All,

 

Question. Is it possible to use the mEDBG facility in the X-plain 328p(b) to debug via debug-wire an external AVR328p circuit on a bread board?

 

Thanks,

 

Randy

I am sure that you can just send the signals off to an external chip. i.e. just cut the XMINI lines to the onboard AVR.

It seems a pointless exercise. The XMINI can take standard Arduino shields. You are better off doing your prototyping with Arduino add-ons.
The onboard EDBG is incredibly slow. If you have a lot of development to do, buy an ATMEL-ICE.

David,

 

Yes I quite see your point, I am seeing the mEDBG being very slow to program, and the back channel UART only goes to 38,400 baud for me.

 

However, if you are content to just observe/debug some static running code, and don't have to do a lot or re-compiles, then it is well worth the effort.

 

Thanks so much for the consideration of your reply,

 

Rando
