do you have an other stm32f4 board at hand (e.g. stm32f4discovery) to
confirm it's the same issue there? A scope or logic analyzer would be
useful to check if CLK and MOSI are running.
The general setups seems reasonable in general. In case the issue
persists please add a note to this issue where we collect leftovers from
recent SPI reworks in RIOT.
