看样子是在执行gel中
  1. //*******************************************************************
  2. //Watchdog Timer registers
  3. //*******************************************************************
  4. #define    WDT1_BASE_ADDR                                        (0x44E35000)
  5. #define    WDT1_WSPR                                             (WDT1_BASE_ADDR + 0x48)

  6. //Watchdog is disabled to eliminate warm resets during debug
  7. Disable_Watchdog()
  8. {
  9.     WR_MEM_32(WDT1_WSPR,0x0000AAAA);
  10.     WR_MEM_32(WDT1_WSPR,0x00005555);
  11. }
复制代码

这一段出现的问题,非常奇怪

不懈努力后,解决了.
具体原因不明,
解决方法:上电时,确保不要进入linux即可(插入空tf卡,或者停在uboot内),然后进行调试即可
