** Description changed: Impact ====== A new variant of the Raspberry Pi 4 (revision 1.2) has been released (presumably to deal with the USB-C power issue [1]). Without a corresponding entry in the flash-kernel database, users of this board will receive an error whenever flash-kernel is run (e.g. on kernel updates); see LP: #1848790 comment #44 for an example. [1] https://www.scorpia.co.uk/2019/06/28/pi4-not-working-with-some- chargers-or-why-you-need-two-cc-resistors/ - Test Case ========= * On a Pi 4 Rev 1.2 board, boot an Eoan image (working around LP: #1848790 as necessary) * Attempt to run "sudo flash-kernel" * Observe the "Unsupported platform" message - * Run "sudo add-apt-repository ppa:waveform/flash-kernel" to add the PPA containing the test package + * Enable proposed * Run "sudo apt upgrade" to upgrade the flash-kernel installation * Run "sudo flash-kernel" once more, observe no error - Regression Potential ==================== Extremely low; the change is a one liner adding a matching "Machine" line to the database. It doesn't remove or alter existing lines. The worst case scenario is that the Machine line doesn't match the model in the device-tree (in which case it'll still produce "Unsupported platform"). - Other Info ========== The following branch contains the relevant changes: https://code.launchpad.net/~waveform/ubuntu/+source/flash-kernel/+git /flash-kernel/+ref/ubuntu/eoan-devel
