I have one of the first 100 units from the kickstarter campaign and cannot connect to it. It shows up as a /dev/ttyACM0 and I can select this port in the Arduino IDE but compiling an uploading the blink example results in following message:
Sketch uses 11340 bytes (2%) of program storage space. Maximum is 524288 bytes.
No device found on ttyACM0
An error occurred while uploading the sketch
The output from dmesg when connecting the macchina is:
[ 1034.672578] usb 1-1: USB disconnect, device number 7
[ 1037.276947] usb 1-1: new high-speed USB device number 8 using ehci-pci
[ 1037.415675] usb 1-1: New USB device found, idVendor=03eb, idProduct=6124
[ 1037.415680] usb 1-1: New USB device strings: Mfr=0, Product=0, SerialNumber=0
[ 1037.418286] cdc_acm 1-1:1.0: ttyACM0: USB ACM device
and under Get Board Info following info is listed:
BN: Unknown board
SN: Upload any sketch to obtain it
I did try the “erase and reset” procedure pressing the erase button and then the reset button but this gives the same results.
Any ideas how to get this resolved and get the board programmed?
