RE: BL654 nftBlinky example doesn't build with sysbuild

Hi Darren, Hi Andreas - I came across this case whilst investigating a related issue.

A fix for the BL654 USB has been pushed to mainline Zephyr, details as follows.

Happy to help!

I'm not quite sure what could be the rootcause of the error but it seems to be similar to issues which are caused by either

The folder still being present (pristine build is not as pristine as one would think. I recommend to instead always delete the build folder if you've made configurations)
The board is not being found and/or there are something missing in the board files that the sample depends upon

It's hard to say, but if you're able to keep going with the nRF52840dongle instead then I suggest we keep the BL module on the back burner for now

Kind regards,
Andreas

Thanks for looking into it Andreas.

The build log for Blinky is below. In the meantime, I figured out how to get my project, when built for nrf52840dongle, working on the BL654 USB dongle anyway (it was getting stuck in mcuboot due to a port pin). As such, I don't need to build for BL654 specifically any more and can just use the nrf52840dongle builds.

Yes, I found lesson 8 very useful as in introduction to sysbuild but it doesn't address this particular issue as far as I can see. I'd be interested to know why the build fails for BL654 but I can move forward anyway so no worries if you have better things to do !

Thanks,
Darren.

Hi,

Could you upload the full build log?

In addition, have you seen https://academy.nordicsemi.com/courses/nrf-connect-sdk-intermediate/lessons/lesson-8-sysbuild/topic/sysbuild-explained/?

Kind regards,
Andreas
