Re: spi driver on at91


Hello,
I'm really interested to see your code, perhaps it wiil be a good starting
point, or perhaps just need a simple port to at91m42800.
What i want to do is "/dev/spi" type of driver wich can handle all type of AT91
board.
After make a dataFlash and ADC driver on it.

Regards
David
