.ds文件造成的卡死 [复制链接]

 .ds是debug的脚本文件,但是例程里面的很多.ds都有个问题
如这个:

1. # Reset and stop the system.
   
2. reset system
   
3. stop
   
4. wait 30s
   
5. 
   
6. # Disable semihosting.
   
7. set semihosting enabled false
   
8. 
   
9. #
   
10. # Load the SPL preloader into memory.
    
11. loadfile "$sdir/preloader_scrubbing/uboot-socfpga/spl/u-boot-spl" 0x0
    
12. 
    
13. # Delete any existing breakpoints.
    
14. delete
    
15. 
    
16. # Set a breakpoint in the SPL function spl_boot_device(). This function is
    
17. # called right before the SPL tries to load the next stage in the preloader.
    
18. tbreak spl_boot_device
    
19. 
    
20. # Set the PC to the entry point and go.
    
21. run
    
22. 
    
23. # Wait for the breakpoint.
    
24. wait
    
25. 
    
26. # Load the demo program.
    
27. loadfile "$sdir/hello.axf" 0x0
    
28. 
    
29. # Run the target and break at main().
    
30. start

看命令行发现,总是卡死在
# Wait for the breakpoint.
wait
如图:

这里面,,删掉这个wait就能正常调试了.
有的程序会卡死在这,有的不会,真是醉了,,,这个好像是等待preloader加载下一阶段boot的断点的,,,,搞不懂这样有啥意义,,
