nRF5340 DK LED5 is bright SW9 is on VDD mode and the PC doesn't Detect the board not working

[Dilghas]

Hello,

I have recently received the nrf5340 development kit as part of the Hackster contest.

I followed the webinar and to get started 

1. Connected board via micro USB and turned Power switch to ON position.

2. the LED5 besides the MCU is on.

3. SW6 is in a DEFAULT position. SW9 is VDD power source position. SW10 is in the OFF position. 

4 Downloaded nRF connect for desktop and nRF programmer tool, but the select device stays grey with no device.

How do solve this error.

Measure VDD with GND - 1.73v

Could you try using another usb cable and port? And could you measure the voltage at "VDD nrf" too?

Best regards,

Håkon

Tried with 3 different USB cables and no result.
"VDD nrf" measured as 1.50v

[Elfving]

That's a bit low.

Could you turn it off and on using the power switch after its plugged in, and then make sure that the switch is pulled far towards the on position? The 5340dk can have some issues with its switches. 

And could you take a photo of your board?

Best regards,

Håkon

Tried switching several times.

Thanks!

Hmm there doesn't seem to be anything immediately wrong on the picture here.

Then it might unfortunately be a defect board, I suggest you get a new one. I'd love to send you one, but as you got this through the contest, that is already over, I am afraid I can't. 

Let me know if there is anything else though!

Best regards,

Håkon

Hey,
I raised the ticket before the contest time. which I couldn't,t complete also. please try to send me a new one.

[Elfving]

Its more about the fact that the board was acquired for free through the contest, but maybe there could've been some leeway if the ticket was raised five months ago.

Sorry.

Best regards,

Håkon
