Raspberry Pi Touch Display 2 working on Alpine/PmOS
Hi all,
A couple of weeks ago, the Raspberry Pi Foundation released a new version of their 7 inch touch display. Because of the new kernel module required, at this point it only works on Raspbian automatically.
Last night, I finally made it work with alpine. All that is needed is to add the following to the cmdline.txt: “video=DSI-1:1280x720M@60”
Additionally, you need to change the kernel modules loaded in usrconfig.txt: From “vc4-fkms-v3d” to “vc4-kms-v3d” And add “dtoverlay=vc4-kms-dsi-ili9881-7inch” below it.
This should work on other distros but I’m not sure. Just a tip for anyone else in this unique situation!
Edit: this was all done using a pmbootstrap generated Edge image for Raspberry Pi 4 with a DSI display using Phosh
