[jetson-flash] 'No magic number found' when flashing to devkit.

[AlexandreLeboucher]

Hi all,

Followed the steps here without VM on Ubuntu 18. This worked perfectly for the past month but stopped working today. Tested on 2 different devkits and two different machines. Seems like a jetson-flash issue ?

Jetson Nano 2gb not showing up on Dashboard

Sorry for the delay @AlexandreLeboucher, but I sorted this out. Here are the steps I took to get my Jetson online with balenaCloud: VM Setup: Create VM, using Ubuntu 18.04 image. sudo apt-get install libxml2-utils git build-essential curl dirmngr apt-transport-https lsb-release ca-certificates curl -sL https://deb.nodesource.com/setup_12.x | sudo -E bash - sudo apt-get install nodejs git clone https://github.com/balena-os/jetson-flash.git cd jetson-flash npm install Launch Firefox,…

Any idea what may be causing it ?

Here’s the trace :

Hi @AlexandreLeboucher, looks like the Nvidia servers that provide the BSP archive with the Tegra host flashing tools had some problems and were returning a 404 code. If you have the BSP archive saved somewhere you can use a local webserver and flash your devices as described here.

Hi @acostach,

Thank you very much for this information. It started to work again for us.

Appreciate the support,

Alexandre
