STM32F7 StEmWin CMSIS + USART DMA Issue

Hi,

I have a small code for for UART7 Rx DMA circular buffer and Tx DMA normal buffer, this code runs normal with a basic setup generated using CubeMX.

 

Once i am adding the code in in LCD application running CMSIS on a GUI thread, the UART DMA code doesn't run as expected.

I have created a new thread for the UART DMA with normal/high priority and 1024bytes for stack, the behavior is better but still unreliable.

Does anyone can help me on how to set up CMSIS in order to have the UART DMA work in a reliable way?

 

Thank you
