Error running NCS OpenThread CLI example

[GPereira]

Hello, when I run OpenThread CLI example in NCS 1.4.0, I get the following message on the serial port:

E: Failed to store setting 3, ret -22

I am using the nrf52840 DK

Hi GPereira,

    Did you get the WELLCOME_TEXT printout at first? or your only see this error from the serial port after reseting nrf52840 DK? I tried with putty and get the following printout:

This is what I get after flashing or resetting the board:

This doesn't happen with my nrf52833 DK

HI GPereira,

     Can you try to run "nrfjprog --eraseall", or "west flash --erase", or click this "Erase All" button on SES before reprogramming?

That cleared the error message, thank you!
