Hi,
I am telling you that *initial direct loading is broken*!
Direct loading of v77 firmware, when ax201 is built in kernel is
broken! This worked in kernel 6.4.x year ago.
Proof to that is if I copy .77 to .76 and I use my patch *just to repeat
direct loading* of next file, and 60 seconds later it actually loads v77
firmware that is named .76.ucode and this works.
That also tell us that current firmware v77 is ok!
Hope that that explains what problem is.
I can debug more if needed, but I am not programmer and It would need
substantial more time to find why initial direct loading fails and how
to fix it.
Kind Regards,
Zoran

Hi,
Sorry, what, I'm confused.
it will not even try to load next working QuZ-a0-hr-b0-74.ucode
That's intentional... We released -77 firmware for this device in 2022,
a little over two years ago. We can't and won't support ancient firmware
*forever*. We've already supported it for a very long time.
either direct loading or with included firmware in kernel
("CONFIG_EXTRA_FIRMWARE="i915/tgl_dmc_ver2_12.bin intel/ibt-19-0-4.sfi intel/ibt-19-0-4.ddc iwlwifi-QuZ-a0-hr-b0-77.ucode"
caused kernel reboot) and that kernel 6.4.X could load
firmware direct or included.
I have no idea what might be the issue here. Perhaps your kernel ends up
too big for the way you're booting it? If you insist on booting without
initramfs but with iwlwifi built-in, you need to debug and fix *this*.
Or I guess you could always try probing/binding the driver again after
the system really boots.

but I guess that's when you try to have wifi built-in and no firmware
built-in
