Heads up: New Raspberry Pi OS Bookworm 12.2 OS upgrade breaks Direwolf v1.7 GPIO pin access
开云体育Hello Everyone,Just as a heads up but Raspberry Pi OS Bookworm received a major update earlier this week which includes the Linux 6.6.20 kernel and many other changes: ?? In this new OS update, the classic way of interfacing with GPIO pins has now been DEPRECATED and this breaks Direwolf v1.7 if you use GPIO pins to assert the PTT line to your radio, light up an LED with the DCD signal, etc.? The solution was already committed to the Direwolf DEV branch back in November 2023 which will eventually become Direwolf v1.8.? You can read up about that and how to both recompile DIrewolf and reconfigure your direwolf.conf file to use this new gpiod interface here: ?? I'm happy to report things are working for me with this new code but I felt compelled to report this as this very disruptive change coming in the middle of the Bookworm OS lifecycle is going to create some pain for some people.? I'm also updating my Raspberry Pi docs and automated build script later to day to reflect this change. --David KI6ZHD |

Yah, this is an epic disaster for five reasons,
1) breaks every gpio document on the internet 2) breaks direwolf 3) gpiozero (the lauded replacement) burns half a cpu just to monitor a button, nobody there cares 4) gpiod requires 30 lines of python to monitor a button 5) You need different code depending on which Pi model you're using it's a huge disservice to the educational/pi community. imho, -craig KM6LYW |

No different than the
ethernet / wifi naming issue removal / changing of the camera functionality any other number of changes made by the program developers @ RPiFoundation, who have by actions have shown they have changed their focus to the commercial side instead of what gave them the capabilities to create in the first place. I gave up on them a few reversions back. In order to 'beat the system' I began using the tool that they use to build my own images with the reversals enabled to maintain the software I used, but I've given that up because they made no way to reverse the most recent changes. I'm on debian 11 and debian 12 for almost everything, using m73TFF and Lenovo ideapad 3s running xcp-ng and docker to multi-task my tools...? -- = = = = ? Kevin? --? KD9EFV |
开云体育Are you asking if you can switch to gpiod on an older non-Bookworm version OS?? If so, there might be other dependencies you will also have to install but I can confirm that gpiod is in Bullseye, Buster, and even Stretch has gpiod.? To be clear, you will also need to switch to using the Direwolf "Dev" branch which has the new Direwolf v1.8 code, recompile Direwolf, and use that new version. --David KI6ZHD On 03/17/2024 10:06 AM, dtmenges@...

As I noted in an earlier response, I ran into this yesterday right after an update. I would rather bite the bullet now rather than in the future. For Direwolf, is this a simple matter of installing gpiod and libgpiod-dev and then changing the direwolf.conf file? |
开云体育Just the opposite. I was asking if all I need to do is add?gpiod?and?libgpiod-dev to the updated Bookworm and change my direwolf.conf file.? I'm already running DW 1.8A. You will still need to re-compile Direwolf 1.8A once the libgpiod-dev package is installed so it can been seen and linked in.?

I ran this?sudo apt install gpiod and everything went fine.
I then ran?sudo apt install libgpiod-dev and the following is the result. Reading package lists... Done

This worked for me with RPi 5 bookworm:
sudo apt install gpiod libgpiod-dev Did you type the command or copy/paste it from somewhere? Some document editors will change the ASCII "-" (minus, dash, hyphen) to some other non-ASCII character which looks the same on the screen. The Radio Interface Guide, in ?? ,? has been updated with more details about using gpiod. 73, John WB2OSZ |

John,
Just saw the updated Radio Interface Guide. I'm going through those links to gain some background. The second link has two procedures. Should I run those? I have copied commands and then pasted them into a text document. After lunch I'll try replacing the - characters just to make sure. Usually I copy and then paste into a local text file just to make sure any goofy formatting codes are scrubbed. Dave |

The good news is that when I set up a clean SD card with 32-bit Bookworm and followed the instructions in the new Radio Interface Guide and everything is peachy. Somehow, there is no libgpiod-dev package on my other Pi and I'm not sharp enough to figure out how to get it there.?I checked both with dpkg -s libgpiod-dev.
Thanks for the help. I'll contemplate this a bit more before raising the white flag. Dave |

Did you try to install it using apt?

do sudo apt update sudo apt install libgpiod-dev It's available in the repository for both Buster (Debian 10) and Bullseye (Debian 11) on two old model B Pis I have in service, both running whatever image the Pi Foundation supplied at the time. sudo apt list libgpiod-dev will show if it's available.
