Transmission problem with UART7 and DMA on the STM32H743-Nucleo144 demoboard.

Hello everyone,

I am trying to transmit a string with the UART7 with the DMA on a STM32H743-NUCLEO144 demoboard, to do this I have shorted the pins PF6 and PF7 on the Morpho connector CN11 (short circuit between TX and RX of the UART7). I initialized the components and tried to send a string to DMA, but nothing is transmitted.

What did I do wrong?

I enclose complete project for Atollic 9.0.0.

Thank you
