Unable to upload code to Zumo32U4

Hi,

I have been unable to upload code to my Zumo32U4 in windows 10 which has been working fine previously. I have tried both uploading before bootloader method, bootloader before uploading method and erasing the program with AVRDUDE. The Zumo32U4 is able to enter bootloader with the yellow light fading in and out and both the Zumo32U4 port and bootloader port show up in the device manager. Below is the verbose output in arduino for uploading. My zumo32u4 is connected to COM6 but for some reason Arduino forces a reset on port COM6 and then tries to upload to COM7 as seen below.

Thanks

Sketch uses 7454 bytes (25%) of program storage space. Maximum is 28672 bytes.
Global variables use 325 bytes (12%) of dynamic memory, leaving 2235 bytes for local variables. Maximum is 2560 bytes.
Forcing reset using 1200bps open/close on port COM6
PORTS {COM4, COM5, COM6, COM10, COM11, } / {COM4, COM5, COM10, COM11, } => {}
PORTS {COM4, COM5, COM10, COM11, } / {COM4, COM5, COM7, COM10, COM11, } => {COM7, }
Found upload port: COM7

avrdude done. Thank you.

the selected serial port
does not exist or your board is not connected

Update:
I have fixed the problem! I had recently mounted a pan tilt kit onto the zumo32u4 and realized that the mount was holding down buttonA and for some reason that was messing with the upload.

Hello.

I am glad to hear you were able to figure out the problem; thanks for letting us know.
