Hi,
I tried to update NX’s device tree but failed,What went wrong, please.
sudo ./flash.sh -r -k kernel-dtb jetson-xavier-nx-devkit-emmc mmcblk0p1

 sudo ./flash.sh -r -k kernel-dtb jetson-xavier-nx-devkit-emmc mmcblk0p1

Is this your first time flashing the board using this directory?

541449841 · February 18, 2022, 5:33am

Yes.it is.
Is there any difference in between the NX and Nano?

WayneWWW · February 18, 2022, 5:34am

Try full flash first without -r -k kernel-dtb.

WayneWWW · February 18, 2022, 5:35am

And NX and Nano use different SoC. Totally different.

541449841 · February 18, 2022, 5:54am

Sorry,I didn’t make myself clear.I mean if I want update device tree only ,Is there any difference operation in NX and Nano.
First,compiling device tree
Second, copy DTB file "tegra194-p3668-all-p3509-0000.dtb"to …/…/…/Linux_for_Tegra/kernel/dtb
Finally,use this command to flash:sudo ./flash.sh -r -k kernel-dtb jetson-xavier-nx-devkit-emmc mmcblk0p1.

Try full flash first without -r -k kernel-dtb.

I’ll try it if there’s no other way.Thank you for your advice.

541449841 · February 18, 2022, 6:00am

The log shows can not find the file: tegra194-mb1-bct-ratchet-p3668.cfg .Is there any way to fix it? Appreciate for your any suggestion.

WayneWWW · February 18, 2022, 6:02am

Full flash will copy the file to that location.

541449841 · February 20, 2022, 1:12pm

Thank you for your reply,I flashed it successfully with this command:

sudo ./flash.sh -k kernel-dtb jetson-xavier-nx-devkit-emmc mmcblk0p1

NO -r , It works.
