Mediatek RZ616 Wi-Fi 6E 160MH // WIFI_MT7922_patch_mcu_1_1_hdr.bin failed with error -2 PowerPC P1010RDB-PB

[4920441]

Hi,

I recently got a now obsolete Sophos RED15w with a minipci slot, and thought, since it has 128 MB Nand 512 MB Ram and Gigabit combined with an P1010E CPU it should be fun to replace the old minipci card with a Mediatek MT7922 AX Card (and an adapter off course) to make use as a AX Accesspoint with Openwrt.

But, it ain't so easy as I expected.

First I tried 23.05 for this, selected the mt7921e driver and the firmware for the mt7922, build uploaded it and got an error like

mt7921e a000:01:00.0: Direct firmware load for mediatek/WIFI_MT7922_patch_mcu_1_1_hdr.bin failed with error -2 [ 10.245053] mt7921e a000:01:00.0: Falling back to sysfs fallback for: mediatek/WIFI_MT7922_patch_mcu_1_1_hdr.bin

when the driver tries to upload the firmware.

I then found this site on the internet which pulls the latest firmware images directly, but that had no effect either

[(https://mans0n.github.io/2023/01/24/diy-6ghz-ap/#MT7922)]

After that, I checked out the master branch of openwrt, compiled and flashed it again, but there is not much of a change.

The device is correctly shown on the pci bus, as well on the linux side as on the u-boot side as well:

01:00.0 - 14c3:0616 - Network controller

Here is the full dmesg output ot the boot via serial terminal)

2023-10-18-ralinkmt7922_2.txt

Is this a problem with the CPU/platform or do I miss something totaly obvious here?

I found a couple of stories with the same wifi card combined with x86 openwrt systems and they didn't seem to have any issues at all.

Thanks for your time and your work! Really appreciated.

Cheers

After checking the makefile of mt76 (https://github.com/openwrt/openwrt/blob/main/package/kernel/mt76/Makefile), I think this is because the ipk package doesn't include the following firmware files

https://github.com/openwrt/mt76/raw/master/firmware/WIFI_RAM_CODE_MT7922_1.bin https://github.com/openwrt/mt76/raw/master/firmware/WIFI_MT7922_patch_mcu_1_1_hdr.bin

upload these two files to /lib/firmware/mediatek, problem can be solved.

Hi,

I'll try this again, but I don't see any difference with the firmware files I already manually put there, mentioned also in the link I provided:

I then found this site on the internet which pulls the latest firmware images directly, but that had no effect either

https://mans0n.github.io/2023/01/24/diy-6ghz-ap/#MT7922

wget https://github.com/openwrt/mt76/raw/master/firmware/WIFI_MT7922_patch_mcu_1_1_hdr.bin 
wget https://github.com/openwrt/mt76/raw/master /firmware/WIFI_RAM_CODE_MT7922_1.bin

Seems the same, to me....

And yes, they are in '/lib/firmware/mediatek ' - I hope that is correct as well?

If you are using OpenWrt snapshot version, you can install kmod-mt7922-firmware package to solve this issue.

Fixed by https://github.com/openwrt/openwrt/commit/9eecf4905375777e2048177dbe4d83fee5da9ee1

Erm.... no it does not for me - I tried to download the firmware files in the beginning and I even tried it with the provided links as well, but there is no change. It tries to load them but fails

It seems as it isn't able to upload the firmware file, but not because it is not there, though anything else is not working at this point:

Anyway, error -2 means No such file or directory.

i have same issue and i fixed it in a non practical way kmod-mt7922-firmware isn't available for me bc i am not using lastest commit of mt76 so i copyied the fireware from my main pc that run linux.
