How to install firmware for TX2 on the J120 Auvidea

Hi all,
I have been trying to install the new auvidea firmware version 2.2 on my J120 board with TX2.
The previous firmware, 2.1 had a readme txt file, which mentioned how to install everything.
The current firmware version has nothing like that! Even the folder is called “J90”, even though it is for various boards.
Completely clueless on how to install this?!
Any help would be appriciated.
PS: All I wanted is to ensure my USB 3.0, USB 2.0, Fan, Ethernet, and the M.2 to work.

Hi birthegreat,

You may need to contact with Auvidea if can have provide the readme file for firmware version 2.2, or you may try the same step as firmware version 2.1 to see if can work.
