Does jp6.2 Orin NX support NVPPS?

jp6.2 orin nx 是否支持nvpps功能

2

No, that’s not supported.

是因为硬件不支持吗

有没有通过修改硬件 支持此功能

hello 252830387,

it’s only supported on Jetson AGX Orin.
please refer to below..

$ sudo dmesg | grep "Machine model"
[    0.000000] Machine model: NVIDIA Jetson AGX Orin Developer Kit

$ sudo dmesg | grep nvpps

需要在orin nx使用此功能 摄像头和雷达，保持和系统整秒一致。 如果我们集成了PHY芯片 是否能支持此功能

hello 252830387,

you may add the nvpps into device tree to enable it, and using the GPIO mode on Orin NX for testing.
please refer to kernel documentation for more details..
for instance, $public_sources/r36.4.3/source/kernel_src/nvidia-oot/Documentation/devicetree/bindings/nvpps/nvpps.txt
