Latest Pi4 and Buster Not Booting
|
All,
Bought two new Pi 4 boards in early
December.? They will not boot my PiGate image which is built on Raspbian
Buster, but an OS build from 2019.? Doesn't matter what size SD card,
just won't boot.? The GREEN LED flashes 4 times slowly and then 4 times
fast, then repeats.? This means there is something in the boot loader
that is failing.? This happens with both the new boards.? I bought a new
Pi 4 board in late November and it boots OK.? The same image works with
all older Raspberry Pi boards, including the Pi Zero.
Downloaded
and made an SD card with the latest Raspbian Buster from Dec 2020 and
it boots OK.? So there is something different on the newer Pi 4 boards,
unless I just happened to get two boards from Adafruit that are
defective in the same way.
This is not a power supply issue.
Just curious if anyone else has seen this
