How to program thingy 52 using NRF52 DK

[Manel]

Hi,

I cannot find the pinout for the P9 connector in the Thingy (programming). My idea was to use the NRF52 DK to program it as this video suggests:

Any pointers appreciated!

Hi Manel,

You can find the pinout of P9 connector in the Thingy:52 Hardware files. The simplest way of connecting the Thingy to the nRF52 DK would be using a 10-pin 2x5 1.27 mm pitch cable, like this one.

Best regards,

Jørgen

Hi Manel,

P9 connector is clearly visible on Thingy HW description (Figure 2 here). When it comes to debugging/flashing there are many examples here as Q&As, Blog posts and Tutorials. The simplest options should be using any nRF5x DK board with 10-pin JTAG ribbon cable and connect P20 or P19 (Debug out) ports to Thingy P9. Then use built-in SEGGER J-Link debugger to connect with your IDE (e.g. GDB to Eclipse, Keil, IAR...) or just use any flashing tool to erase and flash nRF52 chip on Thingy with your HEX file (e.g. nrfjrpog from NRFTOOLS bundle, nRFgo Studio if you like Windows GUI tools, SEGGER J-Flash lite if you want to go with some 3rd party... there are like hundred of other options as well).

Cheers Jan

Hi Jørgen, found it, thanks! I wonder why it is not included in the Thingy 52 pdf as all other connectors are. I will try the four cable connection as in the video while I wait for the correct cable to be delivered. Thanks a lot!

Hi Jan, thanks for the information! I was suspecting there is an existing cable as both connectors have the same pins and are named the same, but wanted to try the four cable connection while I get the cable. Thanks!

What type/size of cable should I use for the Thingy? ...I have a 10-pin JTAG ribbon cable but it is big
