Re: BDI2000 breakpoints in dynamically loaded modules

["John W. Linville" <linville@lvl7.com>]

Just a guess...when you do the "add-symbol-file", do you specify the
address for the .text (and possibly other) section(s)?  If you don't,
I'm not sure what it will default to be, but it will almost certainly be
wrong.

When you do the insmod, use the -m parameter and redirect the output to
the file.  Near the top of that file it will tell you where the .text
section starts.

Good luck!
