BUG in STM32CubeMX: usart code generation in wrong order when enable usart dma

Seldon · ‎2022-04-29

My Firmware Package name and version: STM32Cube FW_F1 v1.8.4

Bug detail:

After code generates, the code order is:In this order, receiving message of the usart will get some bugs, eg: only can receive the last byte...

I let `the MX_DMA_Init();` become the first one solve the problem, but when I genearted code next time, this order will appear again...

Hi @晓栋 �?� ,

This is a known issue that should be fixed for new generated projects (from scratch) using STM32CubeMX 6.5.0.

In case you are importig an old project, please refer to this content MX_DMA_Init order in the main.c file generated by STM32CubeMX, How to fix?
