Has anyone successfully used the Sparkfun Digital Sandbox with the platform.io toolchain?
When I upload to my sandbox, the lights tx/rx lights blink and there is some initial communication, but then I get the repeated “programmer is not responding” error, and the program does not upload to the device.
My platform.io project ini includes:
[env:sparkfun_digitalsandbox]
platform = atmelavr
board = sparkfun_digitalsandbox
framework = arduino
#upload_port = /dev/cu.usbserial-A9048KU5
I get the same error with and without the upload_port config.
Any tips?
