Finally, Able to load ra0 with mt7601u. I have followed following Threads with linux_bananapi 3.4.90 kernel:

http://www.raspberrypi.org/forums/viewtopic.php?p=392591#p392591   // for building the module mt7601usta

&

http://forum.lemaker.org/viewthread.php?tid=1817&highlight=coherent  // for coherent_pool error in dmesg

I am able to connect to my router but no internet through ra0. Can someone help ?

I have setup /etc/network/interfaces for ra0.

   I have fixed it. Issue was default gateway was not getting set for ra0. So made following modification & it worked:
iface ra0 inet static
        address 192.168.1.201
        netmask 255.255.255.0
        geteway 192.168.1.1
        up route add gw 192.168.1.1

Hi,
rbarua, can you explain me how to create the folder /lib/modules/3.4.90/build please ?
or maybe make a tutorial with the step you had to do to compile the driver ...
I've the same wifi dongle, and i can't success to make the driver for this kernel !
THX

   Assuming you can connect to eth0 for getting internet on your Bananapi board:
   sudo git clone https://github.com/LeMaker/linux-bananapi  /usr/src/linux_bananapi
   ln -s /usr/src/linux_bananapi /lib/modules/3.4.90/build

   If you cant connect to eth0, then download from git and copy it to your sdcard. And link it as mentioned above to your build.

You could try this...
cd into your linux source directory.

1. make mrproper

Copy the Code

then copy over the .config file (zcat /proc/config.gz > /my_kernel_source_dir/.config)
you may also copy over the Module.symvers file provided by Tony in another thread.

1. make menuconfig

Copy the Code

1. make prepare

Copy the Code

1. make scripts

Copy the Code

Now try and compile your driver.

Hi !
Still no working GGGGRRRRR !!

#sashjoseph, With your advice, i'm now able to compile the driver ( I just had to install libncurses)
But if i try instmod mt7601Usta.ko , i get a " invalid format".
In my makefile, the platform is set for PC, is it right ?

#Rbarua, I can "insmod ..." your file but it dont work for me.

The ifconfig command show only ETH0 and lo .

there is an error returned by the dmesg command :
