Hi,

Tried to use ralink based card but no success. I installed firmware-ralink package but dmesg still is saying that firmware is missing.

The file it's looking for is present. What's the problem? Kernel driver bug?

You say it's easy to compile the drivers with kernel source code. where can I find a tutorial/video straight forward of this?

I just success WIFI Connection with RALink (ID 148f:3070 Ralink Technology, Corp. RT2870/RT3070 Wireless Adapter)

I used OrangePI-PC_Ubuntu_Vivid_Mate.img and re-compile the kernel by using source code from loboris (https://github.com/loboris/OrangePI-Kernel) and driver from mediatek (http://www.mediatek.com/en/downl ... 372-rt5572-usb-usb/)

After everything compiled and installed, I blacklist my old driver (rt2800) and use the new one with 'ifconfig ra0 up' and connect the network with 'nmtui-connect'

It's worked!!

I'm novice one, Some step may not make sense

1. Install 64bit version of Ubuntu on the virtual machine (amd64)
2. Install 'git-core', 'build-essential', 'u-boot-tools', 'libncurses5-dev'
3. Clone loboris repo. 'git clone https://github.com/loboris/OrangePI-Kernel'
4. I cut a new gen_check_code from http://moinejf.free.fr/opi2/kernel-3.4.patch (I attached gen_check_code at the attachment part) 5. Compile it 'gcc -o gen_check_code gen_check_code.c' and copy to 'YourPATH/OrangePI-Kernel/linux-3.4/arch/arm/mach-sunxi/power/brom/' and 'YourPATH/OrangePI-Kernel/linux-3.4/arch/arm/mach-sunxi/pm/standby'
6. Install 32bit library that toolchain needed.
  I install these packages  don't forget ":i386"
7. Goto OrangePI-Kernel, run
  Change anything you like, and don't forget to save before you exit

8. Run the compile script (


9. Take a cup of coffee, have breakfast or whatever you want until the compile process complete. If Error please check 'kbuild_2_.log'
10. After the kernel built, run
    to create script.bin for your OPI-PC
11. Check your 'YourPATH/OrangePI-Kernel/build', Files 'uImage_OPI-2' and 'script.bin.OPI-PC*' should be existed.
12. Copy those files into your SD-Card
13. Boot  to the system with your new uboot image. For the first boot many modules will failed because of mismatch kernel and modules version. I solved this issue and get the whole source code to my OPI-PC
     transfer the tar'ed file to your OPI-PC and unpack it. Navigate to 'OrangePI-Kernel/linux-3.4/output/lib' and copy everything to your '/lib' on OPI-PC
14. Run 'depmod -a 3.4.39-01-lobo' and reboot the OPI-PC
15. After the OPI-PC boot up. go to '/lib/modules/3.4.39-01-lobo', fix the soft linked files 'source' and 'build' to the correct path.
16. Download RT2800 from Mediatek 'http://www.mediatek.com/en/downloads1/downloads/rt8070-rt3070-rt3370-rt3572-rt5370-rt5372-rt5572-usb-usb/', You get '
DPO_RT5572_LinuxSTA_2.6.1.3_20121022.tar.bz2', unpack it!
17. Install some compiler on your OPI-PC
    ***If you get compile error in the future, Please try to install the missing.
18. To prevent the error, Please go to 'YOURPATH/OrangePI-Kernel/linux-3.4' after that, 'make clean' and 'make modules_prepare' to prevent 'modpost' and 'recordmcount' make your compile failed.
19. Go to your unpacked RT Driver in step 16 . Edit os/linux/config.mk
20. Do compile your driver. Many warnings appeared don't be panic.
21. 'depmod -a 3.4.39-01-lobo' again and edit your '/etc/modprobe.d/blacklist.conf'
22. Reboot your system and use 'dmesg' to verify the new driver loaded.
23. Turn the radio on with
24. Try to connect the WIFI by using NetworkManager
    If the WIFI works well, you will see some access points around you.

25. Enjoy!

=================
Some questions:
Q: Why I install 64 bit version of Ubuntu
A: Last time, the error of 'gen_check_code' and can't fix, no source code. Until I got the alternative version of it with source code but it take a time to re-install the system.

Q: How long that I use to make it work?
A: Around 1 week

!!! DON'T FORGET I AM A KIND OF NOVICE -- ERROR MAY OCCUR !!!

Yes, I am facing similar problem. Somehow the kernel is not able to find "Firmwares" and I think it is a user mode thing that is missing on the image.

Damn... I thought that all drivers included in this specific kernel version should work. No I can see I was very wrong. Every hardware I have ever tried was not working, except mouse, keyboard or storage. Even if appropriate module is present in kernel.

Sadly, OrangePI hardware is indeed great but software seems to be very poor. Old and broken kernel... not nice.

There are 2 different problems in what you say:
- some drivers are not generated in the gracefully offered and ready to use kernels (loboris),
- the kernel is old and broken.
For the 1st problem, you can get the kernel source and compile what you want. That's easy.
For the 2nd problem, yes, the Allwinner's kernel is a piece of shit, and they are waiting for the free software community to debug it. And we must do this job to have working machines. That's the hard law of business...

Wifi
are any wifi dongles supported under any available OS for the OPI-PC ?
Which ones?  And how to get wifi to work?
My answer:
this is the best distribution so far for me:http://www.orangepi.org/orangepi ... p;extra=&page=2

it works with my RTL8188 WIFI and Cambridge  BT dongles.
