i.MX6Q PCIe EP/RC Validation System

I want to use above method for verify my pcie bus. but I have only one sambasd board. So I use a fpga as EP.

sambasd board(RC mode)<------>fpga(EP mode)

but I find pcie.c have define EP_SELF_IO_TEST, this is only used for EP mode.

Now I want to use EP_SELF_IO_TEST in RC mode ,Can you tell me how to change? thanks!

Hi mingming

on that link one board is used in RC mode and you can use

its settings

When building RC image, make sure that

        CONFIG_IMX_PCIE=y

        # CONFIG_IMX_PCIE_EP_MODE_IN_EP_RC_SYS is not set

        CONFIG_IMX_PCIE_RC_MODE_IN_EP_RC_SYS=y

Best regards

igor
