I can easily believe that both of these don't quite work. I didn't do much testing in this area, so any changes to make it work are appreciated. > 3) I've now got full register maps for the AFIO, DMA and SPI blocks. > For development purposes I've kept these in a separate file from the > STM32 var_io.h, but can provide the file for merging if required.

You can mainly test polled operation in the kernel just by temporarily forcing the polled parameter to true. -- Nick Garnett eCos Kernel Architect eCosCentric Limited http://www.eCosCentric.com The eCos experts Barnwell House, Barnwell Drive, Cambridge, UK.
