Hi everyone,
I have an nRF52840 DK. So far, I have been programming the nRF DK using the UBS connector J2 and everything worked great.
Since yesterday, by following the exact same procedure, for some reason the nRF52840 DK is not recognized by the USB port.
(SW8 is set to ON ,SW6 is set to default, SW9 is set to VDD POWER)
When I attach my second nRF52840 DK it works great. So I cannot understand what is going on with the first DK.
When I measure the voltage at 3v and 5v pins of the board everything looks good but the LED of the debugger is always off.
Also the code that already exists in the nRF52840 does not function. I verify it through the test LEDS of the DK. When I change the SW6 position to nRF_ONLY and then immediately back to DEFAULT the nrF52840 begins to function properly but the debugger is still not recognized by my computer
The obvious reason is that it has something to do with the de bugger's microcontroller . But I don't know how to prove that a
different way so if you have any idea of what is going on and what what I am doing wrong please reply.
Thank you
