Hi ,
we have a custom board in which FPGA is communicating over PCIe.processor will be configured as ROOT COMPLEX and FPGA will be configured as END POINT.
We need to write the driver for the same.
We are using ti-processor-sdk-linux-am57xx-evm-04.01.00.06.
Since i am new in driver development,Currently I am studying PCIe Controller chapter of TRM.
Please suggest me any sample pcie driver which i should take it as reference and also DTS modification.
Regards,
Biswajit
Hi Rex,
Yes I want to communicate with FPGA over PCIE. In that Processor will be Root Complex and FPGA will be Endpoint.
So if i understood correctly then I need to write a misc driver as suggested example(drivers/misc/pci_endpoint_test.c) only .
Since am57xx-evm.dts(ti-processor-sdk-linux-am57xx-evm-04.01.00.06) doesn't have PCIE configuration for Root comple,If you can share the required modification in DTS file for processor as RC will be really helpful.We are using PCIE_TXP0,PCIE_TXN0,PCIE_RXP0,PCIE_RXN0.

HI Rex,
link ,but i didn't find any PIN connectivity information between RC & EP.
I have attached our schematic of pin diagram and let me know whether i need to any pin configuration or not.

Hi, Biswajit,
I am not sure how I can further help you here. If you have TI related issue, please submit a new thread.
Thanks!
