** 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. 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. Verification of boot, and - other facilities (USB peripherals, mass storage, free memory, etc. etc.) - should be performed on both archs and all supported models of pi (2, 3, - 3A+, 3B+, 4B all memory variants). + 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).
