How to modify a jetson nano image file with pre-installed custom software！ backed up the system files using the “dump” method. I restored it on a 128G TF card, and it failed to boot. Nothing happened, but it returned to normal on a 64G TF card. Is there any way to solve this problem? Both 128G TF c…

My suggestion would not be to back up what you have wholesale, rather to backup up the difference between the stock image and what you have and apply that to the rootfs. If you backup a system after first boot, many things like the host ssh keys, hostname, etc, which you normally want to be unique, …

Can you post/pm a script or some sort of log of the exact steps you ran (especially within the chroot). This is a reason I suggested a script might be useful. I will try to replicate and fix. My feeling is that this all revolves around the user creation. Even those commands alone would be useful to…

After First of all thank you for your reply, I am here to re-create the image file, there is no recurring problem. It may be that I used incorrect instructions after using “enter_chroot.sh”, which caused this situation.

I used sdkmanager to download all the nano files, but how to install these in the image file. For example, cuda, tensorrt, cudnn. I thought I used enter_chroot.sh, then dpkg -i …, and it didn’t feel right

After First of all thank you for your reply, I am here to re-create the image file, there is no recurring problem. It may be that I used incorrect instructions after using “enter_chroot.sh”, which caused this situation. Possibly. What commands did you run within the chroot? Your problems seems t…

Edit: updated post after testing: If you are using JetPack 4.3, you can use apt-get to install those packages from within the chroot. All many of their package names start with “nvidia”. You will have to edit rootfs/etc/apt/sources.list.d/nvidia-l4t-apt-source.list to match the following for Nan…

I did some tests myself, and it seems some packages are not prefixed by “nvidia…”. Deepstream 4.0 can be installed within the chroot after setting up the sources like: apt install deepstream-4.0 TensorRT seems to be “tensorrt” so: apt install tensorrt You can use “apt list” with wildcards as s…

So I googled , and this is the way you can find a list of all the packages (from within the chroot): root@hostname:/# grep ^Package /var/lib/apt/lists/repo.download.nvidia.com_jetson_t210_dists_r32_main_binary-arm64_Packages | awk '{print $2}' | sort -u graphsurgeon-tf jetson-gpio-common libnvinfer6…

So, I just booted the system after installing deepstream, tensor_rt, and a bunch of other stuff. First boot scripts executed as intended and I’m left with a system that requires no updates and already has all the stuff I want installed. Neat. If you run into any difficulties, don’t hesitate to ask.

hi mdegans, i folllowwed your steps and stuck at installaing cuda, tensorrt, cudnn. I also added in rootfs/etc/apt/sources.list.d/nvidia-l4t-apt-source.list to: deb https://repo.download.nvidia.com/jetson/common r32 main deb https://repo.download.nvidia.com/jetson/t210 r32 main after that i ran…

Hi, thohtdelta, Nvidia’s online repos probably only work with 4.3 and up. Nvidia’s key is not installed on 4.2 rootfs and even if it was, it would probably break things.
