[FW13 11th Gen] `OSError: [WinError -2147024846] The request is not supported`

[lekorrigan]

Thanks for creating this! However it doesn't run on my FW13 11th gen.
I get the following error:

This is after installing the PawnIO drivers. It didn't work before either.

Hi, I've just added a traceback to this build, if you could send that: https://github.com/Steve-Tech/YAFI/actions/runs/17661265061

I have a feeling PawnIO isn't detecting the EC properly though, which isn't gonna be easy to debug.

Thanks for creating this!

No worries!

[lekorrigan]

Hmm sorry, I'm not sure what you want me to do with this. I don't have a way to build YAFI myself I'm afraid...

[Steve-Tech]

Oh sorry, download the artifact on that link, it should be an already built version of YAFI, and send the troubleshooting info again.

[lekorrigan]

Ah OK!

The error I now get is:

Would you be able to try this build: https://github.com/Steve-Tech/YAFI/actions/runs/17694209195

But before you run it, could you download DebugView, run it as administrator, and enable Capture -> Capture Kernel and Capture -> Enable Verbose Kernel Output. Then when you run YAFI, could you screenshot any lines starting with [PawnIO] debug_print:.

[lekorrigan]

Thank you, I have tried.

Debug View:

[PawnIO]

debug_print: Cannot find EC memmap.

I'm afraid that's it...

[Steve-Tech]

Thanks a lot, that narrows it down heaps!

debug_print: Cannot find EC memmap.

The Intel models do have a different address for the memory map, the PawnIO module should already be accounting for that, but obviously there's a flaw in my code somewhere.

I'll have a proper look tomorrow, but in the meantime could you run msinfo32 and open Hardware Resources -> I/O, and send a screenshot. I'm specifically looking for something at 0x00000900, but don't stress if it doesn't show.

[lekorrigan]

Glad it helps. Here you go:

[Steve-Tech]

Actually, after having a quick look at what Framework does with framework-system, I think it might have an MEC EC, which is different enough that I'm not comfortable writing code without being able to test it.

Hopefully Framework adds support for their new Windows driver in a BIOS update soon.

I've created an issue for CrOS_EC_Python: Steve-Tech/CrOS_EC_Python#1

Hey, just to let you know : i got the same error (request not supported) on my framework 13 1240p with the 0.5 release and PawnIO, YAFI launched as admin.

Yeah, the PawnIO module isn't compatible with Intel 11th, 12th, and 13th gen Framework laptops.

You're either gonna have to wait for Framework to add support for their new Windows driver in a BIOS update soon, or for me to acquire a 11th-13th gen mainboard.
