我最近在ARM4412的板子上移植Qt/Embedded，但是移植完成后在进行屏幕的校准时输出
xres = 800, yres = 480
selected device is not a touchscreen I understand
Took 4 samples...
Top left : X = -9636140 Y = 1
Took 4 samples...
Top right : X = -9636140 Y = 1
Took 4 samples...
Bot right : X = -9636140 Y = 1
Took 4 samples...
Bot left : X = -9636140 Y = 1
Took 4 samples...
Center : X = -9636140 Y = 1
ts_calibrate: determinant is too small -- 0.000000
Calibration failed.
但是同事已经确认我的屏幕肯定是没有问题的，我后来用同事可用的程序进行试验，当我用同事程序中的/lib/ts替换我自己的时候，就可以使用了，实在不知道怎么办了，问问大神们，我用的交叉编译器是arm-none-linux-gnueabi-gcc
------解决思路----------------------
tslib/etc/目录下的ts.conf文件有没有配置正确？是选择了module_raw input吗？
