NUCLEO-F767ZI UART3 TX DMA NOT WORKING

AAoe.1 · ‎2019-12-21

I've created a new project just to send a string over UART3 TX via DMA. The non-DMA version workes fine...so I'm not sure what I'm doing wrong here. I think I had configured the cube correctly...so I'm stuck. Can someone help me take a look at the attached files please!?!?

Thank you

The cube is known to generate buggy code if DMA is involved. Something like wrong initialization order, but I'm not using it.

Hello,

It should be the same issue as the ones listed in this discussion: https://community.st.com/s/question/0D50X0000Bmob3uSQA/dma-not-working-in-cubemx-generated-code-order-of-initialization.

This will be fixed in next release of STM32CubeMX.
