WiFi module

Tankafaire

I have compiled the kernel with 8188eu with success:

1. [    1.594893] sw_usb_enable_hcd: usbc_num = 1
   
2. [    1.599783] usbcore: registered new interface driver rtl8188eu
   
3. [    1.611352] ehci_hcd: USB 2.0 'Enhanced' Host Controller (EHCI) Driver
   
4. [    1.623091] ohci_hcd: USB 1.1 'Open' Host Controller (OHCI) Driver

Copy code

But now I have to activate the USB wifi in fex.txt but it's a bit difficult...
I think I have to wait for a working script.bin !!

Hi

Can you post a step by step list What is to do to compile.
I come from windows and have no experience in linux.

Thank you

@Tankafaire I've this same result with bananian kernel (without modify). I've tried changing usbc_num in script.bin to 0,1,2 and wifi isn't showing in lsusb output nor in dmesg. Only info about loading driver.

EDIT:
Ok. After studying schematics I've finally found! Wifi is default disabled (power supply for wifi module is switched off). To use onboard module You must pull up PH22 CPU pin.
GUIDE TO MANUAL RUN WIFI ON UNMODIFIED BANANIAN:
1. Download script.bin https://drive.google.com/file/d/ ... 3c/view?usp=sharing
2. Replace original /boot/script.bin with downloaded
3. Reboot OrangePi
4. Do as root:

1. echo 89 > /sys/class/gpio/export
   
2. echo out > /sys/class/gpio/gpio89/direction
   
3. echo 1 > /sys/class/gpio/gpio89/value

Copy code

From now You should have onboard wifi working. You should see in dmesg output something like this:

1. 
   
2. [  178.771388] ehci_irq: port change detect
   
3. [  179.053845] usb 3-1: new high-speed USB device number 2 using sw-ehci

Ok, I never found the solution alone ! Thanks for sharing, I will try this.

ryba84

If You want to automatically enable onboard wifi during boot add commands from guide to Your /etc/rc.local. We must prepare proper script bin for our board.

Tankafaire

Yeah it work !
I have done this:

1. echo "89" | sudo tee /sys/class/gpio/export
   
2. echo "out" | sudo tee /sys/class/gpio/gpio89/direction
   
3. echo "1" | sudo tee /sys/class/gpio/gpio89/value

Copy code

and

1. $ lsusb
   
2. Bus 001 Device 002: ID 1a40:0101 Terminus Technology Inc. 4-Port HUB
   
3. Bus 003 Device 002: ID 0bda:8179 Realtek Semiconductor Corp.
   
4. ...

Copy code

Thanks

It's ok too, with the lines inside /etc/rc.local, but wifi is available after ~1min:

11. [   89.908450] udevd[303]: renamed network interface wlan0 to wlan1

Copy code

You can see between 26s and 89s there's nothing (dmesg after 5 min)
Also, wlan0 is renamed to wlan1, but it's not very important I suppose.
I havn't configured wifi yet.

You using original bananian image? I've using only bananian kernel (my kernels don't work and I have no clue why) on my Debian Jessy image, and wifi is showing up on 36s. I wonder if we could default enable wifi in script.bin. This should speed up things.

Tankafaire

Yes, it's a compiled kernel, 3.4.105+
I will try to modify script.bin to see if something change.
Edit:
wifi works!

But I must to wait about 80s to make the sudo service networking restart command
