Hi, I bought a new FRDM-K64F board, but I've same problems with OpenSDAv2 Debug.
The default bootloader installed is MBED but it has several connection problems and often crashes
whit the following error:
"crt_emu_cm_redlink has stopped working mcuxpresso "
Hi
Continue using the Segger OpenSDA since it is basically good.
Probably the error is because you are loading code with Flash configuration values (in 0x400..0x40f range) which have values that it doesn't like. For example, the values may cause the chips to disable its debug interface and become secured, which the loader will try to protect against.
Try loading some binary file from here
http://www.utasker.com/kinetis/FRDM-K64F.html
because these will have good values and so identify whether it is due to the *.bin that you are trying to load or not.
Regards
Mark
