We’re debuging the MT6625 wifi module driver, now it’s working at 2.4G, please check below link for details.
Good Job:grinning:
Great! Looking good.
Some code remarks, which GCC7 errors about:
In file ‘drivers/misc/mediatek/connectivity/wlan/gen2/os/linux/gl_p2p.c’ on line 3039:
iwe.u.data.length = 8 + sizeof("p2p_cap=");
should be:
iwe.u.data.length = 9 + sizeof("p2p_cap=");
because: “p2p_cap=%02x%02x%02x%02x%c” on line 3043 is 2+2+2+2+1 bytes long
Same issue also on line 3055 
Compiling and testing now, will come back with results!
Edit: Hm i seem to end up in some kind of deadlock:
WARNING: CPU: 3 PID: 0 at kernel/watchdog.c:352 watchdog_timer_fn+0x1bc/0x388()
I did copy the firmware files to /etc.
Edit 2: I managed to circumvent the deadlock by disabling CONFIG_MTK_COMBO_BT in the kernel config.
Now the wlan0 device shows up! Didn’t try to scan or connect yet.

Thanks, BitMaster.
I will check these errors. And I found the iwlist can’t show all available wifi AP, so I usually use wpa_supplicant to connect AP.
Let me know if you have any question.
I am not sure how I got the deadlock (watchdog trigger) yesterday, but I’ve tried several configuration options and I am no longer able to reproduce it. It now works for me with mt7623n_evb_bpi_defconfig (and some GCC7 patches). It might have been related to: https://github.com/BPI-SINOVOIP/BPI-R2-bsp/issues/5
I tried a WiFi scan with wpa_supplicant, but i don’t have an antenna yet. It does find my home network though, which is very close.
I have some questions:
- Will you eventually add the fairly cumbersome initialization sequence to the kernel?
- Do you appreciate pull requests?
Hi BitMaster,
Do you have the log for deadlock issue? If yes, can you share it with me?
For your questions:
- I don’t have plan to add the initialization sequence to kernel, but I will make a script for them, is it okay for you?
- Any pull request is appreciated, but please let me know what issue is fixed, so I’ll test it in next release.
Thanks Gary
The wifi module works fine at 5G mode, please see https://github.com/BPI-SINOVOIP/BPI-R2-bsp/issues/1 for details. But there is a balance issue at 5G mode, will focus on this issue right now
