TMS320C6654: Pcie transfer data between RC device and EP device

Hong Han

Part Number: TMS320C6654

Hello!

I run a project with PCIESS. When I run project with mode PHY Loopback, I can write data to addr 0x60000000 (Pcie space addr).

When I run C6654 as RC device, and FPGA as EP device. Link was up, I write data to addr 0x60000000 (Pcie space addr) on RC device, but value does not change, so data can't transfer to EP device.
Can you help me?

Thanks!

I can write to PCIe space, after I set mask for EP device in Remote config. Now, My problem is no any data on debug FPGA side. Did the data sent?

Hi,

Sorry for delayed response, Please refer the following link

https://www.ti.com/lit/an/sprabk8/sprabk8.pdf

In the document, follow example 5 and 6 and to check for the PCIe configuration in your code. Make sure PCIe works by connecting two EVMS with one set at RC mode and other set at EP mode.

Also compare EP configuration in FPGA with the example code (Register configuration).

Thanks & regards,
