使用xds100调试beaglebone [复制链接]

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. 
   
7. //Watchdog is disabled to eliminate warm resets during debug
   
8. Disable_Watchdog()
   
9. {
   
10.     WR_MEM_32(WDT1_WSPR,0x0000AAAA);
    
11.     WR_MEM_32(WDT1_WSPR,0x00005555);
    
12. }

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
