That is good to know. Thank you for the hint.

Cheers,

Sebastian

[quote user="Sebastian Stein"]I am looking forward to read the new sections as soon as they are ready. I am especially interested in the last point:[/quote]

In the meanwhile you could look at some other custom boards, based on the nRFf9160 and without the nRF52840. E.g. the Circuit Dojo Feather Board: zephyr/boards/arm/circuitdojo_feather_nrf9160.

Hi Simon,

thank you very much for your help. This is exactly what I was looking for.

I am looking forward to read the new sections as soon as they are ready. I am especially interested in the last point:

Show what should be removed.

Thanks again,

[quote user=""]Furthermore it would be great if you could tell me which parts of the documentation my colleague has to read to start with the hardware layout. Will the nRF9160 Hardware Design Guidelines be sufficient?[/quote]

- You may also look at the design for the nRF9160DK and the Thingy:91

Check out the NCS tutorial and section 2. Using a custom board with NCS. Jump straight to 2.2 Walkthrough to get to the practical part.

Check out the Board Porting Guide as well. You will find that in the Zephyr documentation, which you can get to in the following manner:

By the way, the 2.2 Walkthrough only shows how to create a new custom board folder, that you can use as a base for your specific board. It does not show how to add additional functionality to your board. I will add a new section to the tutorial soon, that go through some different scenarios. Something like this:

If your board only has one button, connected to GPIO 30
- Then you have to remove the other button instances, and change the GPIO of button1 to 30 (instead of 8)
If you have an adxl362 device on you board, connected to some specific GPIOs
- Then you could look at the board folder for the Thingy:91 to see how to add it to the board folder. Change the SPI instance if you want to use another, and select the pins according to how the adxl362 is connected.
- Then you can build the adxl362 sample with your custom board name and it should work out of the box
- (Be aware that this can also get added to an overlay file, but if the sensor is part of the custom board, the proper way is to add it to the dts board files)
If you don't have an nrf52840 on your custom board
- Show what should be removed. E.g. interface_to_nrf52840, nrf52840_reset++

I will get back to you tomorrow about this

Best regards,

Simon
