Hi kko-smol, Xavier time is already in sync with network on boot. To synchronize your HW precisely, can you try following steps if you are not dependent on ethernet module: Enable CONFIG_TEGRA_HTS_GTE=y Modify kernel dtb: gte@c1e0000 { status = “okay”; } Run GTE userspace sample application on target device: In this example application, we are toggling 40-pin header Pin 16 (gpio=256) and feeding signals to Pin 32(gpio=257) every 1 second. In the kernel source code: locate tegra-gte-ioct…
