feather 32u4 Programmer not responding

[docingo]

Hi,

after I uploaded the last sketch to my feather board with a gps featherwing connected, I am not able to upload any sketches anymore :/

The verbose out stops at "Programmer not responding". Here is the output of the console:

----------------------
Sketch uses 12598 bytes (43%) of program storage space. Maximum is 28672 bytes.
Global variables use 2098 bytes of dynamic memory.

-------------------

I have a second board which works fine - no problems in uploading.
I also tried to upload other very simple things to the board not responding.

Can anybody help me out?

Thanks and best regards
Ingo

sorry for the unconvenience, I just found this post which helped me:viewtopic.php?f=24&t=168680

It is about resetting the board while the ports are listed in the IDE.

A bit difficult to hit the right button in time, but after the seventh try, I was successful.

Sorry again.
