Hi All,
RidgeRun is working on a free version of the driver. We expect to have it done in 2 to 3 weeks. As you noticed we already have the IMX477 driver for other cameras so we are porting the driver to make it working on Xavier NX + Raspberry Pi HQ. This driver should also work on Jetson Nano. Please stay tuned, we will add the release notes in this wiki page soon:
