I've test the STM32F072 for using it in a new project. The configuration and libbrary are used from the CubeMX with the Keil compiler.

Now I can maximum transmit 4 bytes over the UART with one DMA transfer.

I'm not sure playing metoo with a single post participant is likely to get results.

I believe there are newer versions of the software mentioned, are there issues with those too? I'm not sure there are any intrinsic limits on the F0 parts doing DMA TX on the USART, are USART or DMA indicating any fault/error conditions?
