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

Product support

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 ?

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
