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.

You need to modify the device tree.
See the discussion over
Hi WayneWWW
Thanks for your prompt reply.
You mean modify the MB1 Pinmux and gpio dtsi？I tried the following changes and pointed to the generated device tree in jetson-orin-nano-devkit.conf
But it doesn’t work, the result is the same as the log above.
No, I mean the kernel device tree. Read the post and try to understand what we are doing there…
I forget to replace the build dtb file in kernel before flash bootloader.
The C7 & C9 work now, thank you.
@EEEXcalibur please kindly share your device tree here as a record and we can close this topic. Thanks.
OK
I use p3509-a02+p3767-0000 as my orin nano module+cutom board configuration.
I enable C7 & C9 with modified the tegra234-p3509-a02-pice.dtsi, then re-build the kernel.
Here is my build tegra234-p3767-0003-p3509-a02.dtb file

Can you please share the dtsi file? I have encountered the same problem…
