I've been trying to use SPI instead of QSPI to connect the nrf7002 to de nrf5340 on the nrf7002dk. I used the wifi shell example from nordic. I used an overlay file to reassign the nrf7002 module to de SPI pins, and the example is building correctly. I have an issue at running time. This is whats appears at the terminal:

I suspect that there are errors in the configuration, but i couldn't find any information about this.
