kernel 3.0.36 source code -> rt2800usb.ko

[unissoft-bj]

https://launchpad.net/linux/+milestone/3.0.36

https://launchpad.net/linux/trunk/3.0.36/+download/linux-3.0.36.tar.gz

解决3.0.36 / 3.0.36+ moules版本问题： root@radxa:~/rt2x00# insmod rt2800usb.ko insmod: ERROR: could not insert module rt2800usb.ko: Invalid module format

可以用 modprobe –force 也可以修改 ： /usr/src/kernels/{your version}/include/generated/utsrelease.h and just add the ‘+’ sign to the end of the version number. E.g.

define UTS_RELEASE "3.3.0-xxx+"

And now all modules compiled against the kernel will load with no issues.

进入 linux-3.0.36

检查交叉编译环境

export ARCH=arm export CROSS_COMPILE=arm-linux-gnueabihf-

一个最简的配置，只保留rt2800usb相关内容

或者直接从github上复制.config

make menuconfig

编译

make 注意，有一个错误，不影响modules编译

在生成modules之前，修改版本号（经测试，不起作用） nano include/generated/utsrelease.h

define UTS_RELEASE "3.0.36+"

编译模块

make modules

安装模块到modules目录

mkdir modules make INSTALL_MOD_PATH=./modules modules_install

目标文件

修改处理器类型 armv7 http://forum.xda-developers.com/showthread.php?t=2231136

修改kernel version http://stevechui.blogspot.com/2011/10/compiling-kernel-modules-tunko-for.html

[unissoft-bj]

1，检查ihost上的kernel version root@radxa:~# uname -r 3.0.36+ root@radxa:~#

2，下载kernel source 3.0.36，cross compiler

3，复制linux-rockchip下的radxa_rock_linux_defconfig 到sourcecode/arch/arm/configs

4，make radxa_rock_linux_defconfig

5，make menuconfig

修改cpu类型 armv7 修改smp 增加ralink rt2800usb driver

6，修改.config CONFIG_CROSS_COMPILE="arm-linux-gnueabihf-" CONFIG_LOCALVERSION="+"

7，修改 scripts/setlocalversion

echo "+" -> echo ""

8，make modules

9，mkdir modules make INSTALL_MOD_PAHT=./modules modules_install

10， modinfo rt2800usb.ko

11，复制 root@radxa:/home/rock/rt2x00# ls -l total 144 -rw-r--r-- 1 rock rock 44737 Apr 30 09:05 rt2800lib.ko -rw-r--r-- 1 rock rock 36641 Apr 30 09:05 rt2800usb.ko -rw-r--r-- 1 rock rock 46105 Apr 30 09:05 rt2x00lib.ko -rw-r--r-- 1 rock rock 14675 Apr 30 09:05 rt2x00usb.ko

12，复制github board2ihost branch rocklit 下 rt5370下 cp rt2870.bin.029 /lib/firmware/rt2870.bin

13，insmod root@radxa:/home/rock/rt2x00# insmod rt2x00lib.ko root@radxa:/home/rock/rt2x00# insmod rt2x00usb.ko root@radxa:/home/rock/rt2x00# insmod rt2800lib.ko root@radxa:/home/rock/rt2x00# insmod rt2800usb.ko
