GDB debugging is debugging in general, GDB is Gnu DeBugger and exists in various forms.
The standard GDB is a commandline tool, but still very useful.
Then there are loads of front-ends like insight which is really good and userfriendly.
And yes, it works with DKA.
The FW you need is a slightly modified standard FW, it looks and smells exactly the same, the only difference is that i have added
the ability to handle exceptions because thats what makes debugging possible.
Some day mr.spiv will add those changes to his multi FW. (If you ask him politely he might even do it
One thing that might be a problem is that there must be a gdbserver application running, which communicates with the GP32 through the USB cable
and with GDB through TCP/IP.
I wrote that app for linux, and have been hoping that someone would port it to windows, but no one has yet.
I don't think that i'll ever do it myself since i don't have windows installed and i don't think anyone would use it anyway.
But if you are interrested, take a look at
