Title:
rpi don't boot with 5.4.0-1004-raspi2
Status in linux-raspi2 package in Ubuntu:
Fix Released
Status in linux-raspi2 source package in Focal:
Fix Released
Bug description:
-> tested on raspberry 3b+ and 4b
After a fresh install of Ubuntu 20.04
(focal-preinstalled-server-arm64+raspi3.img), the rpi boots normally.
Then execute an apt update/upgrade
The Raspberry doesn't boot (no output on the console)
Reverting the device tree to the previous version resolve the issue (a
.bak is kept during the upgrade) (file bcm2710-rpi-3-b-plus.dtb for
Raspberry 3b+, bcm2711-rpi-4-b.dtb for Rpi 4b)
