** Description changed: Impact ====== The current stable release (bionic) does not support booting on the Raspberry Pi 4. Several packages need back-porting from devel to support this, along with a new kernel. + + Relevant branch: + + https://code.launchpad.net/~waveform/ubuntu/+source/flash-kernel/+git + /flash-kernel/+ref/bionic-pi-4 Test Case ========= * Attempt to boot the latest bionic image (18.04.3) on a pi4; note failure * Move the SD card to a pi3 and boot successfully * Ensure all packages are up to date (apt update/upgrade) * sudo add-apt-repository ppa:waveform/pi4 * sudo apt upgrade * sudo reboot * Ensure boot proceeds successfully on the pi3 * Verify facilities (USB peripherals, USB mass storage, wifi, bluetooth, audio, etc.) work * sudo apt install linux-image-raspi2-hwe-18.04-edge * sudo reboot * Ensure boot proceeds successfully on the pi3 * Verify facilities (USB peripherals, USB mass storage, wifi, bluetooth, audio, etc.) work * Move the SD card back to the pi4 * Ensure boot proceeds successfully on the pi4 * Verify facilities (USB peripherals, USB mass storage, wifi, bluetooth, audio, etc.) work * Repeat for both archs (armhf and arm64) Regression Potential ==================== Plenty; pi4 support on bionic requires back-ports of flash-kernel, u-boot, linux-firmware-raspi2, and the kernel. Furthermore, the firmware package needs to support two kernels (the current 4.x series and the proposed 5.x series). Verification of boot, and other facilities (USB peripherals, mass storage, free memory, wifi, etc. etc.) should be performed on both archs and all supported models of pi (2, 3, 3A+, 3B+, 4B all memory variants).
