1.编译带调试信息的内核，并将对应的zImage烧写到nandz中（bootloader在此必须已经正确的配置，确保传递参数的正确性）
2.目标板上电

3.启动OPENOCD并用telnet链接到OPENOCD然后说输入以下命令：
#halt
#bp 0x30008000 4 hw/*这是Bootloader加载zImage到内存的地址*/
#bp /*查看断点是否成功*/
#resume
3.minicom终端按下b键

4.回到telnet界面输入以下命令：
#rbp 0x30008000
#bp 0x300080d4 4 hw/*通过查看反汇编得知在这里开启MMU*/
#resume
5.这是minicom输出为

6.开启eclipse 配置arm-linuc-gdb初始化命令如下
target remote localhost:3333
monitor halt
monitor step
monitor rbp 0x300080d4
monitor arm7_9 sw_bkpts enable
hbreak start_kernel
continue
7.启动GDB然后可以看见在start_kernel处停止
