Hello Kevin, please try the following:
use openocd release 0.1.0 so we can see if we have the same problems or not, use the lpc2468.cfg that I send you or send me your cfg file use following command line: ./src/openocd -f src/target/interface/openocd-usb.cfg src/target/target/lpc2468.cfg if doesn't work what i always do is flash a small example programm which is comming in the olimex cd, after that program I can always have contact over the debugger, at least until a hard reset. I have no idea why, i have the problems since ever but I am not an openocd expert :( or send me exactly what you are doing and I can try to generate the same scenario on my board. best regards, Mariano.- On Sun, Mar 15, 2009 at 12:26 AM, Kevin Townsend <[email protected]> wrote: > I just sat down to give it another shot, but I'm still really scratching my > head > at why I can't properly connect to the lpc2478 board with my ARM-USB-OCD.
