Hi,
I'm using a STM32H7S78-DK board along with stm32cudeide 1.16.0. I'm loading the example LTDC_ColorKeyring which work fine, here is the issue... I'm trying to implement uart4 connected to the onboard ST-link. If I init MX_UART4_Init() and use HAL_UART_Transmit(), BEFORE MX_LTDC_Init(), it work fine. As soon as the LTDC is init, I cannot use the Uart at all. I don't see any pin conflict here... the uart4_tx is PD1 and is only connect to the VCP of the st-link.
I'm evaluating the STM32H7S for business, but if I cannot get those two simple peripheral working together...thats a big flaw
