Hello everyone,

I am trying to use the NXP 88w8801 module, but I’m encountering some difficulties.

I found some information that this chip has issues with clock gating, and I would like to try disabling it.

“nvidia,disable-rtmp” doesnt seem to be working on rel35.4.1 and rel36.3(it is not present here)

I read that post below but “nvidia,disable-rtmp” doesnt seem to be working on rel35.4.1 and rel36.3(it is not present here)

Hi,
If the device cannot be flashed/booted, please refer to the page to get uart log from the device:
Jetson/General debug - eLinux.org
And get logs of host PC and Jetson device for reference. If you are using custom board, you can compare uart log of developer kit and custom board to get more information.
Also please check FAQs:
Jetson AGX Orin FAQ
If possible, we would suggest follow quick start in developer guide to re-flash the system:
Quick Start — NVIDIA Jetson Linux Developer Guide 1 documentation
And see if the issue still persists on a clean-flashed system.
Thanks!

Not sure why, but it seems that removing the ‘no-sd’ property & changing bus-width from 4 to 1 from the device tree fixes the issue. I’ll look into this more closely and will update here on how it goes.

EDIT
I think upgrade from rel36.3 to rel36.4 fixed the issue, not sure what are differences
