[quote user="mosantos"]That said, why exactly is this the case? [/quote]

The SoC revision is different between the PDK and the DK.

[quote user="mosantos"]What happens if I build for the DK and then flash the firmware to a PDK board? [/quote]

Undefined behaviour.

Hi! Thanks for replying

"I would not expect the PDK to work with newer versions of the SDK."

That said, why exactly is this the case? If the schematics of the PDK and the DK are 99.9% identical, why shouldn't SDK v2.8.0 work with the PDK? Are there tricky constraints in the build system designed to prevent the newer SDK from running on PDK boards? Given that the .dts files for the PDK are nearly identical to those for the DK, what would prevent firmware built for the DK from running on the PDK if flashed manually?

Instead of using the command:

$ west build --build-dir builds/nrf54l15pdk -b nrf54l15pdk/nrf54l15/cpuapp --pristine

What happens if I build for the DK and then flash the firmware to a PDK board?

$ west build --build-dir builds/nrf54l15dk -b nrf54l15dk/nrf54l15/cpuapp --pristine

$ west flash -d build/ builds/nrf54l15dk --erase

Best regards

Hi,

The PDK is a Preview DK that is intended for use until the DK is released. I would not expect the PDK to work with newer versions of the SDK.
I recommend getting a DK.

PS: There is a silkscreen error on some versions of the DK where it says "PDK" on the silkscreen. Check the DK version to be sure. 0.8.1 and up should be DKs. Below is PDKs.
