hello:
I find about VGPIO Functions have Function C use set XVS[0-2] / XHS[0-2] in Orin-TRM_DP10508002_v1.2p.pdf , as blow:
May I ask if there are any related blogs or documentation to configure the PWM signal of XHS used to sensor? I couldn’t find the relevant kernel configuration API interface and device tree file, thanks.
Hi asfsdgag,
Are you using the devkit or custom board for AGX Orin?
What’s the Jetpack version in use?
Could you help to elaborate on your use case and the requirement?
Are you working on something needing for video synchronization?
Or you just want to generate PWM for other use case?
helo:
I use custom board for orin NX，SDK version is R36.4.4， use to PWM use to sensor xhs , in Global Shutter (Sequential Trigger Mode) Operation, need for video synchronization，the problem may be related to this: Custom hard ROI mmap API flow issue - #15 by asfsdgag
Please check if there’s useful information from Sensor Software Driver Programming — NVIDIA Jetson Linux Developer Guide for your use case.
hello：
I am not find about useful information about PWM and XHS, XVS, thanks.
hello asfsdgag,
it seems VGPx aren’t available for Orin (t234) series.
please see-also pinctrl data for the NVIDIA Tegra234 pinmux, there’s no such pin configurations.
for instance, $public_sources/kernel_src/kernel/nvidia/drivers/pinctrl/tegra/pinctrl-tegra234.c
anyways..
you may use external trigger for sending pulse from hardware level to dual cameras.
