Hi RTers,
The debuggers available (zentropix/fsmlabs) are both based on gdbstubs
(maintained by David Grothe, ftp.gcom.com). To work with modules,
gdbstubs was enhanced by zentropix over a year ago to reply to the
qOffsets with the correct sections for the modules (text, data and
bss), the fsmlabs version works the same way, but can be used locally
via fifos rather than a serial connection. The problem with this
approach is that the offset is applied globally, and so only one module
can be correctly debugged at a time. At the time I originally made the
changes, I looked into the add-symbol-file command to allow multiple
modules to be debugged, but this wasn't working. Since then, a lot of
progress has been made by the gdb and gdbstubs team, and this feature
seems to mostly work. We are currently working on using this method to
allow multiple modules to be concurrently debugged. There are some
problems to be resolved (it doesn't seem to work on some versions of
gdb), but it looks promising.
Until this approach is used, I think that you will be limited to
debugging a single module at a time.
Regards, Stuart
