How to program custom board with nrf52811

[RafaelAguiar]

Hi guys

I ve made a custom board using the nrf52811 SoC,and now i want to program it for testing.

The thing is i am really lost on what to do, this is the first time tinkering with embedded systems.

I am planing to program the board with j link, basically i want to send my program via usb to j link and from j link to my board.

But i just dont know how to do it.

Any help will be much apreciated .

Hi,

If you're using a stand-alone J-link debugger then you have to connect the J-link to the SWD interface on your custom board. The SWD interface consists of SWDIO, SWDCLK, VCC and alternatively the RESET pin. These pins has to be routed out on your custom board. You also need to supply your customer board as the J-link debugger will not do this. After connecting the J-link interface, you can use either use an IDE such as SES or program your hex file with nRF Command Line Tools.

Hello

I am using a jlink debugger like you mentioned

I connected those pins like you said,except reset because im not using it.

Using SES i did the following : connected jlink,download the project

I wanted to test if the board emites some signal, and i tried do receive it on my phone, but i didnt receive anything.

Any ideas on why its not working? ( followed the reference design, one of the pcbs has a printed antenna and another has an antenna attached to sma connector,im sure the code is not the problem)

Thank you
