[avr-gcc-list] News on debugging Mega128?

[Wolfgang Wegner]

Hi list,

hopefully I did not simply overlook anything on the list...

Are there any news about debug information for >64k flash size with 
gcc?
Currently I have avr-gcc 3.4.3 from the latest official WinAVR 
installed, with which it is not possible to debug a program with more 
than 64k Code size. I am not sure if these restrictions are imposed 
by the debug info format (probably not) or the handling inside the 
compiler. I do not have much experience in embedded programming (I 
mean the linking part, which is quite different from what I am used 
to from the user-land part in unix), so I am not sure if I could help 
in changing this situation, but am willing to provide testing and 
more if somebody could tell me where to start.
Or is the restriction in AVRStudio, should I try to debug avarice to 
use gdb? (It has some problems with my JTAG-Ice mk2)

Or is there a newer code-tree of avr-gcc that would be worthwhile 
building from scratch? No problem to do so, but I read something that 
the AVR part of gcc-4.0 was still not as good as 3.4.x? Is that true?

Any hints from somebody who knows more about gcc from the inside are 
welcome!

Thank you,
Wolfgang
