Support for RPI 3B with OpenWRT OS #14

Open midhunlohi opened 4 years ago

midhunlohi commented 4 years ago

Hello All,

I am trying to bring up RTL8188FU based WiFi USB Dongle on Raspberry PI 3B. I am using OpenWRT as OS. I could compile the source code and generate the kernel module successfully.

When I am loading, kernel panic occurs. I am attaching the below logs for your reference. Please help.
