-> The zephyr sdk has bug in the [rp2350 pinctrl](https://github.com/zephyrproject-rtos/zephyr/blob/main/include/zephyr/dt-bindings/pinctrl/rpi-pico-rp2350-pinctrl-common.h) file. The `RP2_PINCTRL_GPIO_FUNC_UART_AUX` macro is defind, but `RP2_PINCTRL_GPIO_FUNC_UART_ALT` macro is used.

A [pull request](https://github.com/zephyrproject-rtos/zephyr/pull/111495) has been made to fix this.
 
 > [!NOTE]
 > While shell is over USB, the `adc scan_for` command uses uart. The UART uses spi1 pins, so the spi1 needs to be disabled and `extra_uart.overlay` needs to be used.
