Hello Peter and list, I might be looking into completely wrong direction in this case, but it is worth noting that when I was experimenting with LPC2148 with OpenOCD, If found out, that LPC needs reset pulled while RTCK is low. At least from what I've seen, it seemed to me that power-on reset is not sufficient for this. It might be that RTCK is latched upon reset, not sure about what is going on inside.
Please have a look into the lpc2148.cfg, there is still note about this, but the following lines I have added jtag_reset 1 1 jtag_reset 0 0 are gone, I assume that it did not work for someone that way or influenced reset configuration etc. This was before JIM TCL integration, so I am not sure whether these to lines would still do the desired job. Please see following links: http://www.mail-archive.com/[email protected]/msg00604.html http://www.embeddedrelated.com/groups/lpc2000/show/36295.php You may also try pulling reset by a jumper by hand before running OpenOCD, just experiment with this and let the list know about the results, please.
