MT7612U driver is not working. #3014

qtopie · 2019-06-16T11:35:40Z

Describe the bug
I wanted to use a wifi dongle on raspberry pi 3 with mt7612u driver, but failed to make it work.

To reproduce

Fresh install latest stretch-lite image and update kernel : 4.19.42-v7+
Download mt7612u wifi driver bin file into /lib/firmware
Insert wifi dongle, and run sudo usb_modeswtich ... command to switch into wifi mode.
Run ifconfig and dmesg to see results.

Expected behaviour
New wlan interface should show up, and no errors in dmesg messge.

Actual behaviour
No new wlan interface can be found, and dmesg got:

Where exactly is the driver from?

qtopie · 2019-06-16T15:57:58Z

The driver is included in the firmware, installed by sudo apt dist-upgrade. see #2890. And bin file is from https://github.com/ulli-kroll/mt7612u/tree/master/mcu/bin. I've checked mt7612u is working on ubuntu 18.04 x64 on my laptop

ghost · 2019-06-16T16:09:01Z

Does it work with the stock vendor supplied firmware, or is that the same as the one on that github repo?

qtopie · 2019-06-16T16:14:30Z

I've tried both, neither is working on raspberry pi. But bin files can work on my laptop.

lategoodbye · 2019-06-17T16:19:04Z

This driver has been introduced with 4.19 and still contains a lot of bugs for non-x86 platforms.
Are you able to test rpi-5.1?
Which wifi dongle are you using?

cybex-dev · 2019-06-17T21:18:44Z

I have the same problem as @artificerpi.

I have posted the module (driver) code on my github - cybex-dev. This is the module code given by the manufacturer, as is.

Please note however that the manufacturer code does not seem to compile correctly.

cybex-dev · 2019-06-22T17:58:42Z

any updates for us?

qtopie · 2019-06-26T13:24:58Z

@lategoodbye Thanks. It works on rpi-5.1.y

I heve the same issue
@artificerpi How do I install "rpi-5.1.y" ?

I have a Raspberry Pi 2B kernel 4.19.59-v7+

pelwell · 2019-07-24T19:25:46Z

You would have to build it yourself (see https://www.raspberrypi.org/documentation/linux/kernel/building.md), but if someone can identify the necessary commits (and if they cherry-pick successfully) we would be open to back-porting them to rpi-4.19.y.

lategoodbye · 2019-07-24T19:44:44Z

The driver was / is under heavy reworking, so i expect a lot of changes between 4.19 and 5.1.

Y2Kot · 2019-09-18T08:59:21Z

I've update my kernel to 5.1 version, however I got

how can I install driver on 5.1 kernel? It's raspberry pi4

pelwell · 2019-09-18T09:06:56Z

You have an MT7610, not an MT7612U, so this is the wrong place for your question. However, the Linux firmware repo appears to have firmwares that should work: https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/mediatek

Y2Kot · 2019-09-18T09:11:26Z

sorry. My wrong. Two last questions: how can I install bins from you url? And should I update to 5.3 to make it work?

pelwell · 2019-09-18T09:21:48Z

In your browser, click on the file you want, then click on '(plain)' to download it. And stay away from 5.3 for now - it's not really ready yet; 5.2 should be fine.

kmahyyg · 2019-10-16T03:33:07Z

I can confirm that there must be some necessary modification in Kernel, at least version 5.3 is what we want.

EDUP AC-1616 (MT7612U confirmed by manufacturer) is working only on my laptop with Arch Linux with kernel 5.3.6, none of my friends' 5.2.0 (don't work at all) or 4.19 in raspbian(no AP mode support) is working.

So may I ask if there's any support chart or progressing chart for 5.3.x kernel? Can we have AP mode support in kernel 4.19.x in raspbian?

qtopie · 2019-10-18T15:22:59Z

@kmahyyg I think you should watch codes changes in upstream linux kernel . AP mode is not supported in 4.19.x, and it's not stable. I can confirm that starting from 5.1.12-v7+, mt7612u is working fine in Raspbian.

kmahyyg · 2019-10-18T16:14:33Z

@kmahyyg I think you should watch codes changes in upstream linux kernel . AP mode is not supported in 4.19.x, and it's not stable. I can confirm that starting from 5.1.12-v7+, mt7612u is working fine in Raspbian.

Thanks for your reply. That's why I comment here. I think there might be some schedule about the kernel upgrade in raspbian since rpi doesn't have mainline kernel support. Currently, except my RPI, all my devices were upgraded to 5.3.7 kernel. Sorry for disturbing. Thank you for your guys' hard work.

JamesH65 · 2019-10-19T07:29:37Z

We do run behind mainline and although there is a mainline kernel that is specifically for Pi, it doesn't have all the features we need for our devices, so we have to patch in all the required changes. That takes a while, to do it and to test it and to fix any problems, which is why we are on 4.19. Newer kernels are being tested. Not sure which is our next release, or when that will be. 5.3 is currently very flakey.

pelwell · 2019-10-19T07:50:32Z

If we had to ship a newer kernel today it would be 5.2. As James said, there are a few issues with our 5.3 fork.

evilhard2 · 2024-01-29T18:05:21Z

Hi
I installed kali linux on ORANGE PI 5. I updated kali. But I still have the same problem I can't get my alfa awuso36acm usb key to work.

When I am in a terminal and I type lsusb I see the mediatek mt7612u. but nothing wants to work.

Thanks you for helping me.
