DRIVE OS Version: 6.0.10

Issue Description: Understanding the hierarchy to rebuild the targetfs and binding the filesystem with yocto project

Dear NVIDIA Team, please consider this thread in regard to understand the build process and flashing the filesystem back to the target device

So far so, from the manual : DRIVE OS Linux Yocto Components | NVIDIA Docs

It seems like to rebuild the flash-able image, we would need the `tegra-drive-os-av-image` to be used with bitbake recipies in a certain variant (full; minimal; samples; and debug-utils).

What our intention is to be get a upgraded version of the `tegra-drive-os-av-image`, and then proceed with flashing this image with the bootburn without disturbing other partitions, and this is done by the `NVIDIA Build-Fs` ?

Upon reading the manual again, the `NVIDIA Build-Fs` seeks a base ubuntu image in deb format and the other resources as optional ? (like getting the deb files for CuDNN, CUDA, TensorRT) :

  1. The NVIDIA Build-Fs needs a config manifest in json format to gather the mirrors and the base filesystem to build it altogether? and thus results in targetfs.img? this is then a linker to `tegra-drive-os-av-image`?

If the above reasoning is correct;

  1. Can the base Ubuntu image (nv-driveos-linux-ubuntu-20.04-base-*_amd64.deb) be replaced with a different base image and then following with `NVIDIA Build-Fs` with an updated manifest?

Dear @SivaRamaKrishnaNV can I please get some guidance here? I believe I cant access any other version of nv-driveos-linux-ubuntu-20.04-base-*_amd64.deb package because DriveOS 6.0.10 was primarily made for Ubuntu20.04, however for a minimal build can the base image be repacked with Ubuntu22.04?

Hi @ashwin.nanda ,
however for a minimal build can the base image be repacked with Ubuntu22.04?

Let me check the feasibility with engineering team and update you.

Dear @ashwin.nanda ,
Only ubuntu 20.04 is supported on DOS 6.x.

dear @SivaRamaKrishnaNV, thanks for reaching back, I still need confirmation on the build process, I intend to repack the base image from my side, please confirm the reasoning on the build-process, and I shall close this topic.

You mean nv-driveos-linux-ubuntu-20.04-base image ? You can not use any other image than this.

8

I intend to open the deb package and repack it, even it leads to a failure of build; all I want is to please confirm on the reasoning of the build process, much appreciated, thanks.

dear @SivaRamaKrishnaNV please let me know if ive got his wrongly understood, you may close this topic if this seems logically correct you, awaiting.. :
