Hi,

I’m trying to flash a Jetson TX2 using the jetson-flash tool and I’m getting the following error using the command /bin/cmd.js -f image_tx2-2.73.1+rev4-v12.4.6.img -m jetson-tx2

If jetson-flash doesn’t work, what is the recommended way to flash a tx2? I have confirmed everything works for the nano, same code isn’t working for the tx2.

Thanks,

Andrew

Now that I look at it, the instructions given in the BalenaOS downloads page (when you click add device) talk about using an SD card. The TX2 I’m using is the emmc version that is flashed over USB. Are any of the available TX2 boards meant to be flashed over USB to the EMMC?

Hi @smithandrewc , what version of the jetson-flash tool shows this error for you? Is it v0.5.9 or some other version, and which nodejs version do you use?

Also, what is the exact commands that you used to:

  • install or set-up jetson-flash
  • flash the board

The log you pasted seems very similar to Can't seem to flash images built from 2.73.1 · Issue #43 · balena-os/jetson-flash · GitHub which got fixed in v0.5.8, but let’s first see what versions you use.

Thanks @acostach . I don’t think the problem was the flasher, I was using an older version (v0.5.7) but I think it had more to do with the image I was trying to flash (not being meant to flash over USB). I compiled my own balenaOS image from source and used the non-flasher image and it flashed properly. It’s not booting but I think that requires a new thread.

Thanks.

Hi Andrew, images newer than v2.72.0 need v0.5.8 at least, for the reason mentioned above. The TX2 image from the dashboard is a flasher image, so jetson-flash extracts the OS image from it. You should pass the flasher one to jetson-flash, even if you’re doing a local build.
