SPI Slave Boot Mode for BF506F - how to program internal flash

Question asked by BF506USER on Dec 2, 2011

I am looking to find the method/protocol I should use from my host processor to program BF506F internal flash over SPI bus.


1. Configure host processor to be SPI master.

2. Change boot mode (BMODE 100) on  BF506F.


Can you please help with the following questions:


1. What is the location of the BF506F RAM I need to use for writing as I just transmit one byte after other of the loader file?

2. Would I need a special firmware loader and a main loader since the code I need to program to internal flash is larger than RAM size?


Please let me know if this is not clear and I can provide more information.


Thanks a lot for any help!
