On most (all) STM nucleo boards we have a pin usage collision on pin PA05. It is used for both LED0 and SPI_DEV(0) sclk. Now after the SPI remodeling was merged, the SPI busses are for some boards now initialized before the LED pin, leading to an overridden pin config and a not working SPI clock line...

Now the question is how to proceed here.

@kaspar030: would you mind to check the pin configuration (MODER register) for your F334/encx24 setup quickly? Thx
