问 用光盘自带的例程，用交叉环境编译了之后在板子上跑的时候提示如下错误，
./loadgpio
insmod: not an ELF file
insmod: Could not load the module: Success
pid 43: failed 256
Execution Finished, Exiting
pid 38: failed 256

之后./key
kmod: failed to exec /sbin/modprobe -s -k char-major-126, errno = 2
CAN't open P0!
pid 44: failed 65280

就是设备没有驱动起来，怎么解决啊
PS：其他相关设备驱动的都有问题啊 答 1: reGPIO驱动没有加载成功，请重新编译loadgpio，
然后再./loadgpio
之后./key
