Update our own orin board failed, but update the attached demo orin board success

There is sticker on your module.

Hi,
I thought that there is no DP output is because USB is otg, and I have modified the dtb and changed the mode of USB from otg to host. When I burned this dtb, the error "

ProcessExtLinuxConfig: Failed to open file: Not Found
L4TLauncher: Unable to process extlinux config: Not Found

"appeared.
If I don’t modify the dtb, the module can be burned successfully and bringed up successfully.
But there is a problem there is no DP output after log appeared when the debug serial reached at login step.Do you have any suggestion?

The following is the last section of bringup.

May I know how you update this dtb? I mean the steps.

Hi,
First, decode the dtb
dtc -I dtb -O dts *.dtb > tmp.dtsi
Then, modify the dtsi, and encode the dtsi
dtc -I dts -O dtb tmp.dtsi > *.dtb
Last, use flash.sh to burn the module.
Thanks

Where do you put this dtb to? What dtb is in use? Could you specific the file name?
And how did you flash the module?

I put it in “Linux_for_Tegra/kernel/dtb”.
The used dtb is tegra234-p3701-0004-p3737-0000.dtb.
The flash cmd is “sudo ./flash.sh jetson-agx-orin-devkit mmcblk0p1”

So your actual command to update dtb is

dtc -I dtb -O dts tegra234-p3701-0004-p3737-0000.dtb > tmp.dtsi

Like this?

Yes

If you don’t change any content in the dtb but directly change it from dtb → dts and then dtb, will you hit this error?

If I do as you say, there is no error hited.

Hi,
I retry the dtb which is modified from otg to host, and the module can be brought up successfully.
But there is a problem that the DP has no output after the picture of log appeared for a little time.

Hi,WayneWWW
Do you have any suggestion?
Thanks

If you can flash the board now, please file a new topic.
