[HELP] WIFI dongle MT7601U driver compile problem ...

Hi all
I tried to compile MT7601U driver on newest Lubuntu v3.1.1 image of Banana Pi
after the compile procedure has done , I run the command :
# modprobe -v mt7601Usta
and I will always get the message :
insmod /lib/modules/3.4.90/kernel/drivers/net/wireless/mt7601Usta.ko
modprobe: ERROR: could not insert 'mt7601Usta': Exec format error
I was so confusing ... What's going on ? then I check the /var/log/dmesg
there is the related message line :
[ 9.458199] mt7601Usta: no symbol version for module_layout
I don't know what happend ? I tried to search google by the given message above
but I didn't find a simple solution
and below are the steps I used to compile the mt7601Usta driver
[install the prerequisites]
# apt-get install linux-headers-generic build-essential
# apt-get install git
[get the kernel source (I'm not sure the source is 'kernel source' or something else ...)]
# cd /usr/src
# mkdir kernel
# cd kernel
# git clone https://github.com/LeMaker/linux-bananapi
# ln -s /usr/src/kernel/linux-bananapi /lib/modules/3.4.90/build
# cd linux-bananapi
checkout the branch ... is this step needed ???
# git branch -avv
# git checkout voice/sunxi-v3.4.90-r1_bananapi
# make mrproper
# gzip -dc /proc/config.gz > .config
# make modules_prepare
then I have downloaded the MT7601U driver source from
http://www.mediatek.com/en/downloads/mt7601u-usb/
# cd /home/bananapi/Downloads
# mv DPO_MT7601U_LinuxSTA_3.0.0.4_20130913.tar.bz2 /usr/local/src
# cd /usr/local/src
# tar xvjf DPO_MT7601U_LinuxSTA_3.0.0.4_20130913.tar.bz2
# cd DPO_MT7601U_LinuxSTA_3.0.0.4_20130913
# make
# make install
yes! after these steps I will finally get my MT7601U module at
/lib/modules/3.4.90/kernel/drivers/net/wireless/mt7601Usta.ko
but this mt7601Usta.ko is not working
I cannot use it , everytime when I execute the command :
# modprobe -v mt7601Usta
I will always get the output messages from termial:
insmod /lib/modules/3.4.90/kernel/drivers/net/wireless/mt7601Usta.ko
modprobe: ERROR: could not insert 'mt7601Usta': Exec format error
RRRRRRRRR why ? I don't understand why ?
I cannot figure out this problem , any suggestion ?
救命！誰會在Banana Pi上面把MT7601U的驅動程式編譯出來呢？可以分享一下過程嗎？感激不盡
我是用最新的Lubuntu v3.1.1的影像檔開機的 |

here I bought the USB WIFI dongle
http://detail.tmall.com/item.htm?id=36988661875&toSite=main
because the seller's webpage says the product ID is WD-1511N
and I am so sure the WD-1511N is RTL8188eu chipset inside
so I bought it
but WUWUWUWWUWU when I plug it into my laptop
and run the command
# lsusb
I got this:
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 005: ID 148f:7601 Ralink Technology, Corp.
Bus 001 Device 004: ID 0a81:0101 Chesen Electronics Corp. Keyboard
Bus 001 Device 003: ID 093a:2510 Pixart Imaging, Inc. Optical Mouse
Bus 001 Device 002: ID 1a40:0101 Terminus Technology Inc. 4-Port HUB
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
can you see that '7601 Ralink Technology, Corp'
I want to buy RTL8188eu but when it's it's arrived finally I got a MT7601U
so if I can not compile the driver succussfully
the only choice I just let the MT7601U go to the trash can
or go to the big ocean ... bala bala because It become useless for me
各位高手和大俠們請幫忙，不然我也只能把這USB WIFI dongle丟了，唉 |

as I expected , nobody reply me , I SOLVED the compilation problem
I put the 'Module.symvers' into the dir /lib/modules/3.4.90/build
then I compiled the mt7601Usta.ko again , This time the compiled
mt7601Usta.ko is good , when I execute
# modprobe -v mt7601Usta
it will be successfully loaded without any error message
and I excute
# lsmod
I will see

yes ~ everything looks so fine , BUT when I excute
# ifconfig -a
I cannot get wlan0 or ra0 interfaces , this is the output messages ..

and I check /var/log/dmesg again
I found something strange here :
[ 9.227826] rtusb init rt2870 --->

[ 9.356707] rt2870: probe of 1-1:1.0 failed with error -1
[ 9.361393] usbcore: registered new interface driver rt2870
and I realize ONE THING , this USB WIFI dongle use mt7601Usta module as his driver
but why it has another name called rt2870 ???
is that mean rt2870 = mt7601u ?????
I also realize when I extract the driver source tar file
(DPO_MT7601U_LinuxSTA_3.0.0.4_20130913.tar.bz2)
I change into DPO_MT7601U_LinuxSTA_3.0.0.4_20130913 directory and look around
I found the file such like RT2870STA.dat RT2870STACard.dat ...
and after command 'make install'
there is a /etc/Wireless/RT2870STA/RT2870STA.dat inside my Lubuntu system on Banana Pi
so are both mt7601u and rt2870 mean the same stuff ?
they are the same ? no difference between them ? Just like You can call Iron man
Hey Iron man
or
Hey Tony
or
Hey Stark
is that mean ?
because actually 'Iron Man' = 'Tony' = 'Stark' just like 'rt2870' = 'mt7601u'
am I right ?
ok ... I keep researching for solve this problem
where is my wlan0 interface even through the lsmod command looks like successfully loaded mt7601Usta
我英文超爛請勿見怪，哈哈，看得懂就好了 |

When you complied a driver, if the driver is related to something in the kernel, you' d better replace all kernel and modules.
Now can you work with mt7601u? |

It seemed to for a short moment and then everything broke down so I am rebuilding the SD image again. This is both time consuming and frustrating. |

I have one similar Wifi adapter. It uses the same ID 148f:7601 ... I could compile the driver without a problem. I needed to add ID to the driver (mt7610sta) and I got ra0. When start using it kernel crashes.
Adaptor is working well with Windows 7, recognized as Wireless N adapter with driver pack for RT2870. |
