dfu-util; No DFU capable USB device available

[Janik-Haag]

When trying to use pineflash 0.5.1 and dfu-util 0.11 the throw this error:

dfu-util; No DFU capable USB device available

Maybe related to #45

[Janik-Haag]

Are there some udev rules I have to add for that to work?

[Spagett1]

There shouldn't be any udev rules, could you please try flashing your pinecil manually with dfu-util from the cli and send the command here? https://ralim.github.io/IronOS/Flashing/Pinecil%20V1/#linux-and-mac

[Janik-Haag]

I'll try tomorrow since it's already quite late for me local time. Btw could you link me the code snippet where dfu-util gets called, I'm currently packaging pineflash for NixOS and will probably have to patch the expected dfu-util binary path.

[Spagett1]

Sure, this is the code snippet for the v1 on Linux

            #[cfg(target_os = "linux")]
            let command = Command::new("pkexec")
                .arg("dfu-util")
                .arg("-D")
                .arg(firmware_path)
                .output()
                .expect("Could not flash soldering iron");

this is on line 93 of the src/submodules/flash.rs file, the pinecil v2 code is a bit further down the file.

[Janik-Haag]

Ah okay you are constructing a comment and then executing it in a shell context, that's what I thought, should be an easy fix I just have to patch dfu-util to the absolute path in the nix-store since in nix $PATH works a bit differently to be able to avoid version conflicts.

[Spagett1]

Ah interesting, also you should know the Command::new() doesn't call a shell, it works off of PATH and other environment variables though, it may be easier for you to edit the command call with .env() but I'm really not sure, I've played with nixos briefly but never got into packaging for it so I'm not sure.

[Janik-Haag]

Since I couldn't sleep I did the totally normal thing of debugging this:

dfu-util -D Pinecil_EN.dfu doesn't work and throws this error:

dfu-util 0.11

I randmesg --follow to get the usb status messages and here is the log:

I of course searched for the issue and found https://sourceforge.net/p/dfu-util/tickets/127/ And tried adding the udev rule as described in some comment and rebooted but that didn't do the trick for me. I'll ask in the local hackspace if some one can lend me there pinecil so I can check if mine is just borked or if it is some issue anywhere between libusb, dfu-util or NixOS. I know that a few people there also own a v2 so I can test that as well.

on another note the copy log button in pineflash isn't working for me :/ I'll have to look at how that is implemented, probably just some incompatibilities with sway had the same issue with another project https://github.com/AgathaSorceress/url-eater/issues/2

Also I'm guessing there is only a discord server and no matrix channel, right?

I'll close this since this seems to be a issue with dfu-util and not PineFlash

[Spagett1]

Interesting, definitely seems like a dfu-util thing. It's possible someone in the pinecil matrix can help out if this is a known issue in general, I don't really use matrix much but I wouldn't be opposed to bridging it, I don't have a ton of time though to do that though.

[Spagett1]

Well it turns out making and bridging a space is pretty easy, I've made a matrix space @Janik-Haag if you wanted to ask questions in relation to nix, suggestions, or whatever now. You can find the link in the readme.

[Janik-Haag]

Thank you, I joined the space and wrote some stuff :D
