Could you let me now your board name and version ?&nbsp;</p> <p><br />Do you have any other DK to test ? I would suggest to get hold of a nRF52 DK. The nRF51 DK is almost 10 year old.&nbsp;<br />On Linux and OSX you may need to disable Mass Storage Device as suggested in the log. But you mentioned that you had the issue on Windows 10 machine as well.&nbsp;<br />Could you capture the log on Windows machine ?&nbsp;</p><div style="clear:both;"></div>
