HDMI output is not working after flashing mass flash image

Hi, Nvidia

The HDMI output of Xavier NX 16G is not working after I used mass flash image to update it. But system can boot completely and the UART output is normal.

Below is my step:
Generate mfi image:

sudo BOARDID=3668 BOARDSKU=0003 FAB=301 BOARDREV=H.0 FUSELEVEL=fuselevel_production ROOTFS_AB=1 ./nvmassflashgen.sh -x 0x19 jetson-xavier-nx-devkit-emmc mmcblk0p1

Flash eMMC:

sudo ./nvmflash.sh

JetPack version: 32.7.1

Boot log from UART:
BootProcess_MassFlashImage.log (38.2 KB)

please try with


Hi WayneWWW,

It still don’t have HDMI output.


Could you try rel32.7.2? and is normal flash (flash.sh) working fine?

Hi WayneWWW,

I use BOARDID=3668 BOARDSKU=0003 FAB=100 BOARDREV=B.0 and L4T 32.7.2 version. The HDMI can output normally. What is the difference between 32.7.2 and 32.7.1 on HDMI function?

There is no different in HDMI, 32.7.2 only adds some security patch to bootloader.

Hi WayneWWW,

The massflash image(BOARDID=3668 BOARDSKU=0003 FAB=100 BOARDREV=B.0

)can be use on the Xavier NX 8G?

Why not you use online mode first and see what board sku and fab are in use?
