Jetson AGX Orin Output the clock to the GPIO pin

[Andyyyyy]

Hi,

I now have a problem, I want to set the H57 pin to GPIO.
Now I have updated the pinmux and device tree and have successfully set it to GPIO.

But I would like to have GPIO output a 3MHz clock that gives me the ability to customize the device on the carrier.
I checked “Figure 2.9 TSC Controlled Signals” in “NVIDIA Orin Series System-on-Chip”, page 4558. I should be able to output signals to the pin. Maybe my understanding is wrong, maybe my description is not correct.

Can you tell me how to accomplish my requirements…

Hi Andyyyyy,

Are you using the devkit or custom board for AGX Orin?
What’s your Jetpack version in use?

Please refer to the following instruction for this use case.
Generic Timestamp Engine — Jetson Linux Developer Guide documentation (nvidia.com)

Hi https://forums.developer.nvidia.com/u/KevinFFF

I used a custom board, using JetPack_5.1.2.

Custom carrier board should also work with Generic Timestamp Engine, please refer to above instruction and check if it could meet your requirement.
