Enable C7 as RP for NVMe x4

Mar 04, 2024

Hello

We are working on a custom board for Orin which runs C5 in endpoint and C7 to a M.2 connection for an NVME. When enabling the C7 RP in DTB (pcie@141e0000) we see the error below and the NVMe fails to be detected.


7.660780] tegra194-pcie 141e0000.pcie: Failed to find PHY entries: -22     
[ 7.667696] tegra194-pcie 141e0000.pcie: Failed to parse device tree: -22
[ 7.674710] tegra194-pcie: probe of 141e0000.pcie failed with error -22

We are flashing with ODMDATA Config 2 but with nvhs-uphy set to EP.:

ODMDATA="gbe-uphy-config-0,hsstp-lane-map-3,nvhs-uphy-config-1,hsio-uphy-config-16

****Note: there is no networking devices on this board.

Is there something we are missing in the DTB?
