Enabling PCIE C7 & C9 with "gbe-uphy-config-9"

In my cutom board, I split the C7 PCIEx2 on the dev board into C7 PCIEx1 and C9 PCIEx1, I modified the ODMDATA = “gbe-uphy-config-9”.

I want to flash the bootloader first with command “sudo ./flash.sh -c bootloader/t186ref/cfg/flash_t234_qspi.xml --no-systemimg jetson-orin-nano-devkit external”.

Then make the Image with command “sudo BOARDID=3767 BOARDSKU=0003 ./tools/kernel_flash/l4t_initrd_flash.sh --no-flash --external-device nvme0n1p1 -c ./tools/kernel_flash/flash_l4t_external.xml jetson-orin-nano-devkit external”.

Then flash the system Image to NVMe with command “sudo ./tools/kernel_flash/l4t_initrd_flash.sh --flash-only --external-device nvme0n1p1 --direct sdb -c ./tools/kernel_flash/flash_l4t_external.xml jetson-orin-nano-devkit external”.

But after I flashed the bootloader, and to try boot UEFI without NVMe to check if it boots correctly, the UEFI can’t boot.

I only modified the ODMDATA, I don’t know if it has anything to do with direct full flash.

Please give me some suggestions, here is the device boot log.
