RTOS/AM5728: EDMA support in PCIe driver

Manjula KS

Part Number: AM5728

Tool/software: TI-RTOS

In the current scenario, the example code for PCIe with EDMA support we call the EDMA driver APIs from the application code.

Do we have the PCIe driver which does it from inside the PCIe driver api's

Hi,

PCIE and EDMA are two separate packages. The PCIE driver examples on AM572x are designed with test application can either use CPU or use EDMA to move the data. In the latter case, the test application calls EDMA driver API. PCIE driver itself doesn't contains the PCIE API. We don't have that.

The UART AND SPI drivers have the EDMA support.

Similarly if I have to implement EDMA support in PCIE, how should I start.

I have to implement pcieTransmit and pcieReceive using EDMA.

Want to know the complications involved in implementing edma support in pcie driver like the UART driver with edma.
