Unable to upload anything to Blackboard Artemis, perhaps Library error?

SPARK-X

I am getting some major errors after recently purchasing a Blackboard Artemis and following the steps to install the boards. I am trying to run Blink but am unable and get this instead. I’ve tried reinstalling the sparkfun boards, reinstalling the Arduino IDE and restarting my computer but same error.

I think this might be because I’m on mac actually. It works on windows. I’m gonna leave this up incase anyone else has this problem

I have the same problem. I’m on a Mac as well. :frowning:

I can’t seem to get Blink to load on my Artemis Nano, on Mac. I turned on verbose error if anyone finds this useful - thanks!

Same.

I’m not super familiar with the program folder organization on Macs and I haven’t tried using the Artemis board yet, but when you reinstalled the Arduino IDE, did you delete the (temp) AppData folder for the program (usually hidden). I know in on Windows and Linux computers, that usually helps when reinstalling the Arduino IDE when I have ESP32/82666 issues. That might be a good place to start.

Otherwise, I believe this issue may have been [resolved with the latest core update.](https://learn.sparkfun.com/tutorials/artemis-development-with-arduino/discuss#comment-5d1a323933606d5d6e28ee33)

Hi everyone - thanks for the reports about operation on Mac/Linux - these are our weak points in testing.

The permissions error should be fixed in v1.0.2, however there is an additional bug in the bootloader, thanks to inconsistent timing of Serial port open/close on Windows vs *nix based systems using Pyserial. I’m working on a fix now that will come in v1.0.3… hopefully very soon
