Hi Bill and Brandy,
Kontron does not give anything except for url to the latest f/w update. This does not help. They do not reply and are not intended to provide any help or fix. Terrible company and h/w.
So far, I provided a 3-wire connection of MMC to external connector in order to upload code using MSP430 on-chip bootloader via PC and will do the same to connect MSP430 UART to another connector in order to have run-time debug messages. I'm able to upload the MMC code and wonna modify MMC code to add DPRINTF() and putstr() diagnostic. This looks to take a very long time since at first I will need to understand the MMC code structure. The MMC code looks to be contributed by several persons and it always difficult to understand such a code.
Anyway thanks. I'm happy to hear any inputs to this threads.
