Hi, everyone, I've been trying to upload code to the Artemis, with no success. This is what I've tried so far:
  • 2 Blackboard Artemis Nano and 1 Blackboard Artemis Uno
  • Tested in 3 computers with Ubuntu 18 and one computer with Windows 10
  • Versions of Arduino 1.8.9 and 1.8.10
  • Drivers for the CH340 have been updated; module ch34x loaded, and ch341 unloaded.
  • Several USB-C cables, some of them known to be working with SSD disks.
  • Board definitions for the Sparkfun boards installed and up to date
  • Permissions and groups are OK
Using the Arduino IDE and the SVL bootloader, this is the error:
Code: Select all
[10896] Failed to execute script artemis_svl

Traceback (most recent call last):

The last error lines mean "The selected port cleared startup blip does not exist or the board is not connected."

When using the Makefile to load the sketch the infamous port-is-currently-open error appears:

I've tested everything I found in forums and webs for days, and anything seems to work.
Also, I find strange that the result varies depending on the method. I'll keep investigating.
In anyone could help, I'd be really grateful :)

Cheers,
David.

Finally I decided to try with the Redboard model. Everything works fine from the beginning.
I understand the Blackboard are development boards and changes will appear in the final product but, as the Blackboard and Redboard share documentation and tutorials, I think the differences should be documented. It can be really frustrating spending lots of hours trying to make it work with no success.

Cheers,
David.

Hi, I finally bought the Redboard version, which works perfectly.
I'm in the process of returning the Blackboard ones.

Cheers,
David.
