1. 修改drivers/input/touchscreen/下的Makefile
#obj-$(CONFIG_TOUCHSCREEN_S3C2410) += s3c2410_ts.o
obj-$(CONFIG_TOUCHSCREEN_S3C2410) += s3c_ts.o
2. 修改.config，找到CONFIG_TOUCHSCREEN_S3C2410，修改為
# CONFIG_TOUCHSCREEN_ILI210X is not set CONFIG_TOUCHSCREEN_S3C2410=y # CONFIG_TOUCHSCREEN_GUNZE is not set
3. make uImage
4. 下載新內核，啟動開發板，cd /mnt
5. cd ts_dir
6. cp * / -rfd
7. sh tslib.sh
8. 執行ts_calibrate以及ts_test，成功
/mnt # ts_calibrate
