Re: [avr-gcc-list] inline debugging stk200/stk500 and gdb 5.x

[Theodore Roth]

Hi,

Avr-mon needs to be updated to use the gdb remote serial protocol. The
protocol is implemented in simulavr in the gdb.c file. I've looked at
bringing avr-mon up-to-date with the current gdb and it looks straight
forward but slightly involved since I didn't do a great job of
separating gdb.c from simulavr internals.

If enough people are loud enough with requests, I will tackle it. ;-) I
will also help anyone who wishes to work on it.

Also of note, the upcoming gdb-5.2.1 release will have avr support without
needing a patch.

Avarice-1.5 needs a patch to work with latest gdb. The patch is on the
simulavr website. Scott Finneran has the patch, but hasn't updated avarice
in a while.

Simulavr-0.1.0 works with latest gdb.

:) Hi again,
:)
:) I found an old mail from December 2001 where Thedore Roth have already
:) discussed this item, but thats the last thing i found :-(
:)
:) To modify the sources to use uart is really no problem, this is only
:) patching some lines. This should be optional, so we can use parallel
:) port dongle or rs232. OK, now we need some help in modifieing the
:) sources to work with actual gdb's. The last patch for gdb is included
:) in main tree of gdb now? No longer need to patch or? Can Theadore give
:) some instructions or spend some time :-))))) in doing this project.
:) Sorry, but I really know nothing about underlaying protocols in gdb.
:)
:) Thanks a lot
:)     Klaus
