Cannot upload to Feather 32u4

by ianmackinnon on Tue Mar 20, 2018 7:50 am

I have just received a Feather 32u4 but I have been unable to upload anything to it.

I have Arduino IDE 1.8.5 running on Linux. I have installed and updated the Adafruit board URL. I have Adafruit Feather 32u4 selected as the board type. The board appears on /dev/ttyACM0 and board info reports:

BN: Adafruit Feather 32u4
VID: 239A
PID: 800C
SN: (null)

I have tried the following:

Plug the board in and upload. Results in the error:

Code: Select all | TOGGLE FULL SIZE
avrdude: Device signature = 0x3f0d0d
avrdude: Expected signature for ATmega32U4 is 1E 95 87
         Double check chip, or use -F to override this check.

avrdude done.  Thank you.

Wrong microcontroller found.  Did you select the right board from the Tools > Board menu?



Press reset and upload. Results in the error:

Code: Select all | TOGGLE FULL SIZE
avrdude: butterfly_recv(): programmer is not responding



Upload and press reset. Results in the error:

Code: Select all | TOGGLE FULL SIZE
#avrdude: error: programmer did not respond to command: set addr



Double press reset and upload. Results in the error:

Code: Select all | TOGGLE FULL SIZE
Port name - /dev/ttyACM0; Method name - openPort(); Exception type - Port busy.



Can you please tell me what I have to do to upload a program to this board?

Many thanks.

I have Arduino IDE 1.8.5 running on Linux.

Did you add the udev rules?

I have installed and updated the Adafruit board URL.

In addition to adding the URL, did you also install the board support packages?

I have installed the udev rules and now uploading is working perfectly.

Thanks for the quick response.
