Rock-5T-DTB:

This repo provides a device tree blob for the Radxa Rock 5T. This is useful when you want to access the additional ethernet port, wifi and bluetooth and possibly other peripherals for the rock 5t when using the 5b plus image from https://joshua-riek.github.io/ubuntu-rockchip-download/ . This is not a valid solution but a handy hack if you don't like or want to compile the linux kernel, u-boot and rootfs yourself.

Note: Tested only on ubuntu-24.04 ( noble ) . It most probably works on jammy as well, but hasn't been tested on it yet.

Prerequisites:

1. Rock 5T
2. Ubuntu for the Rock 5B Plus installed on the Rock 5T from this link: https://joshua-riek.github.io/ubuntu-rockchip-download/

Instructions:

1. Clone the repo:

   git clone https://github.com/rafayahmed317/Rock-5T-DTB.git
   cd Rock-5T-DTB/
   

2. Make the script executable:

   chmod +x configure.sh
   

3. Execute the script with root privileges:

   sudo ./configure.sh
   

Note:

The script is going to modify the first mention of fdtdir in your /boot/extlinux/extlinux.conf to another value. Ensure that the first label in extlinux.conf is the one you boot from. After the script runs the output should be like the following:

## /boot/extlinux/extlinux.conf

If the output is not like the above and the script modified some other label, run the following to restore extlinux.conf:

sudo mv /boot/extlinux/extlinux.conf.bak /boot/extlinux/extlinux.conf

If things still mess up somehow, you will have to reflash the default image, or maybe interact with u-boot during boot to load the correct fdts.
