| 08:33.12 | jacques | is there an openocd nslu2 config file floating about? |
| 09:24.15 | jacques | the one I hacked together finds the proper JTAG device but then hangs |
| 09:24.22 | jacques | it might be a problem with reset logic |
| 09:34.01 | drath | it certainly is |
| 09:34.14 | drath | you need both reset lines, the system reset and the test reset |
| 09:34.59 | drath | and you have to be able to assert them individually, i.e. asserting sreset must NOT assert trst |
| 09:35.21 | drath | it should be possible to do this on the nslu, because someone reported it worked with a bdi2000 |
| 09:35.31 | jacques | hmm |
| 09:35.34 | drath | but i have no idea about the hardware modifications that were required |
| 09:35.45 | drath | rwhitby might know more |
| 09:36.18 | jacques | I know it works with same cable using openwince jtag tools |
| 09:36.32 | jacques | I am able to flash using that |
| 09:36.34 | drath | mhh, yeah, but the openwince jtag tools work completely different |
| 09:36.40 | jacques | oh :-\ |
| 09:36.43 | drath | they operate the ixp in boundary-scan mode |
| 09:36.50 | drath | and have no access to the chip's internals |
| 09:37.02 | jacques | yeah they are rather basic which is why I want to use openocd |
| 09:37.32 | drath | if all you want to do is flash stay with the openwince tools |
| 09:37.40 | drath | if you want to debug you'll need both reset lines |
| 09:37.57 | drath | that's a requirement of the xscale core, not the openocd |
| 09:38.10 | jacques | aha. OK good to know |
| 09:38.29 | jacques | I'll ask rwhitby about it when I see him again |
| 09:38.47 | drath | he's in this channel, too, maybe he'll read up on this |
| 09:40.05 | jacques | I am using a parallel port dlc5 if that matters |
| 09:41.18 | AchiestDragon | question ( sorry for interupting btw) but what jtag tools are avalable for doing the boundry scan testing ? and is it a sutable alternative for checking BGA devices in production other than haivng to opt to use expensive xray checking |
| 09:44.32 | drath | hmm, we had this discussion here about 1 or 2 years ago - there are tools, but they are _expensive_ |
| 09:44.59 | drath | macraigor has a little less expensive alternative to the big players |
| 09:45.09 | drath | don't remember the names of the "good" programs though |
| 09:47.04 | jacques | this might be bad: Debug: xscale.c:1550 xscale_assert_reset(): target->state: unknown |
| 09:47.19 | AchiestDragon | its for this board http://www.whipy.demon.co.uk/swarm-composite.jpg atm the companies we approched to assemble them some will do xray testing but some dont have the facilaty |
| 09:48.23 | AchiestDragon | and those that do are looking in the reagon of $2500 per board for assembly and xray test of the soldering |
