I'm trying to run Wi-Fi scanning or AP/STA mode examples on the NUCLEO-U575ZI-Q board with the nRF7002EK shield, but I keep getting an "RDSR2 register failed" error. I've tried with zephyr version also, but so far, I haven't found a solution. Interestingly, I tested the same shield with the STM32H747I Discovery board, and everything works perfectly — examples like the shell, AP/STA mode, and scan run without issues. However, on the NUCLEO board:
- The shell example fails.
The Wi-Fi interface shows as down.When I try to bring the interface up, I get the following error:
uart:~$ net iface up 1
Cannot take interface 1 up (-120)
If anyone has managed to get this setup working or has suggestions. Thanks![00:00:00.487,884] <err> wifi_nrf_bus: Error: RDSR2 failed
