Re: [Openocd-development] LPC2148 JTAG Issues

It may not make a difference, but r717 is fairly old and many changes and fixes have been made in the meantime. Please try with the current SVN trunk as it includes more debugging information when run with 'debug_level 3'. Also, 'debug_level 3' should be the first line in your first config.

It doesn't appear that you've specified any JTAG taps. That _should_ be a hard error when init is run. It appears that OpenOCD is trying to validate
the chain anyway.
You'll need to add some lines to your config to describe the taps on the JTAG chain. Look at the target scripts included with OpenOCD for examples.
You may be able to use the stock LPC2148 target config.


I failed to mention that I did try that as well.  It failed in the
more complicated case, so I left that out.

Here's the command line I used:

openocd-ftd2xx -d 3 -f interface/arm-usb-ocd.cfg -f target/lpc2148.cfg

And the full debug output with both is attached at the end.  Lines 63
and 64 show the JTAG communications failure even with the target
script.

Even in this case, there is an JTAG communications failure.  I'm
convinced it is likely a hardware issue, and perhaps some ARM hardware
guru's are around that could suggest some debugging ideas.  And a
fresh pair of eyes on the schematic could help too.
