CPU Bootloader is not running on device

varun_pandithurai · August 23, 2021, 3:56am

Hi @WayneWWW ,
I am using Jetson Xavier AGX

WayneWWW · August 23, 2021, 3:57am

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

varun_pandithurai · August 23, 2021, 3:58am

Hi @WayneWWW
32gb Devkit

WayneWWW · August 23, 2021, 4:00am

Please move to rel-32.6.1 and try again.

varun_pandithurai · August 24, 2021, 12:33pm

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.

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.

varun_pandithurai · August 24, 2021, 1:07pm

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

WayneWWW · August 24, 2021, 3:16pm

Did you ever successfully flash this xavier before? Or this is the first time?
Do you have other xavier devices on your side?

varun_pandithurai · August 25, 2021, 3:55am

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.

WayneWWW · August 25, 2021, 5:36am

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?

varun_pandithurai · August 25, 2021, 6:38am

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 ?

WayneWWW · August 25, 2021, 6:57am

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.

varun_pandithurai · August 25, 2021, 6:58am

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

WayneWWW · August 25, 2021, 7:01am

Please use below command and dump the result first.

sudo i2cdump -y 0 0x50

varun_pandithurai · August 25, 2021, 7:06am

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

please modified the last field 0x51 to 0x2a to match your error log.

ERROR: calculated CRC8 0x2a != stored CRC8 0x51

varun_pandithurai · August 25, 2021, 8:59am

Hi @WayneWWW
Before I was not able to flash through any means Now I am able to flash through SDK Manager
Thank you,
But I need to flash using the script here in this git GitHub - jtagxhub/jetpack-agx-build: build assistant scripts for Nvidia Jetson platforms: AGX Xavier, TX2, TX1 and Nano
But i am getting this Error

Sorry that is not our official tool. So I cannot help.

WayneWWW · August 31, 2021, 3:32am

Just add another note for this topic.

There is a “SKIP_EEPROM_CHECK” inside flash.sh to bypass the check in eeprom during flash.
But the Linux_for_Tegra directory needs to have cvm.bin that was once created in your previous successful flash case.

One can enable it by adding it to the board config (e.g. SKIP_EEPROM_CHECK=“-n”; to the p2972-0000.conf.common.)
