MT7902: hardware init failed ("Timeout for driver own", ASIC revision: 30003, Manjaro 6.15)

[rolliebae]

Hello!

I'm trying to get Wi-Fi working on my laptop with a MediaTek MT7902 chip under Manjaro Linux (kernel 6.15.7-1-MANJARO).
The driver builds and the module loads, but no Wi-Fi interface appears, and I see repeated errors in dmesg:

mt7902e 0000:02:00.0: Timeout for driver own
mt7902e 0000:02:00.0: hardware init failed

System information:

• Distribution: Manjaro Linux
• Kernel version: 6.15.7-1-MANJARO
• Chip: MediaTek MT7902
  (lspci: 02:00.0 Network controller [0280]: MEDIATEK Corp. Device [14c3:7902])
• ASIC revision: 30003 (from dmesg)
• Driver: OnlineLearningTutorials/mt7902_temp (latest commit, cloned with --depth 1)
• Firmware files are present in /lib/firmware/mediatek/:
  • WIFI_MT7902_patch_mcu_1_1_hdr.bin
  • WIFI_RAM_CODE_MT7902_1.bin

What I have tried:

• The module builds and loads without errors.
• Firmware files are unpacked and permissions are set.
• Tried different firmware versions (from Windows driver and linux-firmware).
• Tried different kernel versions (6.12, 6.15).
• Secure Boot is disabled.
• The chip is visible in lspci, but no Wi-Fi interface appears.
• No "firmware not found" errors in dmesg, only "Timeout for driver own" and "hardware init failed".

dmesg output:

mt7902e 0000:02:00.0: enabling device (0000 -> 0002)
mt7902e 0000:02:00.0: disabling ASPM  L1
mt7902e 0000:02:00.0: ASIC revision: 30003
mt7902e 0000:02:00.0: Timeout for driver own
mt7902e 0000:02:00.0: hardware init failed

Questions:

• Is ASIC revision 30003 supported by this driver?
• Is there a working driver/firmware combination for MT7902 on Linux?
• Is there anything I can do to get Wi-Fi working on this chip?

Thank you for your work! I am ready to provide any additional logs or information if needed.

Currently there is no working driver of MT7902 for linux. I am trying if it works. I searched the web and find some android version of code and some old code. Trying if some trick works as mediatek not taking responsibility to avail the driver for linux. I am also facing some issue with fan control also which is working fine on windows. So please wait until someone make driver for it or my uncomplete project will finish

Ha, i just got a MiniPC with that Wifi Chip. Super sad to see that Mediatek doesn't support this chip on Linux.

• I tried it, it is not working. I will try if I can find something on it.

• Working but not connecting to internet

I've sent some PRs on the repo based on my finding on the Android BSP driver. You can check it out here

These are all untested btw, here's the PR I sent

I compiled your new code but my wifi doesn't respond on loading module. it gives error and when I restart my system it doesn't respond to wifi on insmod. Is it working on your system?

What do you mean doesn't respond ?

While testing this driver sometimes I saw this type of error and my mediatek wifi chip is gone from lspci list also. It comes to normal after several restart.

Have you tried transmitting every frame on the same TX queue/ring/etc as the management frames? Since the authentication and association frames are being transmitted successfully.
