| 12:27.02 | hamishm | hi |
| 12:27.23 | hamishm | i'm wondering what the state of openjtag is and whether the Gateworks GW16012 dongle is supported.. |
| 12:27.33 | hamishm | can't seem to access the openjtag.net site right now |
| 12:29.44 | hamishm | anyone able to help? |
| 12:31.17 | vmaster | there's no software from openjtag afaik |
| 12:31.25 | hamishm | ah |
| 12:31.27 | vmaster | but the GW16012 is supported by the OpenOCD |
| 12:31.43 | vmaster | what do you want to use it for? |
| 12:31.59 | hamishm | I want to be able to program flash primarily |
| 12:32.15 | hamishm | Tried openwince-jtag but it doesn't support the GW16012 |
| 12:32.29 | vmaster | what flash connected to which target? |
| 12:32.42 | hamishm | IXP425 |
| 12:34.01 | vmaster | [g2] tried the OpenOCD with a GW16012 and a IXP42x but it wasn't really successfull - the GW16012 operates close to the IXP's JTAG frequency limit, and my guess was that small problems with the cable and board layout could corrupt the communication |
| 12:34.23 | hamishm | mostly I am looking for a solution for programming flash via the IXP425 under linux.. |
| 12:34.51 | hamishm | OCD could be useful at a later date.. |
| 12:35.06 | vmaster | OpenOCD supports flash programming, too |
| 12:35.16 | hamishm | as we are expecting new boards soon and might have issues commissioning those |
| 12:36.09 | hamishm | I'm looking at the Yagarto site now.. is OpenOCD Windows-only? |
| 12:36.32 | vmaster | no, I developed it on Linux, the Windows port was added later |
| 12:37.45 | vmaster | the code is in SVN: https://developer.berlios.de/svn/?group_id=4148 |
| 12:38.09 | vmaster | you'll need branches/xscale as I haven't merged XScale support yet |
| 12:38.11 | hamishm | ok just found that. is there a release or should I just go with an svn co? |
| 12:38.16 | hamishm | ok that answers that |
| 12:40.39 | hamishm | Right now I'm using a board from Gateworks as well so I expect it'll work with their JTAG programmer |
| 12:40.54 | vmaster | after checkout, run ./boostrap, then ./configure --enable-gw16012 |
| 12:41.56 | vmaster | you can find a .cfg file at http://mmd.ath.cx/openocd/ixp42x_gw.cfg |
| 12:42.28 | vmaster | try running the OpenOCD (from ./src/) with "./openocd -f ixp42x_gw.cfg -d" |
| 12:42.54 | vmaster | it's implemented as a daemon, so if it returns to the command prompt something didn't work as expected |
| 12:44.03 | vmaster | soemone reported successful use with a IXP42x, so basically it should work with the GW, but I can't test as the only XScale board I have has a 250kHz low-pass filter on the TCK line - wonder what that engineer had in mind... |
| 12:44.27 | hamishm | eek that's rather strange |
| 12:44.50 | hamishm | I've got a GW2348 board which I want to test on for now.. custom boards coming soon |
| 12:45.31 | vmaster | okay, i'll be off for the next 2 hours or so, so good louck, and feel free to ask later today if you run into problems |
| 12:45.32 | hamishm | is there an alternative to direct i/o access (which requires root) eg /dev/parport0? |
| 12:45.37 | vmaster | ah, yeah |
| 12:45.51 | hamishm | my board is at work so I can't test it right now anyway, but I've got it compiled up for the morning |
| 12:45.55 | vmaster | --enable-parport_ppdev |
| 12:46.00 | hamishm | thanks for your help |
| 12:46.27 | vmaster | yeah, it's in the code, so ppdev should work |
| 12:46.46 | vmaster | ok, bye |
| 12:46.57 | hamishm | thanks |

| 23:26.54 | hamishm | having trouble getting OpenOCD going with IXP425 |
| 23:50.28 | hamishm | vmaster: ping |
| 23:59.38 | hamishm | i get the following pretty much instantly, regardless of eg the reset delay settings |
