If unsure, say N. To compile this driver as a module, choose M here: the module will be called mini6410-ts. config TOUCHSCREEN_1WIRE tristate "Mini6410 1-Wire host and Touch Screen Driver" depends on MACH_MINI6410 help Say Y here to enable the 1-Wire host and Touch Screen driver for FriendlyARM Mini6410 development board. If unsure, say N. To compile this driver as a module, choose M here: the module will be called mini6410_1wire_host. vi arch/arm/mach-s3c64xx/mach-mini6410.c 44行 将#include <plat/ts.h> 改成#include <mach/ts.h> 320行将 static struct s3c2410_ts_mach_info s3c_ts_platform __initdata = { .delay = 10000, .presc = 49, .oversampling_shift = 2, }; 改成 static struct s3c_ts_mach_info s3c_ts_platform __initdata = { .delay = 0xFFFF, .presc = 0xFF, .oversampling_shift = 2, .resol_bit = 12, .s3c_adc_con = ADC_TYPE_2, }; 436行将 s3c24xx_ts_set_platdata(&s3c_ts_platform); 改成 s3c_ts_set_platdata(&s3c_ts_platform); vi arch/arm/plat-samsung/Makefile 60行 注释掉obj-$(CONFIG_SAMSUNG_DEV_TS) += dev-ts.o 不然会有multiple definition of `s3c_device_ts'的错误很奇怪，友善的源码CONFIG_SAMSUNG_DEV_TS=n，而我的源码出来后CONFIG_SAMSUNG_DEV_TS=y，还改不掉。。  vi drivers/input/touchscreen/mini6410-ts.c 增加头文件#include<linux/sched.h> 奇怪的是友善的mini6410-ts.c 里没这个头文件也能找到需要的东西。。。  Input device support ---> [*] Touchscreens ---> <*> S3C touchscreen driver for Mini6410 <*> Mini6410 1-Wire host and Touch Screen Driver lcd好用了，开机出现了那只小企鹅，挂NFS后触摸屏也能用了。
