OK, but my question was more about the "gdb" side of things. The reason I work with the arduino micro is that the other people of the homebrew group are used to work with arduino (and a little bit of PIC), so I want to stick to something they work. Even, it turns out an atmega32 is powerfull enough to to AFSK demodulation (as long as you stick to 8 bit samples, but for AFSK that is good enough), actually a bit to my surprise I must say! But, I guess, from the "gdb" side of things, it should be simular: you enter commands in gdb and which get send to avarice or st-link. Or am I wrong? A "reset board" should be simular or any board, or not? My problem is learning how to use gdb better. According this video of david, it does seams to be possible to do some advanced things with gdb: http://www.youtube.com/watch?v=u4svoub6XcE > Both the Discovery board and the STLINK/V2 will allow you to connect > to a running application using gdb. Well, I have a discoveryboard and I get as far as to compile, run and remote-debug the "hello world" (blink_a_led) application on it.
