While install essential packages,edit file /etc/apt/sources.list and add the following:
deb http://apt.radxa.com/buster-testing/ buster main.
And get the pub key:
wget -O - apt.radxa.com/buster-testing/public.key | sudo apt-key add -.
And then:sudo apt-get update
finally,sudo apt-get install -y rockchip-overlay && sudo apt-get install -y rockpi4-dtbo.
However,E: Unable to locate package rockpi4-dtbo.

Hi,
I am having the exact same issue on the Rock4-SE, except with the bullseye-testing instead.
I am following this tutorial : https://wiki.radxa.com/Rockpi4/dev/libmraa and want to use the pwm pins to control a fan.

Could someone please help?

Hi,
I have the exact same problem. I would like to use the I2C interface of my ROCK4 SE running Debian Bullseye (Kernel: 5.10.110-11-rockchip). I also followed the instructions from the wiki page that Cos mentioned in his reply. I also found a tutorial on YouTube which does not run into the described problem: https://www.youtube.com/watch?v=3tuZ_eC_1nQ
Could someone from radxa or anyone who knows please help?
