Re: Data Persistence Between Flashes

There is a high probability that your SD card has spontaneously and irrevocably gone Read Only. If that is the case, bin it and use a fresh one. To test. Write an empty or trivial file with a very obvious name . Check that it is there. Close down, power cycle and reboot. Is your test file still ther...
