老了，紀錄在這邊一下
1. Insert Module
#cd mtp_ios
#make --> mtp_io.ko
#insmod mtp_io.ko
#cat /proc/devices | grep mtp_io (Driver register name) --> get module major number 121
#mknod /dev/mtp_io0 (Ap open device name) 121 0
2. Compile AP
#cd mtp_api
#make --> mtp_api.so
#cp mtp_api.so /usr/lib/.
#cd test_mtp
#make
#./test_mtp
done!!
