Programming nRF52 SoCs with nRF5340 DK

[Shaun Brentnall]

Hi, I want to eventually be able to programme a custom built chip with an nRF52833 SoC on board, but first I thought I would try with a nordic Thingy:52. 

My setup is as follows:

Computer (Windows with nRF connect v3.11.0) <---> nRF5340 DK <---JTag---> Nordic Thingy:52

I can programme the nRF5340 DK via the nRF connect visual studio IDE, but I am not sure how to be able to connect to the nordic thingy_52 in order to be able to programme that device directly. On the 'connected devices' section in visual studio I cannot see the nordic thingy:52 appear, only the nRF5340 DK appears. 

Do I need to do something else in order to connect to the thingy to programme it? Or is the JTag physical connection sufficient?

Thank you for your help!

Can you also issue nrfjprog -v ?

When the nRF5340DK isn't connected to the Thingy:52, it does show up as a DK. 

And when it's connect by Jtag, it just say Jtag with unknown in the field to the right. 

And for the two commands in cmd, they are here. Only the nRF52340 identity number shows up as a connected device. And I can programme DK via nrfjprog, but not the Thingy:52.

Can you please provide an image of your setup?

Can there be an issue with you JTAG cable?

Hi Øyvind,

here is the setup of the hardware I'm using

I've tried a second thingy:52 and a few different JTAG connectors. The same errors as before appear. 

Could it be a problem that the Jlink versions are different?

Could you please disconnect the nRF USB and set nRF Power Source to VDD?
