Feb 27 11:52:26 <hamishm> hi
Feb 27 11:52:47 <hamishm> i'm wondering what the state of openjtag is and whether the Gateworks GW16012 dongle is supported..
Feb 27 11:52:57 <hamishm> can't seem to access the openjtag.net site right now
Feb 27 11:55:08 <hamishm> anyone able to help?
Feb 27 11:56:41 <vmaster> there's no software from openjtag afaik
Feb 27 11:56:49 <hamishm> ah
Feb 27 11:56:51 <vmaster> but the GW16012 is supported by the OpenOCD
Feb 27 11:57:07 <vmaster> what do you want to use it for?
Feb 27 11:57:23 <hamishm> I want to be able to program flash primarily
Feb 27 11:57:40 <hamishm> Tried openwince-jtag but it doesn't support the GW16012
Feb 27 11:57:53 <vmaster> what flash connected to which target?
Feb 27 11:58:06 <hamishm> IXP425
Feb 27 11:59:25 <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
Feb 27 11:59:47 <hamishm> mostly I am looking for a solution for programming flash via the IXP425 under linux..
Feb 27 12:00:15 <hamishm> OCD could be useful at a later date.. 
Feb 27 12:00:30 <vmaster> OpenOCD supports flash programming, too
Feb 27 12:00:40 <hamishm> as we are expecting new boards soon and might have issues commissioning those
Feb 27 12:01:33 <hamishm> I'm looking at the Yagarto site now.. is OpenOCD Windows-only?
Feb 27 12:01:56 <vmaster> no, I developed it on Linux, the Windows port was added later
Feb 27 12:03:09 <vmaster> the code is in SVN: https://developer.berlios.de/svn/?group_id=4148
Feb 27 12:03:33 <vmaster> you'll need branches/xscale as I haven't merged XScale support yet
Feb 27 12:03:35 <hamishm> ok just found that. is there a release or should I just go with an svn co?
Feb 27 12:03:40 <hamishm> ok that answers that
Feb 27 12:06:02 <hamishm> Right now I'm using a board from Gateworks as well so I expect it'll work with their JTAG programmer
Feb 27 12:06:18 <vmaster> after checkout, run ./boostrap, then ./configure --enable-gw16012
Feb 27 12:07:24 <vmaster> you can find a .cfg file at http://mmd.ath.cx/openocd/ixp42x_gw.cfg
Feb 27 12:07:52 <vmaster> try running the OpenOCD (from ./src/) with "./openocd -f ixp42x_gw.cfg -d"
Feb 27 12:08:18 <vmaster> it's implemented as a daemon, so if it returns to the command prompt something didn't work as expected
Feb 27 12:09:30 <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...
Feb 27 12:09:52 <hamishm> eek that's rather strange
Feb 27 12:10:15 <hamishm> I've got a GW2348 board which I want to test on for now.. custom boards coming soon
Feb 27 12:10:55 <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
Feb 27 12:10:56 <hamishm> is there an alternative to direct i/o access (which requires root) eg /dev/parport0?
Feb 27 12:11:04 <vmaster> ah, yeah
Feb 27 12:11:15 <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
Feb 27 12:11:20 <vmaster> --enable-parport_ppdev
Feb 27 12:11:24 <hamishm> thanks for your help
Feb 27 12:11:27 * vmaster hope i enabled that for the GW dongle
Feb 27 12:11:51 <vmaster> yeah, it's in the code, so ppdev should work
Feb 27 12:12:10 <vmaster> ok, bye
Feb 27 12:12:23 <hamishm> thanks
Feb 27 22:48:59 <hamishm> vmaster: are you here? i'm back ;)
Feb 27 22:52:15 <hamishm> having trouble getting OpenOCD going with IXP425
Feb 27 23:15:49 <hamishm> vmaster: ping
Feb 27 23:24:59 <hamishm> i get the following pretty much instantly, regardless of eg the reset delay settings
Feb 27 23:25:00 <hamishm> Error:   jtag.c:1185 jtag_validate_chain(): Error validating JTAG scan chain, IR mismatch, scan returned 0x01ff
Feb 27 23:25:25 <hamishm> i'm using the ixp42x_gw.cfg
Feb 27 23:25:45 <hamishm> hardware works with the Gateworks-provided software under dosemu
Feb 28 01:44:57 <wookey_> do we have xscale support yet in openOCD?
Feb 28 01:46:41 <wookey_> ah, I see in scrollback that we do in the branch version
Feb 28 01:46:42 <wookey_> cool
Feb 28 01:47:01 <wookey_> hopefully I'll get time to try that out soon
Feb 28 01:48:17 <rwhitby> ka6sox-office: do you know if the jtag connector on the NAS100d has the reset pins required for openocd on ixp4xx?
Feb 28 02:34:34 <hamishm> I could not get OpenOCD going with IXP425 board.. error validating JTAG scan chain
Feb 28 02:44:10 <ka6sox-laptop> rwhitby, I think so.
Feb 28 02:44:13 <ka6sox-laptop> but I'll have to verify
Feb 28 02:44:23 <ka6sox-laptop> ran out of time to check today
