qemu-system-arm -M mini2440 -serial stdio -mtdblock nand.bin -usbdevicemouse 在nand.bin中可以不需要u-boot.bin，
在当前执行这条命令的文件夹下有u-boot.bin即可，一开始进入的u-boot是当前目录下的u-boot.bin
GDB
./local/bin/qemu-system-arm -M mini2440 -serial stdio -mtdblock nand.bin -usbdevice mouse -S -s
gdb-multiarch u-boot
target remote :1234
编译出现undefined reference to symbol 'timer_settime@@GLIBC_2.3.3'
修改Makefile.target，
搜索 LIBS+=-lz, 添加一行 LIBS+=-lrt
