RPi 4B with 1 or 8 GiB RAM does not boot #1314
Description
Current Behavior
For certain new models of Raspberry Pi 4B, in particular 1 GiB and 8 GiB, we've seen problems where the BootROM doesn't even load u-boot.bin (the "kernel"):

This is a backport of the latest rpi-firmware on Buildroot master. Signed-off-by: Joachim Wibergtroglobit commentedon Dec 15, 2025
Yes, we added the issue after the fact and I've just not gotten around to updating the ChangeLog.
