Latest Pi4 and Buster Not Booting
|
Mark Griffith
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 Mark KD0QYN

The older buster doesn't have the proper firmware for the Pi4 boards, and newer Pi4's are coming with the firmware on them (unless they are the 8G versions)? you can take your older one and put it in the Pi 3, and do the apt update, apt full-upgrade and rpi-update, shut it down and pop it into the Pi4 and it will boot.? Once it's loaded on the Pi4, do the update/upgrade again, then do a sudo rpi-eeprom-update -a -d and reboot again On Fri, Jan 1, 2021 at 12:15 PM Mark Griffith <mdgriffith2013@...> wrote:

¿ªÔÆÌåÓýHey Mark, Is your Raspberry Pi OS fully up to date on your SD card?? I imagine the bootloader from your 2019 based Buster image (now >1yr) is obsolete.? --> scroll down to the table in this post and scroll down WITHIN this table: ?? Long flashes??? Short flashes??? Status ?? 4??? ????????? 4??? ????????? Unsupported board type On a working Rpi4 board, do a full OS update and then reboot to confirm things still work.? After that, do a shutdown, move the updated SD card to your problematic Rpi4 board and see if that helped. There is also the possibility of a corrupted EEPROM (only present on Rpi4 and newerboards).? You can try re-flashing that on your new boards: ?? --David KI6ZHD On 01/01/2021 12:08 PM, Mark Griffith

Well, as I mentioned in my message, the same image worked on all Raspberry Pi boards from the Pi Zero up to and including the Pi4 (2GB) until last month (Dec) when two new boards will no longer boot, so the problem is not in the image.? The older Buster *does* work with the older Pi4.? It was the OS releases prior to Buster that did not work with the Pi4 or 3B+.? The new problem *seems* to be something has changed on the newest Pi 4 boards so it won't boot unless you use the latest release.? This is pretty typical of the Raspbian releases, they are scheduled to coincide with hardware changes.? I'll just bet it has something to do with the new Pi400. When I create my PiGate images, it takes a while to build it as so many software pieces have to fit together for it to work as seamlessly as it does.? Doing an apt update or upgrade many times makes the it quit working because of the nature of open sourced software.? Too often, people make small changes to the software, like renaming programs, or changing the location or structure of config files or requiring different or new libraries.? This is particularly true of the AX.25 kernel stack.? That's the nature of the beast, like it or not. Many people download my software images to build their own PiGate systems.? Now, I have an image that won't work with the newer Pi4 boards they will most likely buy soon, so I have to fix the problem and issue an update.? I really don't want to go back to having to support more than one image, but I will shortly start getting message that the image they downloaded won't work, so I need an easy answer. To a smaller degree, this effects the PiGate systems that I assemble for other hams, which is how I discovered this problem.? In both cases, I can't issue a set of instructions for each PiGate user to run to update their boards or apply new firmware, I have to make it work with what they get from the board vendors.? That way the image boots and works without any muss or fuss or engaging in support from me. However, thanks for your comments. Mark KD0QYN

David, There is nothing on the terminal.? The LED blinks are the clue of what is going on, it can't start the boot loader.? The newer Pi4 boards probably have a new boot loader name hard coded into the firmware.? This is not the first time they have done this. Thanks for your input. Mark KD0QYN

David, Thanks for the comments.? As I mentioned, the OS boot loader is fine for Pi4 boards I bought prior to Dec 1.? Now it is not, so yes, the version of Raspbian is probably too old for these new boards.? That is my point.? I'm just asking if anyone else has seen this behavior, or perhaps, very unlikely, I have two Pi4 boards that are acting weird. Mark KD0QYN
