Hi,community:
When I configure LINFlexD in UART mode and use it with DMA, for UART TX mode, data can be transmitted normally, but for UART RX mode, data in UART FIFO (LINFLEXD. BRDM) cannot be transmitted to RAM normally through DMA. I configure the corresponding TCD and peripheral DMA request sources according to Tables 7-25 and 7-26 in MPC5777MRM, but UART RX DMA seems to have not been executed correctly, which has been bothering me for a long time, I hope you can help me, thank you very much!The attachment contains the corresponding source code and values in the registers.
