I am using ATmel Studio ASF example to test program Due. I do not want to use VisualMicro wrapper for Arduino IDE.
The (only ONE) example compiles, won't download to Due port and then I get a cryptic error message about missing "connected tool".
Apparently the ASF examples require either hardware of software debugging "tool". The documentation really does not explain what this "tool" is nor how to add it to the Studio. There is an empty pull down box titled "Selected debugger / programmer" under Tool tab.
So far I am unable to post this to ATmel ARM forum, but I got some answers from ATmel AVR forum which I appreciate.
I also found old (2012 ) and now apparently abandoned site which shows running the same example without need for this mysterious "tool".
I am sure I am also missing the programming port assignment for ASF, but got one working for VisualMicro.
I would like to hear from someone who "been there done that". Cheers Vaclav
