TDA4VM: How to use PCIe EP mode with SDK09_02_00

xi xiao

Part Number: TDA4VM

Hi expert,

Hardware platform:J721EXSOMG01EVM + J721EXCP01EVM

Trying to use PCIe EP mode according to 3.2.2.11. PCIe End Point — Processor SDK Linux for J721e Documentation, but at dts files can't find pcie0_ep node.

There is a pcie_rc node in the k3-j721e-main.dtsi file, but no pcie_ep node.

Is sdk09_02_00 support PCIe EP mode, what should I do to use PCIe EP mode.

Thanks, Best Regard!

Hi Xi,

We have made a patchset for putting back PCIe EP nodes, but through overlays here: https://lore.kernel.org/all/20231020113222.3161829-1-s-vadapalli@ti.com/

Please either apply this overlay, or reference the patch for enabling PCIe EP mode.

Regards,

Takuma
