DMA to UART TX , code works on NUCLEO STM32H743 but not DISCO STM32H745
On both boards the UART/DMA in CubeMX is setup the same, with a DMA channel added for "USART3_TX". Comparing the generated USART and DMA initialization code, they are identical.However, with the NUCLEO board, it transmits with either "HAL_UART_Tran...
