MT7601 on Raspberry Pi

Here's how to cross compile driver for Mediatek MT7601 based wifi dongle.

Before this, you need to compile your own raspibian kernel, see my old post: http://igunosystem.blogspot.co.id/2014/03/step-by-step-building-raspibian-on.html
After above process is OK, You'll have compiled kernel source and working root file system with working chroot (using qemu-arm-static) for raspberry pi board on your Desktop PC.

mt7601
download source:
https://github.com/porjo/mt7601/archive/master.zip
or
git clone https://github.com/porjo/mt7601.git
edit Makefile

ifeq ($(PLATFORM),PC)
# Linux 2.6
LINUX_SRC = [linux_source_dir]
# Linux 2.4 Change to your local setting
#LINUX_SRC = /usr/src/linux-2.4
LINUX_SRC_MODULE = [rootfs_dir]/lib/modules//kernel/drivers/net/wireless
CROSS_COMPILE = [toolchains_dir]/bin/arm-linux-gnueabihf-
ARCH=arm
export ARCH
export CROSS_COMPILE
endif

Compile It using:
make

To Install, see the install part on Makefile
install:
    rm -rf $(DAT_PATH)
    $(shell [ ! -f /etc/Wireless ] && mkdir /etc/Wireless)
    mkdir $(DAT_PATH)
    cp $(RT28xx_DIR)/$(DAT_FILE_NAME) $(DAT_PATH)/.
    install -d $(LINUX_SRC_MODULE)
    install -m 644 -c $(addsuffix .ko,$(MOD_NAME)) $(LINUX_SRC_MODULE)
    /sbin/depmod -a ${shell uname -r}

Now copy the RT2870STA.dat & mt7601Usta.ko to somewhere in your running raspberry system or chroot to raspberry folder with qemu-arm-static then do

mkdir /etc/Wireless/RT2870STA
cp RT2870STA.dat /etc/Wireless/RT2870STA/.
install -d /lib/modules/$(uname -r)/kernel/drivers/net/wireless/
install -m 644 -c mt7601Usta.ko /lib/modules/$(uname -r)/kernel/drivers/net/wireless/
depmod -a $(uname -r)

You can get my working copy of pre-compiled kernel 3.14y including working mt7601 & rtl8188eu driver from here:

Copy to your RaspberryPi SD Card somewhere, extract it, and forced copy to root folder, then reboot with wifi dongle plugged, you should see the ra0 in ifconfig.
