Well done Burns!
Have we decided what the best method will be to read and write a file to the MRAM? To simplify things we could assume files do not change size after writing, except the telemetry where we can preallocate the required size. For other files we must always receive the header first, which holds the file size.

Below is the console output from the current software. "test mram" writes the address into every 4-byte MRAM cell from 0 to 1MB and then reads it back to check. Believe me, I've had plenty of cases where it does not match and it printed it out. (It was essentially always my error!)
