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 ?

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 ?

Thank you mathiaso,

Can you please verify and edit the TABLE I made based on above information:

E73-2G4M08S1C		P19		P20
19	VDD	1	EXT_VTG Voltage supply	3	SH_VTG Voltage supply from
21,24	GND	3,5	GND Ground	???	GND Ground
26	RST	10	EXT_RESET	7	SH_RESET Reset line
39	SWC AC24	4	EXT_SWDCLK SWD clock line	5	SH_SWDCLK SWD clock line
37	SWD SWDIO	2	EXT_SWDIO SWD data line	4	SH_SWDIO SWD data line

What PIN will go for P20 GRD ?
Do I need:
P19.9 EXT_GND_DETECT Ground detect
P20.1 VDD_nRF nRF52840 SoC power domain
P20.2 VDD_nRF’ Main nRF52840 DK power domain
P20.8 SH_GND_DETECT Ground detect

Thanks.

Also:

1. Is his secure way for production programming?

 2. What should I do to make the code locked - not readable?

Thanks again

Hello, mathiaso

No response - Are you OK ?
