Hi,

I suspect this may be related to different pinout on your custom board. Please check the error information passed to app_error_fault_handler() ->app_error_save_and_stop() , is should include the error code, and where in the code it occurred. Note that project must be re-compiled with DEBUG flag set in order for the program to reach app_error_save_and_stop().

Hi Berg

Debug picture as follow，but i do not know what do it mean,do you know it?

It's important that you let the program reach the while loop at line ~138 before you read  out the memory. Also forgot to add earlier that you should build your project with code optimization disabled.
