I just picked up a lpc2294l board, and have had trouble getting it to work. Any wise pointers are appreciated.
I’ve tried both openocd JTAG (olimex tiny usb A) and Flash Magic, and I don’t seem to get a good response. I successfully tested both flash magic and jtag with other arm7 devices, so I don’t think they are the problem. I also tried every combination of jumper settings.
Following the flash magic troubleshooting, I don’t get a response to typing U. Scope shows data coming in, nothing going out.
The OCD error messages (full list below)are:
Error: 52 141 jtag.c:1351 jtag_examine_chain(): JTAG communication failure, check connection, JTAG interface, target power etc.
Error: 53 141 jtag.c:1556 jtag_init_inner(): trying to validate configured JTAG chain anyway…
Debug: 54 141 jtag.c:326 jtag_call_event_callbacks(): jtag event: JTAG controller reset (TLR or TRST)
Debug: 55 141 jtag.c:1295 jtag_reset_callback(): -
Error: 56 141 jtag.c:1444 jtag_validate_chain(): Error validating JTAG scan chain, IR mismatch, scan returned 0x3f
The JTAG config is attached (from the olimex site)
The openocd listing is also attached.
Do I have a dead CPU?
Thanks in advance.
