You should share more detail about your board, your command and what software release you are using.

Not just gave a log and said nothing.

Hi @WayneWWW ,
I tried using the build tool in this git GitHub - jtagxhub/jetpack-agx-build: build assistant scripts for Nvidia Jetson platforms: AGX Xavier,
I also tried using sdk manager but the same error comes
I am using Jetpack 4.5

So what is your board?

Hi @WayneWWW ,
I am using Jetson Xavier AGX

32gb? 16gb? 8gb? Devkit? Custom board?

Hi @WayneWWW
32gb Devkit

Please move to rel-32.6.1 and try again.

Hi @WayneWWW
I got the same error again

17:31:08 INFO: Flash Jetson AGX Xavier - flash: — Parsing board ID (ERROR: calculated CRC8 0x2a != stored CRC8 0x51) succeeded.

17:31:08 ERROR: Flash Jetson AGX Xavier - flash: command terminated with error

What is the environment of your host machine?

And why did you say “I hit same error again”? It seems what you post now didn’t show up in previous comment.

Hi @WayneWWW
I am Using Ubuntu 18.4

The previous Error I posted was from the Build tool from Git.

But I got the same error while using Jetpack4.5 and jetpack4.6

  1. Did you ever successfully flash this xavier before? Or this is the first time?

  2. Do you have other xavier devices on your side?

Hi @WayneWWW
Yes I flashed this Xavier AGX few times before it was done without any errors.
Yeah I do have another Xavier AGX there is no problem in flashing it.

Did you ever use i2c tool to modify the on-module eeprom on this problematic xavier?

Can you share the full error log as an attachment?

Hi @WayneWWW
I used I2C tools to access camera alone did not try to modify the on-module eeprom on the problematic xavier
The I2C bus I used was i2c1 (c240000)
I have attached the log here

error.txt (5.5 KB)

Is there a way to set values in on-module eeprom to default ?

Is your board still able to boot up? I mean since the flash work is not done yet, your board may still able to boot into OS.

If so, need you to use i2c tool to modify the eeprom content.

Hi @WayneWWW
The Board is able to boot to the previously installed version

Please use below command and dump the result first.

sudo i2cdump -y 0 0x50

Hi @WayneWWW
This is the result of “sudo i2cdump -y 0 0x50”
