SPI Slave example for NRF54L15 that functions (or at least compiles!)

[Steve Rathjen]

I've been trying to get SPI slave running on the NRF54L15-DK for over a week.  I am new to Connect SDK but have successfully completed this task with NRF52840-DK (and dongle) and SDK 17.0 and SES.  Took a lot less than a week!

None of the examples I've tried will even compile (VS in Linux and nRF Connect SDK 3.1.0).  Tried all the 'samples' in the SDK folders which won't even compile out-of-the-box.  None of the examples seem to use the same 'technique' to use SPI slave... which is correct??

Can someone point me to a WORKING SPI SLAVE example for the NRF54L15 and nRF Connect SDK (newest)?  Or at least documentation that describes the CORRECT steps for using the SPI as a slave?  I'm tired of shooting in the dark.

Thanks!

So no SPI_SLAVE example? I can' find either.

Did you manage to use SPI slave?

Thanks

Yes, I did get it working.  There are a few pitfalls to avoid, like SPI21 or SPI22 seems to not be supported... maybe only not as a slave, so switching to SPI00 fixed a lot of issues for me.  Also using NRFX SPIS, not Zephyr, worked for me.
