Let me share how to get the J120 working with Jetpack 4.2.2.
Jetpack 4.2.2 as well as 4.2.1 contain a number of changes to the device tree compared to Jetpack 4.2.
That seems to be the reason why I could not get my TX2 working with the latest Version 2 of the Auvidea firmware when I moved from 4.2 to 4.2.2.
I am attaching my edited .dtsi files here which contain all changes needed to run the J120 along with JP 4.2.2 you may use when you compile the kernel.
Please follow the instructions here to compile the kernel manually and to flash it to your TX2:
Before step 3, you need to copy the attached .dts and .dtsi files into the respective
After flashing the kernel, you can continue to install the Jetpack libraries by using SDKManager as usual.
As far as I could test, you get one USB3.0, one USB 2.0 and one microUSB 2.0 port operational.
- no OTG support on the microUSB port - so you are not able to flash the TX2 from a host computer when mounted on the J120 (for flashing, you need to switch to the Development Board) I am not sure if that ever worked with the J120 Rev 8 though…
- Fan is always on. There is no access to the fan. This issue also persisted with the official Auvidea firmware 2.0 and JP 4.2
If anyone of the experts here has an idea to get fan control working along with the J120, I would highly appreciate it - Thanks!
