Hi Igor,
Good find. Obviously I'd neglected to test SPI3 due to the pinout
conflict with the debug port. Using SPI3 relies on the user having
previously disabled the debug port in CYGHWR_HAL_STM32_AFIO_MAPR and I
was thinking it might be useful to add this information to the CDL
description for SPI3.
Do you have an FSF copyright assignment in place? If not, I can
generate a similar patch and submit it to the patches mailing list.
Chris.
