Re: Wiggler + Crossworks works, ocdremote not?

2004-12-06 by digtalfreak

Make sure that there is no programm running in the flash. I also
sometimes have problems using ocdlibremote when there is a working
programm in flash that uses interupts. So make sure you are in
bootloader mode (holding down P0.14 while reset or simply erase the
flash and then reset).

- do a reset (into bootlaoder mode)
- start ocdlibremote
- start insight/gdb
- load programm
- download programm (remote/tcp, localhost, 8888)
- then use "continue" to run the programm, don't use run (that cut's
of the ocdlib connection at my computer)

I wrote a little batch that restarts ocdlibremote if it is shut down
by connection loss.

:LOOP
ocdlibremote -c ARM7 -d WIGGLER -a 1 -s 1
GOTO LOOP
