Hi Tiny,

It should not be a problem to use 'memcpy' after the SPI transaction. However, since it is causing a fault exception, I assume that either the destination pointer is invalid or you are overflowing the destination buffer. I recommend you debug the application and verify that the input arguments are correct.

Best regards,
