    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

    LIBS+=-lz
