Debugging an AVR under Linux using the JTAG ICE mkII and gdb.

Demonstrates in-system-debugging of an ATmega128 with a simple example program (a running light). Notice that this is not a simulation, it's the real thing. The used tools are: The JTAG ICE mkII (connected via USB), avarice and avr-gdb. The GUI frontend to gdb seen on the video is ddd.

This would have been so useful to me a while back. Haven't done any AVRing since then. This should help you out a bunch

Yes, I'm sure it'll become quite handy. Actually debugging AVRs is quite cool ;)

nice vid! I really want a jtag ice mk2, but its so expensive.

[linuxgeek81]

Odin :D How's the art? I hope you do well?

Yes it's expensive but I got it rather inexpensive on the second hand market ;)

A very interesting room/workshop

You mean my living room? *jokingly ;)

nice video, where did you get that JTAG ICE MKII? and how much?

[mrCbeems]

You didn't get this from ebay?

i'd like to know more about the details on the jatgice mkii + avarice setup....

currently i'm struggling with avarice to talk with the OnChip Debug feature. how can i get in touch with you

Nice video! Thanks! Is it possible to set port pins / registers (e.g. PORTB, DDRB, etc...) using the debugger (so you could set an LED on directly rather than setting a variable that is then written to the port?

Hi..

I think you don't need a 16-bit int..

You can change your if to:

if((status <<= 1) == 0))

{ status=1;

}

because when status is 0xff and you shift it, it will become 0x00

great video, thanks for sharing!!!
