I tried hbreak instead of break, and it worked. I'm using the configuration file "xmc4800-relax.cfg" which refers to "xmc4xxx.cfg", both from OpenOCD. How can I define the flash range correctly?
I found in "xmc4xxx.cfg" line 54: flash bank $_FLASHNAME xmc4xxx 0x0C000000 0 0 0 $_TARGETNAME But I don't have a clue how to fix it. Thanks a lot!
