Jetpack 34.1 Kernel 5.10 Flashing hangs

Ok. Ignore my previous comment then.

I’m having exactly same issue here. I found that it only happens if I flash with a modified dtb to start with. So I did the following to make it work:

  • First flash with default dtb without any changes.
  • Then, modify the /boot/extlinux/extlinux.conf by removing the line FDT /boot/dtb/kernel_tegra194-p3668-0001-p3509-0000.dtb. I also create a backup boot options just in case.
  • Then cp "$BUILD_OUT/arch/arm64/boot/dts/nvidia/"*.* "$L4T/kernel/dtb/"
  • Flash the correct customized kernel-dtbsudo ./ -k kernel-dtb jetson-xavier-nx-devkit mmcblk0p1.
  • Then, reboot new dtb will be in effect .

This works every time for me.
