Hi, Michael: Thanks a lot. I attached the script. Hope I am doing it right. And I think I need to explain what happened in my debug. I set up two breakpoint, both of them are function call, first is PSPRINTF which is kind of like printf. And second is a function named PersistentMemoryDump. The first one works ok, but second one not. The different between two is that, printf have somd arguments need to pass, so there are some other assembling code before 'bl', so the address for breakpoint is not a 'bl' command; but second one is different, the breakpoint hit the 'bl' instruction. After stopped, the arm will restart. I checked assembling code and found the first asm code is 'STMFD'. It looks like the stub code replaces the STMFD, and the real lr got lost. (I am totally lost my mind.) And I got another question about print. There are lots of printfs in my code; but I only know "set debug serial 1" to print them out, and you can see in my script, it looks ugly. I tried some print set up to make the prinf command can print out pretty result in GDB, but I failed. Is there having that kind of setup in GDB? And thanks.

Please use the 'script' command to make a 'typescript' file. Like this: shell% script Script started, file is typescript shell% gdb myprogram (gdb) ... (gdb) exit shell% exit Script finished Then write another e-mail and include the typescript at the end of the mail. Michael C
