OpenOCD: JTAG communication failure, check connection, ...

Development Boards MicroMod
1

Hi all,

I have an Olimex LPC-E2214 and Olimex USB OpenOCD JTAG TINY. I installed their CD stuff with openOCD, Yagarto GCC, Eclipse and LPC-2294 examples.

I’ve seen similar postings and have tried several things they suggested, including slowing the Jtag speed, etc. Nothing seems to work. Some of the commented out stuff in the config file are the things I have tried so far.

I suspect that it could be the example code, which is really for the 2294 when the board is a 2214 with 1 MB Flash, 1 MB RAM.

I’ve also read about openOCD version issues.

As far as the jumpers on the board: the DBG_E jumper is IN, Boot 0 and Boot 1 are 11 (internal), BSL is OUT, JRST is OUT (not using RS-232).

Also, I cannot power the board from USB for some reason, even if I select the ext/usb jumper to USB. The power LED gives a quick blink then goes off. I’m powering it from an external power supply.

Sometimes the scan returned below is 0x3F, instead of 0x00.

Here’s the error messages:

Info: openocd.c:93 main(): Open On-Chip Debugger (2007-09-05 09:00 CEST)

Error: jtag.c:1253 jtag_examine_chain(): JTAG communication failure, check connection, JTAG interface, target power etc.

Hello All…

I have the same Error and i just can find the solution of my Problem. First of all i have to say that i could make debugging in the beginning. But 2 Days ago after i debugged some programm i write, i got this errors. I spent more than 2 days but i still don’t get it. I get this Errors:

$URL: http://svn.berlios.de/svnroot/repos/ope … /openocd.c $

Warning: jtag.c:1171 jtag_read_buffer(): in_handler reported a failed check

User: target.c:436 target_process_reset(): Timed out waiting for halt after reset

I tried everything, what i think it maybe helps. I changed FPC Cable, i checked the voltage source. Everything is fine!!!..

And i think it is impossible that i have a wrong armusbocd.cfg because i worked before !!!

Help me please!!!

Thank you…
