I would like to reprogramming the MCU MCF51AG128 via SPI. Actually i use the BDM Port but in my application the SPI bus is only available for reprogramming the MCU.
Is there a sofware for programming via serial port SPI.
If i need to make a software, do you known the sequence for programming via SPI?
For exemple :
- Enable/configure SPI port in the first programme via BDM port then you can communicate via SPI
- Reset MCU (through software or hardware ?)
- Change some registers in Flash memory (clock between 150 kHz and 200kHz, protection...)
- erase Memory
- Program ( transfert .elf file...)
- another reset ?
thanks in advance,
