How to use eDMA receive Interrupt ?

dearwww2000 — Mon, 16 Mar 2020 03:46:50 GMT

LPUART configuration is :

Transfer type select DMA , Baudrate is 500000 , RX use DMA channel 1, TX use DMA channel 0.

eDMA configuration is :

two DMA channel : channel 0 request is LPUART0_TX, channel 1 request is LPUART0_RX.

SW code is :

Use “LPUART_DRV_ReceiveData(INST_LPUART0, (UINT8 *)DataBuf, DataLen)” to receive UART data.

But the SW can’t run to LPUART_DRV_RxIrqHandler().

SW can go to “LPUART_DRV_TxCompleteIrqHandler()” when use “LPUART_DRV_SendData(INST_LPUART0, (UINT8 *)DataBuf, DataLen)” to send UART data.
