** 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]). An entry will need - to be added to the flash-kernel database to permit it to recognize the - platform. + (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 + * 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
