AllWinnerTech A10添加驱动ko模块方法


【1】添加Linux触摸屏驱动:
添加驱动代码文件:
lichee\linux-2.6.36\drivers\input\touchscreen\mg-i2c-ts.c
lichee\linux-2.6.36\drivers\input\touchscreen\mg-i2c-ts.h

kconfig文件lichee\linux-2.6.36\drivers\input\touchscreen\Kconfig添加:
config TOUCHSCREEN_MG_I2C
 tristate "Morgan multi-touch device"
 depends on I2C
 help
   Say Y here if you have a Morgan multi-touch device

   If unsure, say N.
  
Makefile文件lichee\linux-2.6.36\drivers\input\touchscreen\Makefile添加:
obj-$(CONFIG_TOUCHSCREEN_MG_I2C) += mg-i2c-ts.o

编译内核:
./build.sh -p sun4i_crane


【2】Android2.3.4\device\softwinner\crane-evb-v13\mkfs.sh添加
cp $DRV_DIR/mg-i2c-ts.ko $PRODUCT_ROOT/drv/mg-i2c-ts.ko

【3】android启动文件init.sun4i.rc注释和添加
 #insmod /drv/ft5x_ts.ko
 insmod /drv/mg-i2c-ts.ko
 
串口输出调试信息
 在文件tools\crane-win-v2\wboot\bootfs\linux\params添加loglevel=8
 console=ttyS0,115200 root=/dev/nandb rw init=/init mem=448M@0x40000000 fbmem=32M@0x5a000000 loglevel=8;
