GDB

@billyfish
Tried your new commit: just crashes in amigaos_deprecated_xfer_memory() once I set breakpoint and execute test binary :) There is the full log from serial:

(re)cloned billyfish gdb repo, did a full recompile and now at least works

But I didn't press Y/N it just "automagically "answered" Y::

Thanks guys, I still haven't managed to get the breakpoints working, grr! Roman, can you remember when we did we have breakpoints working? If we did, then that will give me a base to compare to.

The helloworld example doesn't crash for me but the breakpoints don't work. For example



Runs without crashing but any breakpoints just get ignored.

I've uploaded some updates which that to deal with the debug messages sent by our hook function. For instance,



will now get caught by gdb, though you can't inspect the variables, etc. yet. So that needs adding too. Hopefully the code from https://github.com/alfkil/Spotless/blo ... r/SimpleDebug/Symbols.cpp will give that to us.

If you look at lines 96-109 of amigaos-nat.c, there are two new flags to adjust which functions get used by our target



So still more to do but hopefully the breakpoints will work soon!

As far as I can tell, we never have a working breakpoint in our version, we only now reach the point when we start to make it works.

I downloaded now your latest commit at this moment, and rebuild it all from scratch, and tested it on x5000 firstly - still crashes.

Results from serial:



Results from the console:




Then tried it on pegasos2. There I didn't have a crash, but after I set breakpoint and hit "run", it then didn't stop on a breakpoint and didn't give me the ability to type things in the terminal (i.e. it didn't finish the executing now as well)

Results from the console:



As far as I can see when comparing serial logs from x5000 and pegasos2, x5000 do not like the "amigaos_xfer_memory()" function. It can be that it has an issue, just a crash didn't happen on other than x5000 machines by some luck (maybe that issue indirectly can have impact on non-working breakpoint code?)
