I am implementing a system with two STM32H753 microcontrollers. MCU1 reads ADC data and sends it over UART to MCU2 using UART DMA on ADC conversion. MCU2 reads data from UART via DMA and is supposed to do some filtering (among other things) to the received data. Earlier, all of the tasks were done by a single MCU (hence it was simpler, as we had access to the ADC data buffer already).
The issue I am facing is that the UART Receive DMA is never triggering the HAL_UART_RxCpltCallback() callback no matter what I do. I have tried the same with UART_Receive_IT() with no results either.
To help me ensure that it is not a configuration issue, I configured the same UART in a separate project (which is more of a simpler example of what I am trying to do) and verified my configuration to be working (posted about it earlier).
