Ubuntu 16.4 32 bit on TX1?

Hi,

I trying to upgrade my TX1 to Ubuntu 16.04? need it for 32 bit.
After upgrade the USB doesn’t works.

I find only 14.04 Ubuntu image.

So is it possible to install Ubuntu 16.4 32 bit with relevant drivers on TX1?
And how?

Thank you.

32-bit hasn’t been officially supported on Jetson TX1 since L4T R24.1 was released in May 2016.

To get Ubuntu 16.04, please upgrade your Jetson to the latest JetPack (currently version 3.1).

Thank you
