If the Thingy:52 is supplied externally then SB47 should not be shorted. Programming the Thingy:52 is done exactly the same as you would program any other nRF52 custom board. You use the onboard debugger on the nRF52840 DK and connect it to the Thingy via the 10 pin connector. That's the setup.

I am telling both power and non power cases not working for me.

Just tell me the setup to program/debug thingy 52 using nRF52840 DK.

IF you still have the battery connected to the Thingy:52, why did you short SB47?

If it is inconvenient to have a separate power supply on the external board, the nRF52840 DK can supply power through the Debug out connector (P19). To enable this, short solder bridge SB47. Note that as long as SB47 is shorted, it is not possible to program the onboard nRF52840 SoC even if the external board is unplugged.

Also, what voltage do you measure on VDD on the DK?

-->3V

SW9 is in VDD.

Have you checked that the the board is properly supplied from the nRF?

-->Here it is thingy 52 is battery powered. If I remove battery thingy is not powered from Jlink.

Hi,

Please answer this:

[quote user="Jared"]Have you checked that the the board is properly supplied from the nRF? How is SW9 configured on the DK? If it's in either Li-po or USB, have you configured the REG0 register to anything other then the default value? [/quote]

Also, what voltage do you measure on VDD on the DK?

Firstly I am trying to work it out with Nordic Thingy 52 to fix out PCA10056 configurations. One more point to mention is on PCA10056 I have shorted SB47.

Hi,

What voltage does the DUT demand? Have you checked that the the board is properly supplied from the nRF? How is SW9 configured on the DK? If it's in either Li-po or USB, have you configured the REG0 register to anything other then the default value?

Just something that is good to check ;) : I sometimes have the issue that I don't press the J-tag connector firmly enough so that the pins actually have contact to the pads.
