Installing Vonger's Propietary mt7628.ko gives Kernel Panic

Sun Feb 11, 2018 11:56 am

So here we are again, I'm trying to make the propietary Wifi driver to work in Lede on my Vocore 2 Lite (Image and Module can be found here: http://vonger.cn/?p=14366). I'm trying to install the module manually (As the image does not works on Vocore 2 Lite and Vonger is unable to make a Vocore 2 Lite image). But when I'm trying to install the kernel module the whole system crashes with a Kernel Panic. Here is the output:

Anybody has a clue what is going on? Is there any way to make this finally work?

Hi,

I have built a version of OpenWrt with the latest 4.14 kernel and mt76 driver and the wifi is (at least for me) reliable enough. See here:https://github.com/amaumene/openwrt/releases/tag/beta1

I have created a new topic but it seems it needs to be approved first^^

I know that doesn't answer your initial question, but if you are looking for reliable wifi, this does the job.

Nice! That are good news! Does it work with Vocore 2 Lite?

That's issue might be memory problem, I will make a firmware for 64M and try later. Please check vonger.cn and search VoCore2 Lite later.

Any news on this, @Vonger?
