Itsybitsy NRF52480 Wont respond

by oboucher on Thu Jan 21, 2021 7:48 pm

Hello, I recently bought a nRF52480 based itsybitsy, and I cannot get it to function with the arduino IDE, when I try to upload code I am unable to select the port it is connected to. I have tried to put it into dfu mode by grounding the R pin when plugging it in and it did not work. I have a Feather nRF52382 that i am able to program, so I believe that my tools are set up correctly. I do not have access to a segger j-link to ref-lash the bootloader, and was wondering if there was another way to do it.

If it helps I am using a Mac running macOS 11.1, and my Arduino IDE is version 1.8.13.

Did you double-press reset to put it into bootloader mode?

You might need to do that at times. Not just that board either.

Have fun!
