Error occurred opening serial port. (NRF_ERROR_TIMEOUT)

[Javier]

Hi!,

I'm newbie with nRF52. I have a nRF51 Development Kit and a nRF52 Development Kit.

I have installed nRFconnect (for Ubuntu 64 bits) in Fedora 24 Workstation (64 bits)

nRFConnect starts well but when I select the serial port (/dev/ttyACM0 for nRF51 or /dev/ttyACM1 for nRF52) I received this error:

As I can solve it?

Best regards

Today this started happening to me too on Windows. My version of nRF Connect is v2.2.1.

I am using a PCA10040 board (nRF52 DK).

This is my logfile:
