rt2860v2-for-openwrt-mt7620
rt2860v2_ap/rt2860v2_sta driver for openwrt trunk(3.10.x kernel) on MT7620 SOC. (Test on mt7620n 16m flash + 64M ram) 1. go and get the sources of openwrt trunk:
svn co svn://svn.openwrt.org/openwrt/trunk/ ~/openwrt.trunk/trunk cd ~/openwrt.trunk/trunk/ ./scripts/feeds update ./scripts/feeds install meshwizard openssh-server openssh-client ./scripts/feeds install freifunk-common freifunk-gwcheck freifunk-mapupdate ./scripts/feeds install luci luci-app-meshwizard luci-app-olsr luci-app-olsr-services ./scripts/feeds install luci-app-olsr-viz luci-app-freifunk-policyrouting luci-mod-freifunk ./scripts/feeds install luci-theme-freifunk-generic olsrd olsrd-mod-txtinfo olsrd-mod-dyn-gw ./scripts/feeds install olsrd-mod-dyn-gw-plain olsrd-mod-dot-draw ./scripts/feeds install olsrd-mod-arprefresh olsrd-mod-watchdog olsrd-mod-tas olsrd-mod-httpinfo ./scripts/feeds install olsrd-mod-pgraph olsrd-mod-secure olsrd-mod-bmf ./scripts/feeds install luci-app-upnp minidlna miniupnpc miniupnpd luci-app-minidlna rtorrent ./scripts/feeds install usb-modeswitch usb-modeswitch-data usbutils multiwan ./scripts/feeds install 6in4 6rd 4th 6to4 6tunnel libdaemon aprx usb-modeswitch ./scripts/feeds install asterisk18 kamailio4 ./scripts/feeds update -a ./scripts/feeds install -a
$make defconfig $make menuconfig
Select the following configuration------
Target System: (Ralink 288x/3xxx) Subtarget: (MT7620N based boards)
$make V=99
Wait make command to be done.
When make finished. The firmware will be in the directory: $HOME/openwrt/openwrt-trunk/bin/ramips/
Then, you can download and burn the new firmware to the mt7620 SOC Board via TFTP in the uboot stage.
But, unfortunately, that default configuraion don't has wifi driver support,
So We cann't startup a Hotspot on our MT7620 SOC for incoming connections from Smartphones and laptops.
All steps above are the default configuarions from the openwrt official site. 3.Now, I will guide you to port rt2860v2_ap driver to the kernel tree and build it to fix that problem.
$cd ~/
$git clone https://github.com/wuqiong/rt2860v2-for-openwrt-mt7620.git
$cp -r rt2860v2-for-openwrt-mt7620/ralink ~/openwrt/openwrt-trunk/build_dir/target-mipsel_24kec+dsp_uClibc-0.9.33.2/linux-ramips_mt7620n/linux-3.10.28/drivers/mtd/
$cp -r rt2860v2-for-openwrt-mt7620/rt2860v2 rt2860v2-for-openwrt-mt7620/rt2860v2_ap ~/openwrt/openwrt-trunk/build_dir/target-mipsel_24kec+dsp_uClibc-0.9.33.2/linux-ramips_mt7620n/linux-3.10.28/drivers/net/wireless/
After copied the driver code to the building kernel tree. Then, Let's to add Kconfig and Makefile objs in each directory of "mtd" and "wireless".
Add the following line before the end of Kconfig file:~/openwrt/openwrt-trunk/build_dir/target-mipsel_24kec+dsp_uClibc-0.9.33.2/linux-ramips_mt7620n/linux-3.10.28/drivers/mtd/Kconfig
source "drivers/mtd/ralink/Kconfig"
Add the following line before the end of makefile:~/openwrt/openwrt-trunk/build_dir/target-mipsel_24kec+dsp_uClibc-0.9.33.2/linux-ramips_mt7620n/linux-3.10.28/drivers/mtd/Makefile
obj-$(CONFIG_MTD_RALINK) += ralink/
Add the following line before the end of Kconfig file: ~/openwrt/openwrt-trunk/build_dir/target-mipsel_24kec+dsp_uClibc-0.9.33.2/linux-ramips_mt7620n/linux-3.10.28/drivers/net/wireless/Kconfig
source "drivers/net/wireless/rt2860v2_ap/Kconfig"
Add the following line before the end of makefile: ~/openwrt/openwrt-trunk/build_dir/target-mipsel_24kec+dsp_uClibc-0.9.33.2/linux-ramips_mt7620n/linux-3.10.28/drivers/net/wireless/Makefile
obj-$(CONFIG_RT2860V2_AP) += rt2860v2_ap/
4. Okey, Driver Code Configuration Finished.
Go back to the ~/openwrt/openwrt-trunk directory. And run the shell command:
$make kernel_menuconfig
Enter this menu:
A:

We select "*" to building the driver into the kernel, not a kernel module.
After selecting the configration. save and exit menuconfig. 5.Now. Just Hit "Make V=99" to build.
we have added and configured the wifi driver code to the kernel build tree.
just type the make V=99 command in directory:~/openwrt/openwrt-trunk ,
$make V=99
And wait for some minutes to be builded. 6. After builded, burn the new firmware with wifi driver.
You will found out that, wifi device ra0 will be appeared.
test with:
ifconfig ra0
But your cann't successfully ifconfig ra0 up.
Because we lack the /etc/Wireless/RT2860/RT2860.dat file(or symbol link to /tmp/RT2860.dat),
Which generated by an scripts file in /lib/wifi directory which first introduced by lintel.
7. Enjoy DIY with your hands.
I will not provide the dat file or script file. you need to scratch up those file by yourself.
Last commit, I havn't shared the script file.
This Time, I shared the script file named: rt2860v2.sh.
I fixed the wrong default mac address problem via shell command in this script file, you know, it's not the best, but works well.
Your can define your perefered mac addres in /etc/config/wireless file with option macaddr '1a:1a:1a:1a:1a:1a';
Or you can read out the factory default mac address in eeprom, using this shell:
hexdump -s 4 -n 6 -C /dev/mtd2 | head -n 1 | sed 's/\ \ /:/g' | cut -d: -f 2 | sed 's/\ /:/g'
substitute and eval this shell in the appropriate place in rt2860v2.sh file. you can get everything automatically. Where is the best and perfect firmware? I will not to Share out any more. Dive into the code and fix it by yourself, it's so easy. 8. Say thanks to me as much as you can.
sorry for these Chinglish, wish you can read it.
