Windows not recognizing 52Dk

[julian24]

I'm using the nRF52DK which uses the nRF52832. I was flashing a very simple program to the device using make, when it suddenly stopped working.

-I already tried different PCs and different USB cables.

-I also tried connecting nRF51422 and this device IS recognized properly.

-I can't go into Bootloader mode pressing the corresponding button, and the LD5 LED on the device doesn't turn on.

-I measured tension on the board and everything seems okay this way, 5V and VDD pins have the proper tension level.

Does anyone know what might be happeningto my device?

Best regards,

Julián

Hi Runar,

Hi Runar,

i think another important thing to mention is that i can connect and detect correctly my nrf51422. Do you know what might be happening? The thing that worries me the most is if my kit might be damaged, even though i measured a proper tension on 5v and vdd pins

Sounds to me the board might have been damaged somehow (eos/esd issue). You can try to update nRF Command line tools in case it's somehow software related, but I unfortunately think you will have to order a new one. What is printed on the label on the nRF52-DK?

Hi Kenneth,

what label is the one you are asking about? 

i'm thinking that i might have messed up the atmel interface mcu firmware, is that a possibility? How can i fix this? I read this post (for 52840, while i have a 52832) but the links are broken.
