"Use Alternate Pins" is a concept for STM32F1 where pin mapping is much more
inflexible against all newer STM32 families. F1 can only remap group of
pins, while all newer families can remap each pin individual.

So use the "USART3 xX Pin selection" drop-down list or map the pins direct in
the *.conf file. Is USART3 PC10/PC11 the default UART connection for debug?
Then perhaps stm3240g-eval.conf needs to be adapted. However PC10/11
eventually collides with D2/D3 of the MicroSD connector.

You can check the configuration result after the configure run in
include/cfg/uart.h or eventually edit manual there for a test.
