Fixing WiFi on BananaPi Pro

Post by twisty » Sat Feb 03, 2018 4:32 am

Recently was turned on to DietPi through a YouTube video where it was recommended for use with ownCloud. I encountered issues with the wifi initially and found a simple, easy fix. I am posting this for my own record and if others encounter the same issue.

I wanted to try it out on my BananaPi Pro (armv71). Installed and started working on the first try, except the Wifi. I could enable WiFi through dietpi-config but ifup would fail lsmod did not show the device having loaded.

Initially I found older articles that advised that the ap6221 driver needed to be loaded. I started hunting around and found some odd methods to patch this through github. This did not feel like the right solution yet I did try the solutions I had found, none of them worked.

Looking into dmesg further, I noticed errors surrounding brcmfmac43362-sdio.txt not being found or loaded. Further investigation lead me to check the /lib/firmware/brcm/ folder and I could here find brcmfmac43362-sdio.bin yet no txt file.

I found a copy of the file in the bananian distro: ... 2-sdio.txt

I ran the following commands:

Code: Select all

cd /lib/firmware/brcm/
The wifi worked upon bootup.

If you are looking to use WiFi out of the box, here are (Optional) steps you can take:

Pre-configure Wifi Details for DietPi on BananaPi Pro
- Goto my computer, select the SD card and open it.
- Locate the folder boot, find the file dietpi.txt, and open it with Wordpad (Notepad++, or your editor of choice).
- Set Wifi_Enabled=1.
- Enter your ssid Wifi_SSID=MySSID and Wifi_KEY=MyWifiKey (both are case sensitive).
- Save the file.
- Locate the folder lib/firmware/brcm/ and create a new file with your editor called brcmfmac43362-sdio.txt.
- Navigate to ... 2-sdio.txt in your web browser.
- Select All and Copy the content.
- Paste the content into your editor and save the file.


Code: Select all
