Shall I use bdi telnet interface to set hardware break point or use gdb, or they are the same?
I think you can only set/change the mode using BDI, but am not a GDB expert.
I set break point mode into "HARD", then using gdb set break point, it never stops; if I use bdi interface to set, I saw following message when continue in gdb:
(gdb) c Continuing. Warning: Cannot insert breakpoint -31. Error accessing memory address 0xfff00100: Unknown error 4294967295.
Does your BDI session mention at this point that there are no available breakpoints? Before setting a breakpoint in GDB, type "del". This will clear any existing breakpoints. The equivalent command in BDI land is "ci"
I think we should be able to use software break point in RAM image, right? I really appreciate if you could give a hand on this issue. I need it urgently to debug further issues.
You can use either type in RAM, but you'll find soft ones to be much more convenient. You obviously have bigger issues to work through first.
Have you contacted Abatron (or your Abatron representative) for help? They're usually extremely helpful.
