Hi, I have some doubts. There is another feature to be implemented: The upgrade in field of the firmware. The bus used for this is the SPI, Maybe it will be the topic of another post. My question is: How to download the new program (knowing that the SPI send 8 bit at a time) keeping the MPU active, without overwriting the current firmware or stored data? After reset the Program counter has to point to the new program. Are some manual memory partitions necessary? Thank you very much for your support.
