How to flash Jetson 36.2.0 for endpoint mode agx orin

I want to flashing PCIe as Endpoint on a Jetson AGX Orin Series System. I follow the PCIe Endpoint Mode — NVIDIA Jetson Linux Developer Guide 1 documentation:

1.Add ODMDATA=“gbe-uphy-config-22,nvhs-uphy-config-1,hsio-uphy-config-0,gbe0-enable-10g,hsstp-lane-map-3”; in jetson-agx-orin-devkit.conf.

2.sudo ./flash.sh jetson-agx-orin-devkit mmcblk0p1

Wait about 30min， the flash message is：[ 686.1191 ] Flashing completed

[ 686.1192 ] Coldbooting the device

[ 686.1202 ] tegrarcm_v2 --chip 0x23 0 --ismb2

[ 686.1208 ] MB2 version 01.00.0000

[ 686.1491 ] Coldbooting the device

[ 686.1498 ] tegrarcm_v2 --chip 0x23 0 --reboot coldboot

[ 686.1504 ] MB2 version 01.00.0000

*** The target generic has been flashed successfully. ***

Reset the board to boot from internal eMMC.

But the orin can not boot, the serial is not work and no display. I reboot the orin, but not work. Could anybody help me?
