[AVaRICE-user] debugWire : debug slow...

[Rémi P. <mr....@la...>]

Hi all,

I'm debugging ATmega328p with avarice + avr-gdb + avrdragon using debugWire.
My binary is compiled with following options : -g2 -gstabs -O0 
-ffunction-sections -fdata-sections -std=gnu99
All is right... But debugging is very slow, stepping is awfully slow 
(~5s), and breaking is also quite slow (~2s).
Moreover if have often to reflash code, it seems flash get corrupted 
when debug sessions does not finish cleanly.

I've written topic about this issue here 
http://www.avrfreaks.net/forum/avrdragon-debugwire-atmega328p-nice-unusable
But for now, I haven't found any people working with a usable debugging 
environment with debugWire and avr-gdb... Suggestions are about changing 
toolchain and debugging tools in order to use some proprietary solutions...

Have you got some suggestions in order to debug efficiently?

Regards.
