How do I load an earlier version of the MX program? The current version does not generate code right like the previous version did.

Actually it is the plug in for the STM32CubeIDE that I am using. I need the code generator to work right.

Hello @KiptonM​ 

First let me thank you for having reported.

I created a little program with the CubeIDE 1.9 which activate the UART and the DMA and it generate correctly the code also I am able to send data with UART and DMA.

P.S I used an stm32h743 MCU.

Could you please precise on which MCU you have observed this misbehavior ?

Also, it will be helpful if you attach you .ioc file for further check from my side.

Thanks in advance.

Semer.

It worked on the STM32G031 but did not wok on the STM32G051K8T.

I found the error, that made me want to go back, it was not setting up the correct function for the Pin. It was Alternate Function 0 when it should have been Alternate Function 1 on the UART1 transmit pin. Receive was O,K, and I believe UART2 was O.K.

I could reproduce the same issue with older version from CubeMx.

Fortunately the latest version 6.6.1 generate the Init code with the right alternate function for the UART1_Tx.
