I'm unable to get emulator to connect to the frdm-kl25z. I'm using j-link emulator. I have cut the trace on J11 as instructed. The debugging via openSDA works ok. When I try to connect with Segger J-Flash (target->connect) it says "failed to connect". Similar thing happend when I try start debugging in IAR.
Hello,
why did you cut J11? This is only needed if you want to use the FRDM board to debug *another* board, see Using the Freedom Board as SWD Programmer | MCU on Eclipse .
To debug the KL25Z on the FRDM-KL25Z using the SWD connector, all what you ahve to do is to add that connector, nothing else.
I hope this helps,
Erich
