My kid needs this for a school project so I'm kind of desperate over here.
I have a brand new mBot with mCore board. I tried two versions of mBlock software, both 3.3.1 and 3.4.1.
I ran them on MAC OS X El Capitan (10.11.6) and on MAC OS X Yosemite (10.10.5).
On both computers I got the same outcome - UPLOAD FAILED.
mBlock software is opened in Arduino mode so it is visible that the last information during the failed upload was PROGRAMMER IS NOT RESPONDING.
What can I do to upload my kids' program into the mBot?
Thank you for your kindness.
