nrf52840-DK to program E73-2G4M08S1C module

[GS2]

Hello, Can use nrf52840-DK to program E73-2G4M08S1C module with nrf52840 or I need J-Link Edu Mini for that ?

Hello, Can I use nrf52840-DK to program E73-2G4M08S1C module with nrf52840 or I need J-Link Edu Mini for that ? If yes - how to make connections?

Hi, Greg. I can't see a reason why you shouldn't be able to use the nRF52840 DK to do that.

The debug output section of the nRF52840 DK's PS describes how the custom board should be connected to the DK.

The description of the same subject in the nRF5340 DK's PS contains more figures, which may help understand what it should look like with the nRF52840 DK as well.

Best regards,
Mathias

Thank you Mathias,

Yes, I see outputs from DK:

3	SWD1_VTG	Voltage supply from external target that is used as an enable signal for activating SWD1
4	SWD1_SWDIO	Serial Wire Debug (SWD) data line
5	SWD1_SWDCLK	SWD clock line
6	SWD1_SWO	The Serial Wire Output (SWO) line is not used for programming and debugging over SWD
7	SWD1_RESET

but what inputs on module E73-2G4M08S1C -

I found only:

37 SWD SWDIO
39 SWC AC24 ???

Do you have a reference for connection - so I will not burn anything?

And which one I need - connectors P19 or P20 ?

That sounds right. From the module's datasheet:

From the aQFN73 package's pin assignment list:

That's what I linked you to earlier, with the additional figures in the nRF5340 DK's PS.

That is up to you and the connections of your custom board. The nRF5340 DK's PS has figures both for connecting through P19 and P20.

So, you do not know how to connect!

Can you ask somebody how knows?
