Hi

I would like to use Raspberry TVHat on jetson nano. However, the Ubuntu (jetpack4.3) does not detect the TVhat.

I would like to seek guidance on how to install the driver on Ubuntu for jetson nano.

I searched google and found the following resources :

https://github.com/torvalds/linux/blob/master/drivers/media/spi/cxd2880-spi.c
https://github.com/torvalds/linux/tree/master/drivers/media/dvb-frontends/cxd2880

Many thanks in advance

You may need to integrate the driver and device tree to try it.

Hi ShaneCCC

Thanks for responding. Would you be able to point me to some material or tutorials to explore integrating the driver /device tree?

Have a check the l4t document.

https://docs.nvidia.com/jetson/l4t/index.html#page/Tegra%2520Linux%2520Driver%2520Package%2520Development%2520Guide%2Fkernel_custom.html%23

FYI, if you want to see what your current device tree looks like, then this is present as the files in “/proc/device-tree/” (these are not real files, but are instead in RAM as a result of the kernel’s drivers). The device tree compiler, “dtc”, can be installed on the Nano (“sudo apt-get install device-tree-compiler”), and used to create a source device tree file:

dtc -I fs -O dts -o extracted_tree.dts /proc/device-tree

(it helps to browse around to see how the current tree is set up)

Thanks for the info. Will explore and revert soon.

A bit late but did you ever get this to work ?
Thanks
