Jetson TX2 flash issue, CPU Bootloader is not running on device

Hello, I am trying to flash JetPack 4.6 on my Jetson TX2 P3310 with a host Ubuntu 20.04. I have flashed JetPack 4.3 before but cannot flash JetPack 4.6.

I have tried running sdkmanager and also with the flash.sh file in the Linux_for_Tegra directory using sudo ./flash.sh jetson-tx2 mmcblk0p1, both fail at the message “CPU Bootloader is not running on device”.

I have also tried the command sudo ./flash.sh -r jetson-tx2 mmcblk0p1 to use the build image created in the first attempt. This helped me with JetPack 4.3 but does not work on JetPack 4.6.

The complete output looks like:

Do you have any suggestions?

Hi,

Are you using a DevKit or a custom carrier board?
Does the latest 32.7.4 make any difference?
Please also dump the log during flashing:

Hi @DaveYYY,

I am using a DevKit.
I try with the 32.7.4 version and the issue is the same.
Currently I don’t have a TTL to USB cable to dump the log, as soon as I can get one I will add the log.

At the moment is there any suggestions?

NO, check the log.
Or see if re-plugginig the USB cable helps.

Hi DaveYYY,

Sorry for the delay. I have try to obtain the console log, I follow the steps you provided but I am not receiving any output.

Please check if it is “always cannot see any log” case or not first.

For example, try other Jetson TX2. Try to boot up TX2 instead of flashing it.
If none of such case has the log output, it means your usb-ttl cable or setup has problem.

Hi WayneWWW,

Yes I boot up the Jetson TX2 and I have a log so the usb-ttl and setup should be good. Is only when I try to flash that there is no log.

Do you have other host PC to test? Actually ubuntu 20.04 to flash Jetson TX2 was never validated.

And could you also flash jp4.3 and see if you can see UART log on it? As you said you can flash it with jp4.3?

Hi WayneWWW,

I tested flashing JP4.6 in another PC with Ubuntu 20.04 and it was successful.

I flash JP4.3 and obtain a log.
flash-JP4.3.log (29.3 KB)

The log in JP4.3 appeared long after the line “Boot Rom communication” in the flash output. Which comparing with the JP4.6 flashing, it get stuck in that line which makes sense that I don’t have a log using JP4.6.

I appreciate if you have any idea or comment of why it is not working on my PC.

Thanks,
Kimberly Carvajal

Hi @kimberly.carvajal

Since you cannot dump log out from your problematic PC, I think it could be usb communication problem.
Try to disable usb auto suspend on your problematic PC and try more times.

Hi WayneWWW,

I check the successful PC and the problematic PC and both have the USB auto suspend enable.
For the moment I will continue with the PC that can flash the TX2, thanks for your help.
