Hi, I was checking the TRM from the Jetson Thor, and it seems to have an AON, like the Orin family, but I could not find in the Jetson Linux BSP any way to program it, like the same feature in Orin. Do you have any news or information about when this feature will be enabled on the device?
Best regards,
Ivan Rodriguez

Hi,
The content is missing in Jetpack 7.0GA. We will check to add it to next release.

5

Any public timeline for when will be available? (like in the 7.2 update or further in the pipeline)

6

The next JP7.1 release is scheduled at 2026/Jan.

Hi,
Do you want to control the AON GPIO pin when the system suspends? On Jetpack 7.0GA, you can configure AON GPIO pin through pinmux spreadsheet. And use libgpiod to set high/low of the pin. The non-supported case is to set high/low when the system suspends.
