Upload error on Mac

[wholder]

I have two Digisparks.  Both do this when I try to upload the "Start" sketch to either of them:



Binary sketch size: 756 bytes (of a 6,010 byte maximum)

I've tried connecting direct, and through a hub, but nothing seems to work.

Wayne - do you have anything plugged into the Digispark (shields/circuits) - if so remove them.


What type of mac?


Any chance you have a second machine, powered hub, or a mac monitor with USB ports on it - if so can you test with those?


Thanks for your patience!

I get the same issue when trying to upload directly on my MacBook's USB ports. Plugged into my iMac via a hub was fine. Will experiment with more combinations later and report back.

Also, I sometimes got this error with the MacBook direct method:

Assertion failed: (res >= 4), function micronucleus_connect, file library/micronucleus_lib.c, line 63.

No.  I didn't buy any shields and I have not connected any of the other pins.


What type of mac?

Happens on my MacPro connecting to any of the USB ports, or to the ports on my cinema display.  Also happens on my MacBook Air.

The only hub I have is on the cinema display I mentioned above and those also produce this error.


Thanks for your patience!

I had the same problem on my Mac.  I tried it on the keyboard and on a USB hub and had the problem in both places.  I resolved the problem by pressing lightly on the DigiSpark during the upload procedure, so that the pins made better contact with the USB hub.  Then it worked like a champ.  Hope that helps.
