13.14 | vmaster | some very minor changes to the JTAG support, as XScale is a bit picky on how you move through the state machine |
| 12:14.58 | vmaster | multi-core debugging should be possible, at least Laurent from Amontec reported that he used it on a board with two arm cores |
| 12:15.29 | vmaster | davidc__: was having problems though, with his IPod, but then I know nothing about how these cores are connected |
| 12:15.36 | rwhitby | heh, I was just talking to Laurent from Amontec on email tonight, asking for hardware donations to nslu2-linux ;-) |
| 12:16.09 | vmaster | Olimex is going to sell something similar |
| 12:16.21 | vmaster | you might want to ask them, too |
| 12:18.15 | ka6sox | OLIMEX==Sparkfun in US. |
| 12:18.24 | ka6sox | OLIMEX is in .bg. |
| 12:18.30 | vmaster | yeah |
| 12:18.52 | vmaster | I met Tsvetan (olimex) at the Embedded World this year in nuremberg |
| 12:19.48 | ka6sox | I love nuremberg...spend a couple of romantic nights there. |
| 12:20.18 | vmaster | yeah, the inner-city is really nice |
| 12:20.49 | rwhitby | vmaster: olimex's product is this one?: http://www.olimex.com/dev/arm-usb-ocd.html |
| 12:20.57 | vmaster | yeah |
| 12:21.22 | vmaster | it's supposed to sell for around 60$ |
| 12:21.48 | vmaster | 1/3 of the amontec device |
| 12:22.21 | ka6sox | still uses the FT2232? |
| 12:22.33 | vmaster | i think so, although i haven't seen it yet |
| 12:22.45 | vmaster | but he asked me how they should do the pin-out to have it work with OpenOCD |
| 12:23.01 | vmaster | Amontec is planning to do a cheaper version, too |
| 12:23.11 | ka6sox | k |
| 12:24.30 | wookey | does openOCD support multiple JTAG chains? |
| 12:24.51 | vmaster | mhh, not multiple chains, but multiple devices in a chain |
| 12:25.08 | wookey | I recall DB saying the reason he didn't use any of the existing projects was that none supported multiple chains |
| 12:25.23 | wookey | right - we put each of our devices on it's own port, we don't chain them |
| 12:25.40 | wookey | s/it's/its/ |
| 12:25.50 | vmaster | hmm, when do you have to operate multiple chains at the same time? |
| 12:25.58 | vmaster | ah, board testing? |
| 12:26.24 | wookey | and board programming - we nee to fill nand via CPU and FPGA on second chain |
| 12:26.42 | wookey | and yes if there is a problem we want to monitor/control both |
| 12:27.49 | wookey | separate ports is much simpler for new board bringup - easier to tell which bit is working/broken |
| 12:28.17 | ka6sox | we are doing that a lot with our boards these days. |
| 12:28.23 | wookey | does this concept break openOCD architecture badly, or could it be fitted in without too much trouble? |
| 12:29.04 | vmaster | i think that could be added quite easily |
| 12:29.18 | wookey | OK - that would make us much more enthusiastic :-) |
| 12:29.35 | wookey | I can send you some hardware to play with if it helps |
| 12:29.54 | wookey | (after the exams :-) |
| 12:30.29 | wookey | he only needs to do well enough not to get kicked out... |
| 12:30.30 | ka6sox | he'll be thinking of dancing hardware. |
| 12:31.25 | vmaster | heh, these are my last three exams ever i guess |
| 12:32.20 | rwhitby | gotta go - sick child. Catch you guys later. |
| 12:32.27 | vmaster | cya |
| 12:32.49 | ka6sox | bye for now |
| 12:33.03 | ka6sox | time for sleep at 5:30 am |
| 12:33.04 | vmaster | tonight's worldcup semi-final, so i won't be online anymore in a few hours |
| 12:33.06 | vmaster | good night |
| 12:39.26 | vmaster | wookey: regarding the multiple chains - do you think you could get your JTAG guy in here? |
| 12:40.00 | wookey | I did tell him to come here, but he's not much of an IRC person. |
| 12:40.16 | wookey | he did appear in #balloon so he has got it working... |
| 12:40.28 | wookey | I'll reprod |

| 15:49.21 | vmaster | wookey: the StrongARM doesn't have debug support at all |
| 15:49.41 | vmaster | at least not the SA1100 i have on my lart |
| 15:52.21 | p2-mate | none of the strongarms has debug support afaik |
| 15:53.04 | vmaster | yeah, i think so, but only know about the sa1100 for sure |
| 15:53.30 | p2-mate | SA1110 doesn't either :) |
| 15:56.09 | vmaster | wookey: and OpenOCD is more about debugging the code than the board - reading your mail I'm not sure if this is what you want |
| 16:55.23 | wookey | vmaster: I see - so this is about using the built-in debug functionality on the CPU, not about using JTAG for simple programming (or complicated testing) |
| 16:55.55 | wookey | As you say strongarm does not have that functionality in hardware |
| 16:56.24 | wookey | So which software does have the functionality I am looking for? |
| 16:59.46 | vmaster | well, it is about programming, too, but currently not about testing |
| 16:59.55 | vmaster | i don't think there's free software |
| 17:00.03 | vmaster | we've discussed this here before, but we weren't even sure what's necessary |
| 17:01.44 | wookey | OK, so maybe our bflash could be a start others can use? |
| 17:02.43 | wookey | are you going to answer mail to point out that I have wrong end of stick, or shall I do it? |
| 17:02.57 | wookey | I expect you are about to watch footie match :-) |
| 17:08.46 | vmaster | is your bflash available online somewhere? |
| 17:16.49 | wookey | Not yet - I am hassling dave bisset to send it to me, and it will go on balloonboard.org |
| 17:21.16 | vmaster | okay, I'll reply to your mail with what OpenOCD is, and what it's not |
| 18:02.55 | davidc__ | vmaster: I'm thinking its either that the debug macrocells in my board are nonstandard, or I've got some bad electrical noise on the signal lines, or that the thing is resetting itself in the middle of debug [I've seen some fluctuations in the power supply chunk of the board that looks dodgy] |
| 18:03.03 | davidc__ | vmaster: so don't worry about my issue too much for now ;) |
| 18:05.12 | vmaster | davidc__: i have a fix for the two-targets problem |
| 18:05.17 | vmaster | i forgot an i++ ;) |
| 18:05.34 | davidc__ | vmaster: heh, I was just gonna look at that today [ just got back from vacation] |
| 18:05.40 | davidc__ | but yeah, I'll do an svn up and grab that |
| 18:06.25 | vmaster | it's not yet in svn, as i'm fighting the mingw stuff |
| 18:07.01 | vmaster | in gdb_server, gdb_init(), add "i++;" at the end of the while loop, just before or after the target = target->next |
| 18:08.34 | davidc__ | alrighty, sounds good |
| 18:10.28 | vmaster | okay, i'm off, watching the worldcup semi-finals |
