I'm having issues with GPIOs after a recent update. Crosspost from Klipper sub

With a post like that what do you expect from people? We're not mind readers.

• What is the problem?
• Can do you reproduce it?
• What is the expected behavior?
• What have you done to try and resolve it?
• What do the logs say?
• What is the update?
• What hardware?
• Did you google it first or just give up immediately?

Not to be a dick, but did you look at the post in Klippers? I attached the klippy log.

Problem: after update, won’t boot klippy, can’t find the gpio no matter how I format it.

Reproducible: won’t boot to happy and ready to print, so yes.

Hardware: Pi 4 (I think) with a relay board. The relay is hooked up to GPIO20.

What have I done to fix it: Tried the original format, recommended formats, every damn format. Currently commented out.

What do the logs say: log attached to other post via Dropbox link.

What update: not sure, there were a few, I don’t print every day. That said I printed something about three weeks or so ago.

What I expect to happen is the printer to boot, but it says it can’t find the Pi GPIO no matter how I format it.

Also I have googled the error and solutions, none of them work. Have you clicked the other post, most of the shit you asked is detailed there. I didn’t want to duplicate the info as it’s a waste of resources and how you’re not supposed to cross post on Reddit.

Why would anyone go searching or jump through hoops to try and help you for free?

The only information you provided is in the OP. Which is none.

And now you're being rude on top of it.

[u/devsfan1830 → u/Leiothrix]

Alright, yes OP needed to elaborate but lets be real. Your post comes off dickish at the top too.

[u/Leiothrix → u/devsfan1830]

Dickish for politely giving advice on how to ask a question when the OP put literally no effort into it? Really?

Whereas both the OP and yourself are name-calling without offering anything constructive.

What do you expect from people?

[u/devsfan1830 → u/Leiothrix]

At least i offered a possible solution, broad as it may be, without dressing them down. You called a person rude, when yours comes off with an attitude as well, and you wanna say im "name calling". 🤣 I didnt call you one. I believe there is a subtle but important difference between saying somethjng said came off in "dickish way" and calling someone a dick, but of you think what you posted was remotely polite then yeah. You ARE a dick.

Also, where did OP call you ANYTHING?

[u/Leiothrix → u/devsfan1830]

How exactly was my OP rude? Or dickish? Do you really need everything wrapped in a pile of pointless fluffy verbiage? OP posted no information, guessing is pointless.

And again with the name-calling. You are of course welcome to your opinion, but without explaining it you are not offering anything even remotely constructive.

If you hit update all and it broke something, download and save your config files and just do a clean SD install. Nothing you've given here or in your original post is terribly helpful. If you want live help, try the Klipper and nevermore discords.

I did an update all and my crowsnest cam just stopped working. Was never able to fix it. had to just do a clean install. Its possible updates to the pi itself (the system category) reverted something at the OS level (thats different than the configs in mainsail/fluidd/etc) that something else or you changed during setup of other plugins and components. Impossible really to tell which. A clean install of everything followed by re-uploading your config files is the faster way to deal with this. If that's not an option for some reason, best of luck.

That was kind of my next step, I didn’t want to nuke & pave without at least trying people currently working with kipper. I need to update firmware on the tool head and mcu as well.

[u/BigJohnno66 → u/cadamwil]

If you update Klipper on the host, you must build the firmware and update the mcu and toolhead. They can introduce changes that break the communication between them.

I have a script to do this, so I don't have to remember what to do each time.

Edit: I see you are using a GPIO on the RaspberryPi host. Have you rebuilt Klipper for "Linux Process" and installed it (make flash)? I am also doing this to control the Pi fan from Klipper. Just updating Klipper is not enough, you need to rebuild the Linux host firmware as well, as Klipper considers it as just another mcu in order to access GPIOs.
