jetson-nano 2Gb bootloader error

[Nathan Nérambourg]

Hello,

I have several problems with the image when I boot, first I have a DNS resolving problem, I could temporary solve this by adding nameserver 8.8.8 to /etc/resolv.conf

The other problem is with apt, I can't install packages or upgrade:

Errors were encountered while processing:
nvidia-l4t-bootloader
E: Sub-process /usr/bin/dpkg returned an error code (1)

I think it's because I have a 2GB Jetson card, I tried to find out how to modify the image to match my card but being not very experienced I didn't succeed.

From this link: https://docs.nvidia.com/jetson/l4t/index.html#page/Tegra%20Linux%20Driver%20Package%20Development%20Guide/quick_start.html#wwpID0E0EB0HA
There is the variable $ (BOARD) that changes to jetson-nano-2gb-devkit .

I don't know if this is the source of my problems, although I strongly suspect it.

Could you help me on this ?

For Jetson-nano 2GB, you need to edit the script create-image.sh in the line 54 and change it to from

./jetson-disk-image-creator.sh -o jetson.img -b jetson-nano -r 200

to

./jetson-disk-image-creator.sh -o jetson.img -b jetson-nano

Nvidia Docs here section Flashing to an SD Card

For the DNS, try to restart systemd-resolved

$ sudo systemctl restart systemd-resolved.service

It works, thank you! :)
It was :
./jetson-disk-image-creator.sh -o jetson.img -b jetson-nano-2gb-devkit

Unfortunately I still have the DNS problem after
$ sudo systemctl restart systemd-resolved.service
I looked into this : #15 but still I can't get it work

I got :

$ cat  /etc/systemd/resolved.conf

[Resolve]
DNS=1.1.1.1
FallbackDNS=8.8.8.8
#Domains=
LLMNR=no
MulticastDNS=no
DNSSEC=yes
DNSOverTLS=yes
Cache=yes
DNSStubListener=yes
ReadEtcHosts=yes

$cat /etc/resolv.conf 

nameserver 127.0.0.53
options edns0 trust-ad
search home

I'm gonna update the scripts to support Jetson Nano 2GB.
Meanwhile, you can follow these steps to solve the DNS issue

$ sudo systemctl stop systemd-resolved.service
$ sudo systemctl disable systemd-resolved.service
$ echo "nameserver 1.1.1.1" | sudo tee  /etc/resolv.conf
$ sudo chatrr +i /etc/resolv.conf

[Nathan Nérambourg]

I got this :

$ echo "nameserver 1.1.1.1" | sudo tee  /etc/resolv.conf
tee: /etc/resolv.conf : No such file or directory

But the file exist (in red with ls)

$ sudo chatrr +i /etc/resolv.conf
chattr: Opetation not supported while reading flags on /etc/resolv.conf

I really don't know what I did !

EDIT : $ sudo systemctl restart systemd-resolved.service
This work, but I need to do it after each reboot

[BADR]

You need to this

$ sudo chattr -i /etc/resolv.conf
$ sudo rm -rf /etc/resolv.conf
$ echo "nameserver 1.1.1.1" | sudo tee /etc/resolv.conf
$ sudo chattr +i /etc/resolv.conf

[Nathan Nérambourg]

It will fix it even when I reboot ?
I still got this :

$ sudo chattr -i /etc/resolv.conf
chattr: Operation not supported while reading flags on /etc/resolv.conf

It's normal ?

[BADR]

Try to remove it first

$ sudo rm -rf /etc/resolv.conf

[Nathan Nérambourg]

Yes the other line after this worked

[Nathan Nérambourg]

Ok nice it's working even after a reboot, thank you for your help :)

[BADR]

You're welcome :)
