Re: Latest Pi4 and Buster Not Booting

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.

This is not a power supply issue.

Hey 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1yr) is obsolete. 

https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=58151#p1485558 --> 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:

What’s being put to terminal when it boots? With out that, know what is failing is going to be tough to troubleshoot.

Mark,

Are the two failing to boot boards a different revision number than the ones that book OK?

Not sure if the below URL is significant, or not. Might be worth a look, just in case.

Hi John,
You might try KM4ACK's Build-A-Pi. It will build and install QSSTV for you.  I have used build-a-pi to install Ham Software on both RPi3 and RPi4 systems. You can install one app or several.  https://github.com/km4ack/pi-build

Re: losing blue tooth on raspberry PI 4

USB devices being given a different /dev ID at boot is quite common. I'm not aware of it happening when software restarts and I can't say if it can or can't happen. Regardless I'd take a look at creating a udev script to marry a given /dev/ttyXXX#  (/dev/ttyUSB0 for you) to a particular USB device, effectively reserving that /dev ID. I'm not the person to give specific instructions but starting here might help ... https://opensource.com/article/18/11/udev

Re: losing blue tooth on raspberry PI 4

Hey Jay,

When you say "usb0", I assume you mean "/dev/ttyUSB0".  Right?   Few other questions for you to ponder:

   - What radio are you using?
   - Is the username you're logging into the Raspberry Pi in the "dialout" UNIX group to allow full access to most serial ports?
   - Are you also sure this is the right serial port?  LInux can move serial ports around unless you're using UDEV or the /dev/serial/by-id/ device name for persistent names

in the settings when you set the port to port 0, is there an option to save preferences?

David,

In skcclogger, their are radio setup options for usb. For some reason, the software switched to (or I fell on keys) a different tty setting instead of the usb0 one. When I switched it back to usb0 the problem with bluetooth went away on both the mouse and the keyboard.

You should be able to get the software here: http://www.ac2c.net/Downloads.php

Re: losing blue tooth on raspberry PI 4

Hello Jay,

I got this error when the program started and then I lost bluetooth:
raspberrypi kernel: v3d fec00000.v3d: MMU error from client L2T (0) at 0x3781000, pte invalid

Hmmm.. that error seems to be "xv" video related and NOT necessarily bluetooth related.  Maybe there were other bluetooth errors listed that you missed?  Could also be that you might need to turn on additional debugging in the bluetooth stack to get things logging. 

When this issue hits, do you only loose bluetooth keyboard and mouse functionality or does the video go out too?  If you're using Wifi on your Raspberry Pi, does it continue to work?  Googling this error brought up a few threads like:

   No solution given but reported by other users
      - https://www.raspberrypi.org/forums/viewtopic.php?t=277917

   This thread talks about on the Rpi4 using one HDMI port $#1 vs #2 might matter
      - https://forums.gentoo.org/viewtopic-t-1107050-start-0.html



After changing the software's usb port the mouse and keyboard stopped locking,

I don't understand what you mean here.  What software are you talking about here?  skcclogger?  What did you change in it USB wise?  I did look a little at this skcclogger program but the Linux version is not posted on the website and instead, it seems people have to request a copy of it.  Does it natively run on Linux or are you using something like Wine or some other emulator to run it?  If I was to guess, this program is using the legacy "xv" video method in Xwindows for Linux and it's having some sort of issue.
