Hello everyone,
I'm developing an application using the SX128x radio with the LoRaWAN Basic Modem.
The project runs successfully on a custom board based on the nRF5340 using nRF Connect SDK v2.9.0.
Now, I'm migrating to the nRF54L15, and I really need to use nRF Connect SDK v3.0.0.
However, when running the same code with SDK v3.0.0, no SPI activity is observed on the oscilloscope—it's completely silent.
I currently use SPI0. No LOG Erros from spi API or spi device was showed. The spi code:

Has anyone experienced a similar issue or can offer guidance on this behavior?
Thanks a lot in advance!
