Strange SPI Behavior

[Giovanni]

Hi,

Are you running with the debug options activated? (those in chconf.h)

As general rule, when you have a problem in a complex system, reduce complexity and find the part that triggers the problem (disable everything and then reintroduce things one at time).

Yes, I'm running with all the DEBUG options activated.

I'm using that rule, deactivating everything and re-introducing the peripherals one by one... but still I don't understand what exactly goes wrong!
