USB Library Errors on All nRF52840 Dongle Projects

quendro_gmbh

Hi,

I have been using the nRF52840 Dongle for at least three months without any issues.
First, I implemented my project on the nRF52840-DK, then easily configured it for the nRF52840 Dongle, and it worked flawlessly.
However, starting from last week, I'm encountering the same USB library errors for all Dongle projects.
When I compile the same projects with the nRF52840-DK, they all work fine.
It seems that a general configuration or setting is no longer correct.
As an easy example, I share the Blinky project from the Nordic examples.
It works with the nRF52840-DK, but gives the same error with the nRF52840 Dongle.
When did I start getting this USB library errors?
I added ADC to the Dongle configuration, and now none of the projects work with the Dongle anymore.

Toolchain: SDK v2.6.1

Win10

Thanks
Saban

    Hi,

    I do not get error messages when building the blinky project you attached. Are you able to reproduce the issue in this project? Please try to delete the build directories before trying to rebuild.

    Best regards,
    Marte
