I am trying to use USBDM to debug a custom board.
The board uses the MKL25Z128 processor, the same as on the FRDM-KL25Z board, however it is in the smaller 48 pin QFN package.
I've been able to go thought the debugging examples with USBDM on the FRDM board via KDS with no issues.
.
Alas when I try to use the FRDM board to debug the custom board I get "GDB Handler initialization failed, reason: ARM transaction Fault".
I can use the FDRM board to program the custom board flash with no issues so I feel the hardware is all talking okay?
Can someone point me in a direction to over come this transaction error please?
