Nano boot fails(kernel panic)

[kevinyeah00]

Thank you very much for the image!
I used balenaEtcher to flash this image to a 128GB SD Card, but I can't boot my Jetson Nano B01 4GB, it shows:

and reboot endlessly...

Could you give me some suggestions about it?
It would be nice if you provide the md5sum of this image, then I can see if I had trouble downloading the image.

[Qengineering]

See if this helps you: JetsonNano.zip md5sum: d186a59a0b4d95a3bb9a327feabbfa25

[dmvoro]

I ve got the same problem on my 3 sd cards. Maybe something went wrong with the image?
I checked md5 of an image - its wrong - 1e8ad1525cad58f920ae63df47901b2c

[kevinyeah00]

I downloaded the image again and this time it worked, It should be about 31GB, my md5 is 1e8ad1525cad58f920ae63df47901b2c, just the same as yours ,but it works. Maybe there's something wrong with your card reader?

[DeerLickObservatory]

Hi!
I ran into this issue as well, same log and reboot cycle. I re-flashed twice before checking here.
Here's my file's md5:

bucky ~ % md5 Jetson\ Nano/JetsonNano.img 
MD5 ( ~/Jetson Nano/JetsonNano.img) = 0e928f21c3e536e4461aaf00087ebfe6

bucky ~ % md5 Jetson\ Nano/JetsonNano.zip 
MD5 (~/Jetson Nano/JetsonNano.zip) = d186a59a0b4d95a3bb9a327feabbfa25

My .zip file matched the author's expected md5, but the unzipped didn't--and thats when I thought to try just dragging the .zip file into balenaEtcher, instead of the unzipped .img

After flashing, the Jetson Nano boots successfully. Can anyone else confirm if they were trying to write the .img or the .zip? balenaEtcher will successfully take and write both, but it seems only the .zip one produces a bootable system.

[turowicz]

Same problem here booting from 256GB USB stick. It is in a reboot loop cycle until it finally boots up. Must try different USB sticks.

I am using the Jetson Mate carrier board and Xavier NX (production).

[alana314]

Thanks for this image! I couldn't get the .img.xz file to work with balenaEtcher, but it did work with Pi Imager.

[garvitkhera]

Thanks for this image! I couldn't get the .img.xz file to work with balenaEtcher, but it did work with Pi Imager.

Same!!

[taothienpeter]

Help! I tried to flash it with both Pi imager and balenaEtcher, but nothing works

I tried to check for the MD5, SHA-1 from the downloaded file

• MD5: d738f1fe20088a1bdbd10e2358b512f7
• SHA-1: b5ca8b13031478b75b2faef366f193bcf0c31728
  and it does not match the ones you guys have. Also, the image did not come with its MD5 so I can't check from the source
  Im working with the jetson nano Dev kit 4Gb and try to boot it with Ubuntu 20.04 for ROS2

[Qengineering]

We apologize for the inconvenience. At the moment Sync has serious server issues. Pleas try to download later again.

We apologize for the inconvenience. At the moment Sync has serious server issues. Pleas try to download later again. (Qengineering/Jetson-Nano-Ubuntu-20-image#92)

is it still the same md5sum (d186a59a0b4d95a3bb9a327feabbfa25) as above?

[Qengineering]

The md5sum of JetsonNano.img.xz : 621F2E4E0B7775E5293E2186C96E91AA
Please note, it is the img.xz download, not the old *.zip one.

[osamaabdelatif]

I have downloaded the image couple of times, but never managed to get the same md5sum mentioned above, nor having it booting on the Jetson Nano.

[Qengineering]

To be sure, I downloaded the image myself from the Sync fileserver and checked its md5sum. It should work:

[rishikoushikz]

i too have the same problem i download it now

[osamaabdelatif]

Again i test another download today and i am getting the same reported by @rishikoushikz

[Qengineering]

Your download has the correct MD5 sum.
Please see: Qengineering/Jetson-Nano-Ubuntu-20-image#96 (comment)

[osamaabdelatif]

Thank you for confirming the MD5 sum, since it's the correct image, after writing it using balenaEtcher. the device isn't booting. i am getting below screen.

[Qengineering]

Did you see also Qengineering/Jetson-Nano-Ubuntu-20-image#96 (comment)?

[osamaabdelatif]

Hi, yes i saw the comment and actually tried both balenaEtcher and Raspberry Pi Imager both didn't work.

[Qengineering]

Still, it boils down on a hardware issue with you card. Your download is good. Your Jetson Nano is good.
BTW, you erased the SD card before flashing? Not just a quick format.

[osamaabdelatif]

I have formatted the SSD with 7 security-check to ensure it's totally erased, still same issue.
even used another brand new SSD for that and didn't work either. Not sure if someone test to write this image recently and boot Jetson Nano from it.

[osamaabdelatif]

I check the SSD image after writing on another system,
sudo fsck /dev/sdb

The superblock could not be read or does not describe a valid ext2/ext3/ext4 filesystem. If the device is valid and it really contains an ext2/ext3/ext4 filesystem (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with an alternate superblock:

[Qengineering]

I did test the image myself a few days ago. Everything just fine, no problem.
Did I read it right? SSD? It works only with an SD card.
For an SSD version, please look at Qengineering/Jetson-Nano-Ubuntu-20-image#32, and other related issues.

[osamaabdelatif]

it's SD card, ScanDisk. i am trying all option to get that image work in a boot way. is there any thing missing?

[Qengineering]

Can you flash the SD card with a regular Jetpack Nano OS. And does it boot?
Once again, I've tested it, and it works like a charm. Somehow your image isn't flashed correctly.
The The superblock could not be read or does not describe a valid ext2/ext3/ext4 filesystem. If the device is valid and it really contains an ext2/ext3/ext4 filesystem (and not swap or ufs or something else), then the superblock is corrupt hints on that.
