Hi, everyone, I’ve been trying to upload code to the Artemis, with no success. This is what I’ve tried so far:
Using the Arduino IDE and the SVL bootloader, this is the error:
[10896] Failed to execute script artemis_svl
Traceback (most recent call last):
Artemis SVL Bootloader
File "artemis_svl.py", line 393, in <module>

el puerto seleccionado cleared startup blip

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:
Artemis SVL Bootloader
phase: setup
cleared startup blip
phase: bootload

/dev/ttyUSB0 is currently open. Please close any other terminal programs that may be using /dev/ttyUSB0 and try again.
If using bootloader_asb, the errors are:

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.
