S32K3 Lpuart using DMA

[gaoweiguo]

    I refer to the S32K312_LPUART_DMA_EXAMPLE_RTD_LLD_100_34.zip attached to S32K344 UART DMA example

    But it can't send and receive data!! Please help me see what's wrong with this.

Hi,

if using LPUART3 then you should modify DMAMUX setting to select LPUART3 triggers for DMA, try below
