There are 2 different problems in what you say:
- some drivers are not generated in the gracefully ...

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 put here some instructions on how you may generate a kernel on your OPI2/plus/PC.

Generating on an other computer is more complicated, asking for a cross-compiler and SD card manipulation...

But ralink drivers are already included and already compiled. Any reason for compiling them again?

kernelpanic

The kernel modules are compiled, and they load. The problem seems to be somewhere in userspace, as the module can not find the firmware for the card, even though it is located within /lib/firmware. I do not know where, or if there is a place to specify where the firmware files are located.

I tested 4 ralink cards models. Some of them are unable to load firmware, some others cause module segmentation fault. None worked.

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!!

Care to post a guide?

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.

1. dpkg --add-architecture i386
   
2. apt-get update

Copy code

  I install these packages

1. gcc-5-base:i386
   
2. libc6:i386
   
3. libc6-dev:i386
   
4. libc6-dev-i386
   
5. libc6-i386
   
6. libgcc1:i386
   
7. libgpm2:i386
   
8. libncurses5:i386
   
9. libtinfo5:i386
   
10. linux-libc-dev:i386
    
11. zlib1g:i386
    
12. zlib1g-dev:i386

Copy code

  don't forget ":i386"
7. Goto OrangePI-Kernel, run

1. ./config_linux_kernel.sh

Copy code

  Change anything you like, and don't forget to save before you exit

8. Run the compile script (

1. ./build_scripts.sh 2                ## 2 - is for OPI2 and OPI-PC

Copy code

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

1. ./build_scripts.sh

Copy code

    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

1. tar cvzf orangepi.tgz  YourPATH/OrangePI-Kernel/

Copy code

     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.

1. rm -f source build
   
2. ln -s YOURPATH/OrangePI-PC/linux-3.4 build
   
3. ln -s YOURPATH/OrangePI-PC/linux-3.4 source

Copy code

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

1. apt-get -y install gcc make

Copy code

    ***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

1. HAS_WPA_SUPPLICANT=y
   
2. HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=y

Copy code

20. Do compile your driver. Many warnings appeared don't be panic.

1. make
   
2. make install

Copy code

21. 'depmod -a 3.4.39-01-lobo' again and edit your '/etc/modprobe.d/blacklist.conf'

1. blacklist rt2800usb
   
2. blacklist rt2800lib
   
3. blacklist rt2x00usb
   
4. blacklist rt2x00lib

Copy code

22. Reboot your system and use 'dmesg' to verify the new driver loaded.
23. Turn the radio on with

1. ifconfig ra0 up

Copy code

24. Try to connect the WIFI by using NetworkManager

1. nmtui-connect

Copy code

    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 !!!
