STMG0 UART DMA Tx/Rx

[ItamarEliakim-R]

Description

Feature Request:
I am trying to implement UART DMA TX/RX for the STM32G0B1.
For some reason, the DMA doesn't trigger the DMA callback functions.

HAL_UART_RxCpltCallback

Or

DMA1_Ch4_7_DMA2_Ch1_5_DMAMUX1_OVR_IRQHandler

Usage example

Minimal example of STM32G0B1, using STM32CubeMX.
With TX/RX DMA enabled on UART1/UART2.

Additional information

Under certain infrastructure modifications, I see that the IRQ is triggered for the RX functions, meaning that the

USART1_IRQHandler

Is triggered properly.
The issues arise when working/testing the DMA functions, which are defined by startup_stm32g0xx.s.

Do you plan to address this issue and file a PR?

Yes

Hi @ItamarEliakim-R, thanks for opening the issue.

Could you create a CI setup based on our reproduction template?

We provide a support for STM32 DMA controller models in Renode already, so it might be a matter of properly configuring the platform.
