Burning the prebuilt Image to upgrade Jetson Nano and Xavier NX Devkit
This method is no longer recommended because in this mode, the DTB partition reverts to the default value in some cases. It is recommended to use pre-compiled Image and DTB for driver upgrade.

@veye_xumm Hi, have testes 4.3 img and all is ok, imx327 works fine.
But system wants software update and after restart i can't see /dev/video0.
Tell me please, where i can get new 4.5.1 img?
Can i do apt upgrade, apt dist-upgrade?
Or how i can fix camera disappearing now?

Best regards, Viktor.

@veye_xumm Hi, have tried.
cat /etc/nv_tegra_release -> r32, 4.4
Download Image and dtb.
Copy to /boot
Edit /boot/extlinux/extlinux.conf -> FDT /boot/dtb file

And now i have nvidia logo only and loop reboot.

My system nano b01, imx327.

Updated: mount sd to host and removed line from extlinux.conf
Now it is bootable, but camera does not work.

Also i see initrd.img->initrd.img-4.9.140-tegra in /boot

Here is kern.log: cam360.tv/etc/kern.log

Please help.

Viktor

@veye_xumm I also have tried from host:
copy dtb to kernel/dtb
sudo ./flash.sh -r -k DTB jetson-nano-qspi-sd mmcblk0p1
from L4T but nothing, /dev/video0 is not present.

About system:

cat /etc/nv_tegra_release
R32 (release), REVISION: 4.4, GCID: 23942405, BOARD: t210ref, EABI: aarch64, DATE: Fri Oct 16 19:44:43 UTC 2020

number@number:~$ dpkg-query --show nvidia-l4t-core
nvidia-l4t-core 32.4.4-20201016124427

Bsp from here:
https://github.com/veyeimaging/nvidia_jetson_veye_bsp/tree/master/Nano/JetPack_4.4.1_Linux_JETSON_NANO_DEVKIT/dts dtb/VEYE-MIPI-327
Kernel from here:
https://github.com/veyeimaging/nvidia_jetson_veye_bsp/blob/master/kernel_image/Image_l4t_r32.4.4_veyecam.tar.gz

So, please tell me how to repair Veye327 system after ubuntu software update?

Viktor

@veye_xumm Here is screenshot, after fresh installation, ubuntu wants 600mb updates, include nvidia l4t4.4: cam360.tv/etc/43-44.jpg

So i need to update system without reflash as on other native jetson platforms.

Please help.

@viktor
If you want to upgrade new version of L4T, I suggest you upgrade the system first, then do our VEYE bsp upgrade.
This is the list of version we provide:

Jetpack4.2.2,L4T r32.2.1
Jetpack4.3,L4T r32.3.1
Jetpack4.4,L4T r32.4.3
Jetpack4.4.1,L4T r32.4.4
Jetpack4.5,L4T r32.5
Jetpack4.5.1,L4T r32.5.1

Please check the dtb file name and the line you add in /boot/extlinux/extlinux.conf, they must be the same.

@veye_xumm

Have build 4.5.1 from scratch and it works.

About upgrade.
Can i apply VEYE image/drivers without reflash and changing /app/home partition?

@veye_xumm Yes. It was first method what i did, but it does not work for Nano. Fdt line brokes system.

veye_xumm

@viktor
pls paste your fdt line here. It must be wrong.

Viktor

@veye_xumm

It was:

FDT /boot/tegra210-p3448-0000-p3449-0000-b00.dtb

It must works?

veye_xumm

@viktor
I think this line is correct.
It's very strange. It works normally in my place.

Viktor

@veye_xumm ok. Will try again.
