Hello Petter,
After several hours of research, here is my conclusion:
- i was not able to find anybody with experience of firmware uploading via SPI
- i was not able to find anybody with experience of firmware uploading in production chain
- i was not able to find a software able to program SPI with size bigger than 32Kbytes
My conclusion is:
- i have the feeling i am the first to look for these above things
- i give up the SPI port
- i give up the idea of firmware uploading, from outside interface casing
- firmware uploading in production chain will be done via BDM port
Regards.
