How to use PCA10056 DK P19 debug out to program external board?

[Sridhar Jonnavittula]

Hi,

What is the procedure to use PCA10056 DK Debug OUT P19 connector to program external board for eg Nordic Thingy 52?

I have shorted SB47 on PCA10056 DK but it is failed to detect idcode.

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 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.
