My supplies from Moates arrived today, I removed the PCM, pulled the Memcal and made my first attempt at copying it. Question, do any offsets need to be specified in Flash N Burn to copy the memcal to the buffer to be able to save it as a file on the PC or only when burning the buffer to the chip ? When I copy it, the file shows 1 byte ?? All the instructions on Moates are very clear but I couldn't find anything regarding copying the memcal, only how to upload the saved file to buffer, then buffer to chip, then check chip against buffer to confirm complete burn.
