TX failing on UART7 (STM32F469)  Topic is solved

Postby josesimoes » Mon Apr 08, 2019 4:43 pm

Hi,

I was testing the recently added support for UART7 in STM32F4 and I can't seem to TX anything on UART7.
I've double checked the pin assingments in board.h they are correct, including setting of AF to 8.
I've double checked the buffers and they are OK. DMA channel assingment too.

Ultimate test was to switch my code to use UART6 instead of 7 and it's working as expected.

Can anyone validate this please?
Thanks,

Hi,

Found the problem: STM32_UART7_RX_DMA_CHN is mapped on channel 4 instead of channel 5.
