Problem uploading to ADAFRUIT Feather 32u4 using Arduino 2.1

Alexander28

Hi all,

Long time fan of the technology, first time user of the forum.

Currently using a Windows 10 box, with Arduino 2.1 and the following board, from RS Components:

ADAFRUIT Feather 32u4 Development Board 2829

image

Long story short, I used to be able to upload to the board, and now it just hangs at the upload screen, then after 4-5 mins, gives me the below error.

I have used different USB Cables, USB ports and even computers, same issue. I am wondering if i am doing something silly...

This is what i am getting:

"Sketch uses 10934 bytes (38%) of program storage space. Maximum is 28672 bytes.

Global variables use 885 bytes of dynamic memory.

Connecting to programmer: .avrdude: butterfly_recv(): programmer is not responding

avrdude: butterfly_recv(): programmer is not responding"

Had a read of this too:

https://stackoverflow.com/questions/49283074/arduino-leonardo-avrdude-butterfly-recv-programmer-is-not-responding

have tried the 'reset button' before programming, getting the red pulsing light indicating it is resetting, and then tried the upload, still nothing...

Anyone know where i am going wrong?

Really appreciate any help, thank you all!

  • You mention you press Reset and then the red LED pulses; do you then also see the device appear in your Windows Device Manager? Does it come up in the Device Manager correctly, or does it come up in the Device Manager as an unknown device?

    I think that's a key step in your troubleshooting, because then you can make a decision if it could be a fault with the USB cables or the software drivers installation or a fault with the board itself. It is also a good idea to have another board (could be a cheaper one provided it is using the same ATmega chip) just for troubleshooting purposes.

    Comes up with the correct name in device manager and appears to install drivers properly etc.

    Have tried 4 boards which we have on site, all with same issue. can order more boards to try a fresh one?

    Thanks for the advice.

    Could be a PC issue. If it hangs for 4-5 minutes then the bootloader may time out during that time, which would explain why the output is "programmer is not responding" afterwards.

    I don't know if the bootloader times out after 10 seconds or so. You may need to complete the entire exercise within the 10 seconds after reset.

    It may be hanging for 4-5 minutes due to a permissions issue perhaps. I don't use Windows 10 any more so I can't comment much here. You really ought to have more than one board so you can narrow down problems quicker. 

    Also, make sure that no other hardware is connected, i.e. no additional wiring to your board when you're programming it, just in case there is something unusual going on there.

    I am presently testing with 4 boards and two computers. Nothing attached to the board, as i thought same as you, that might foul it.
    I might also have a look at firewall issues?
    But sounds from your guys responses that the key here is in the reset / bootloader.

    Thanks again, i will report back...
