Dear all,
I was searching how to debug the fiasco kernel through JDB. The
following link gives a good approach how to it through minicom.
http://os.inf.tu-dresden.de/l4env/doc/html/dev-overview/ [1]
However, even if I see the messages on the screen, is it possible to
interact with JDB without having an exception? I looked at also the
"Fiasco Kernel Debugger Manual", however, I couldn't figure out how to
exactly interact with JDB. Until now I could only interact with JDB in
case of any exception occurrence.
you can interact with the debugger either by pressing ESC at any time
(requiring fiasco to be started with the -serial_esc option!).
If you want to invoke the debugger at any point in your code you can
also use the
enter_kdebug("Message");
function. It is defined in l4/sys/kdebug.h. Just include this header
and put enter_kdebug in your code when you wish to go into the debugger.
