Doubts about programming

[Anderson Silva]

Hello.
I'm having problems to programme the nRF52832.
I'm just connecting the VCC (+3,3V), GND and SWDIO and SWDCLK.
Is it ncessary to connect any other devices like capacitors or reset pins in the circuit?
My problem is with programming process... I'm not beeing able to receive a "success" from the programming process.

I'm using the devkit nRF52-DK as programmer.
So I connecting the VDD (3V) pin (of P1 connector) to VTG (of P20 connector).
I connecting the GND pin (of P1 connector) to GND detect (of P20 connector).
And connecting VDD, GND (of P1 connector) to my board application. And connectiong SWDIO and SWDCLK (of connector P1) to my board application too.

This process occour very well with other boards that I bought few weeks ago (that are full assempbled but now, I'm tryng to do it in my application and it don't occour.
I'm not sure if is necessary to fill (solder) the PCB with all components to able the programming... because I believe that is necessary just the nRF and power supply.

Thank you.

Hi

It shouldn't be necessary to do anything different when your program an nRF52 the first time. Please make sure that your custom board is connected to the DK like in the picture below. I'd also like to see the schematics of your custom board so I can see that everything is connected correctly. If you don't want to share your schematic files publicly, please say so, and I will set this case to private mode so that only yourself and Nordic engineers will be able to see this case.

Best regards,

Simon

These jumpers are exacltly how I'm trying to programm the nRF52.
And bellow follows my circuit. It is very similar with reference design.
The marking code of the nRF that I'm using is "N52832 QFAA E1" (that I can't program). But I have other custom board with "N52832 QFAA E0" that I can program very well... Is there any diference related with this "E0" and "E1"?
