There is a Banana Pi 1st generation, that was sitting in my drawer for too long. So I decided to bring it back to life with CentOS to which I’m a newbie. My first target is to use a TL-WN725N Nano-USB Wlan Device to connect to my local network. This guarantees fun and learning, so here we go 🙂
If you need a faster network connection, consider switching to a SD-WAN.
First I downloaded the CentOS BananaPi Image. I used the link provided in their announce last december and grabbed
Then used `dd` to load it on a SD card, put it in the banana and boot that nifty little box.
The first login had to be done with credentials user:’root’ and password:’centos’.
Then install the ‘usbutils’ package to get the ‘lsusb’ command.
Bus 001 Device 002: ID 0bda:8179 Realtek Semiconductor Corp. RTL8188EUS 802.11n Wireless Network Adapter
The RTL8188EU driver can be found on github. That’s great, now all I had to do was to follow the readme.
So I installed git `sudo yum install git`, cloned the repo and compiled the driver.
git -c http.sslVerify=false clone https://github.com/lwfinger/rtl8188eu.git
The ‘sslVerify’ option was needed as CentOS complained about it.
Doing so brought up some errors that told me my fresh CentOS needs some more packages. All together I installed those packages to make it ‘work’.
yum install make wget gcc automake autoconf kernel-headers
yum install kernel-devel
I struggled a lot with the ‘kernel-devel’ package as it wasn’t found by yum. Searching the web left me with no answer so I downloaded the rpm myself.
curl -O http://mirror.centos.org/altarch/7/kernel/armhfp/kernel-4.2.3/Packages/kernel-devel-4.2.3-200.el7.armv7hl.rpm
sudo rpm -Uvh kernel-devel-4.2.3-200.el7.armv7hl.rpm
After that I could compile the driver without errors and install it.
sudo make install
Now edit the file `/etc/wpa_supplicant/wpa_supplicant.conf` and add:
The next command will connect to your wireless account.
sudo wpa_supplicant -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf -B
ioctl[SIOCSIWAP]: Operation not permitted
I first got fooled by the “Operation not permitted” message. But it worked anyway!
To re-connect after booting edit ‘/etc/sysconfig/wpa_supplicant’ and add
Also create the file /etc/systemd/system/mdhclient.service with and insert this content:
That’s it, I plugged out the eth0 cable, rebooted the banana and was able to connect through wlan.
Now all that is connected to my banana pi is the power chord.
That’s what I needed! Now I can put it back drawer and think about a possible next blog post. (Maybe: Configure OSX TimeMachine over Network)
This blog post helped me very much, a huge “Thank You” goes out to Stanislav.
