So the 10MHz is a safe value I guess. But I was wondering most why the bus speed seems to be limited to ~12MHz. Is that a limitation of the at91sam9g20 or more likely a problem with the board design?

you mean it defaults to 10 MHz. boards can freely pick anything they want. some speed needed to be arbitrarily picked, and 10 MHz should work with every spi flash out there. -mike
