Well, on my Olimex LPC-2378-STK board, I've seen similar messages after I
fed OpenOCD a configuration for another board. I had downloaded a project
for another board and was converting it to run. After trying to upload to
the wrong locations, it started spewing messages like yours. Resetting
everything didn't help and I thought my board was done for. I used the
FlashMagic thingy and was able to connect to the board thru the serial port.
After flashing it with the demo code from IAR, it started working thru the
JTAG again. Have no idea what was really wrong.

Thanks Michael.
Well, as you may have seen from a follow-up post I made, one of the
problems was a *bit* like that in that for the JTAGKey I had to comment
out the "jtag_reset" lines in the *.cfg file. I worked this out from my
cfg with the older openocd file that didn't have them. These lines do
seem OK for the ARM-USB-OCD though.
The main issue was I was experiencing multiple problems that all had
similar symptoms, so if I happened to fix any one of them, it didn't
seem to help.

Still dunno why the ARM-USB-OCD won't play with the 2148 though !
Weirdness. If I didn't have a "good" setup combination to start with,
I'd probably have despaired of ever getting the things going.

Cheers,
Bruce

Hmmm

All is still not fine with ARM-USB-OCD. For some reason I can't get it
to breakpoint on main reliably. I usually set a temporary breakpoint
there as part of the startup of gdb, but if I do this, it never gets
there. If I just let it halt at random when gdb starts, then I can put a
breakpoint on main and it can get there OK.
Is there an openocd guru who can tell me what I should do here instead ?

Here is my gdb startup:

target remote localhost:3333
monitor soft_reset_halt
monitor arm7_9 force_hw_bkpts enable
symbol-file bin/track.elf
thbreak main <- Have to remove this line and continue to get it to work
with ARM-USB-OCD.
continue

Cheers,
Bruce

Well, on my Olimex LPC-2378-STK board, I've seen similar messages after
I
fed OpenOCD a configuration for another board. I had downloaded a
project
for another board and was converting it to run. After trying to upload
to
the wrong locations, it started spewing messages like yours. Resetting
everything didn't help and I thought my board was done for. I used the
FlashMagic thingy and was able to connect to the board thru the serial
port.
After flashing it with the demo code from IAR, it started working thru
the
JTAG again. Have no idea what was really wrong.
