Etson Nano Boot Issues

File System Corruption and I2C Errors
Description:
Hi NVIDIA community,

I’m experiencing boot issues with my Jetson Nano. Last time I was trying to run a ML model and it was a heavy task my jetson froze in the process and I had to do the hard reboot. and now when I rebooted it got stuck in the boot loop and During startup, several errors are appearing related to file system corruption and I2C communication. Here’s a summary of the key problems:

  1. File System Corruption (FAT-FS Error):
    I’m seeing the following message during boot:

    FAT-fs (loop0): Volume was not properly unmounted. Some data may be corrupt. Please run fsck.

    It seems like the file system on the SD card is corrupt, and I plan to run fsck to try and resolve it.

  2. I2C No Acknowledge Error:
    The boot log also shows a failure to communicate with a device at address 0x50:

    tegra-i2c 7000c400.i2c: no acknowledge from address 0x50

Error Messages (Excerpt):

4.892659] FAT-fs (loop0): Volume was not properly unmounted. Some data may be corrupt. Please run fsck.
9.905984] tegra-i2c 7000c400.i2c: no acknowledge from address 0x50

Request:
I’d appreciate any advice on:

  • How to resolve the fsck file system corruption. I tried running fsck on other ubuntu system but it read all the bits as error bits and it’s didn’t repair anything
  • Addressing the I2C acknowledgment error at address 0x50.

Thanks for your help!

Hi prashant.kumar.ug21,

Are you using the devkit or custom board for Jetson Nano?
What’s the Jetpack version in use?

Have you tried to use another SD card and reflash the board to check if it could help?

I’m using Jetson nano devkit with Jetpack 4.6.1, I tried different SD card and it’s working fine.
With the old SD card it is having boot issue with with corrupt bit’s, I tried reading it from different linux system and I’m able to access those files,
Is there any way I can recover that system?

If something corrupt in your SD card and it can not boot from it, you should reflash it to check if it could help.
I would suggest you back up those files manually if you are able to access them from another linux system. And put SD card back to reflash.
