[En-Nut-Discussion] Trunk 6420, how to set USART3 pin mapping on STM3240G?

[Michael Fischer]

Hello List,

I want to build the trunk 6420 but unfortunately the USART3 is set to PB10/PB11 
instead
of PC10/PC11. Here I use the stm3240g-eval.conf.

I have use Architecture / CM3 / STM32 Family / U(S)ART devices / STM32 USART3 Driver
but the "Use Alternate Pins" option is gray.

Best regards,
Michael
