No suitable devicetree overlay specified PCA10059

[Jim Ellyson]

I'm using nRF Connect fo Desktop SDK v2.1.1 with VS code.
I'm trying to compile the zephyr adc example for the nRF52840dongle.
Everything works fine with the adc example with a nRF52840dk build and a nRF52840 board,
but if I try to build for the nRF52840dongle, it fails to compile with the error:

\src\main.c:79:2: error: #error "No suitable devicetree overlay specified"
79 | #error "No suitable devicetree overlay specified"

Can someone point me in the right direction?

Thank you.

Hi,

The sample requires that an ADC channel is specified, which is done in overlay files. If you look in the boards directory of the sample you will find that there is no nrf52840dongle_nrf52840.overlay file, so you will have to make one yourself. You can look at the nrf52840dk_nrf52840.overlay to see what is needed there.

Best regards,

Marte

Greetings Marte,

Thank you! That was the right direction.

Note to fellow dimwits: delete old build configuration and generate new build configuration after creating overlay file, before trying to re-compile. 

Problem solved, case closed.
