Kernel rebuild in jetson nano 2GB devkit

Yes

We are not checking on that way but if there is any possibility then we can check.

Because our test environment is pure source +ubuntu 16.04. So maybe you can check pure source first.

Honestly, this error is not serious if you just want to try a modem for your own use.

OK. then can we continue next steps with ignoring this error?

Yes, I think so.

Hi,

After this command “sudo make ARCH=arm64 O=$TEGRA_KERNEL_OUT modules_install \INSTALL_MOD_PATH=/Linux_for_Tegra/rootfs/”, how we can build image into jetson nano 2GB devkit?

Use flash.sh to flash the board again. The quick start guide from dlc should teach you how to use that.

What you were doing is build the kernel module and copy that to the rootfs. Rootfs is what going to be flashed into jetson.

Thank you.

We have done successfully generated kernel_supplicants.tbz2 using following command:
tar --owner root --group root -cjf kernel_supplements.tbz2 \lib/modules

Now we need to flashing the device again using flash.sh file. For that can you share any reference link or document.

Please search l4t quick start guide from below page.

Hi,

Can you verify the below steps for flashing the device.

  • sudo tar --owner root --group root -cjf kernel_supplements.tbz2 \lib/modules
  • cd …
  • sudo ./apply_binaries.sh
  • cd tools/
  • sudo -r …/rootfs/ ./jetson-disk-image-creator.sh -o quectel_sdk_nvidia_2gb_include1.img -b jetson-nano-2gb-devkit

After that generated image file load into the SD card using windiskmanager application.

No, this is not what we are talking about.

You don’t need to generate any sdcard image. After apply_binaries.sh is done, just use flash.sh.
Flash.sh will help install those things to your sdcard, you don’t need to pre-install anything to it.

Also, my previous comments told you how to use flash.sh.
