Ubuntu Linux Will Support All Raspberry PI Devices

Canonical recently announces its support plan for the Raspberry Pi 4 and said it will support all Raspberry Pi devices.

With the release of Ubuntu Server version 19.10, Canonical announced the official support for the Raspberry Pi 4, the Raspberry Pi 4 is powerful, but at a lower cost, can integrate computing workloads at the edge.

In the blog, Canonical said it will work hard to provide full official support for all the motherboards in the Raspberry Pi series. Canonical will provide Ubuntu Server and Ubuntu Core support for the existing and upcoming Raspberry Pi.

The Raspberry Pi 4 B has several different RAM options: 1GB, 2GB and 4GB. However, Canonical officially only supports 1GB and 2GB versions. Due to kernel errors, the official arm64 image of the 4GB RAM version does not support USB out of the box. Canonical engineers have identified kernel fixes and are currently testing them extensively. Canonical said that after the test is successfully completed, the update will be pushed in a few weeks.

However, developers can use a temporary workaround to enable USB on a 4GB RAM version. Just edit the file /boot/firmware/usercfg.txt to limit the RAM to 3GB as follows:

Total_mem = 3072
