AWS F1: CL Controlling XDMA in Shell

0

Hi there,

Is there a way that CL can control the XDMA inside the Shell in the AWS F1? I have a usecase where CL needs to setup a DMA transfer from internal memory to Host.

A separate question, Is there a way CL can DMA from internal memory to DDR4 in shell?

Hi,

You can use the following function to do the transaction from CL to HOST.

*int fpga_dma_burst_read(int fd, uint8_t buffer, size_t xfer_sz, size_t address);

Also if you want to do DMA inside the CL, You may use AXI Multi Channel DMA IP. You can get from add IP or from IP Catalog.

Thank you
