Simple application with LORA enabled don't reach main function

[lfdominguez-servinfo]

Hi, here I have a custom made board that has a MDBT42Q module (nRF52832 based) and has connected a RFM95W LoRA module, I wrote a simple code:

void main()
{
    while (1) {
        printk("Hi!!!!");
        k_sleep(K_MSEC(1000));
    }
}

The only method to access to the board is using JTag with SWD protocol, I'm using a J-Link device. The thing is that when I debug the firmware, the control never get on main function, always is doing lora things (because I pause debugger and sometimes are on cpu_idle or lora functions).

I'm using this command to build west build -b nrf52dk_nrf52832 . and this overlay of the board to add the lora module.

&spi1 {
    status = "okay";
    
    lora: sx1276@0 {
        compatible = "semtech,sx1276";
        reg = <0>;
        label = "sx1276";

        reset-gpios = <&gpio0 4 (GPIO_PULL_UP | GPIO_ACTIVE_LOW)>;

        dio-gpios = <&gpio0 11 (GPIO_PULL_DOWN | GPIO_ACTIVE_HIGH)>,
            <&gpio0 12 (GPIO_PULL_DOWN | GPIO_ACTIVE_HIGH)>,
            <&gpio0 13 (GPIO_PULL_DOWN | GPIO_ACTIVE_HIGH)>;

        spi-max-frequency = <400000>;
        power-amplifier-output = "pa-boost";
    };
};

/ {
    aliases {
       lora0 = &lora;
  };
};

Find the solution, the problem was, that the builder of the custom board not connected the LORA modules SPI pins to the default ones, looked on schematic and changed the pinctrl in overlay to this:

// Custom PINS
&pinctrl {
	spi0_default: spi0_default {
		group1 {
			psels = <NRF_PSEL(SPIM_SCK, 0, 19)>,
				<NRF_PSEL(SPIM_MOSI, 0, 18)>,
				<NRF_PSEL(SPIM_MISO, 0, 14)>;
		};
	};

	spi0_sleep: spi0_sleep {
		group1 {
			psels = <NRF_PSEL(SPIM_SCK, 0, 19)>,
				<NRF_PSEL(SPIM_MOSI, 0, 18)>,
				<NRF_PSEL(SPIM_MISO, 0, 14)>;
			low-power-enable;
		};
	};
};

and then used this on spi0 config:

pinctrl-0 = <&spi0_default>;
pinctrl-1 = <&spi0_sleep>;
pinctrl-names = "default", "sleep";

And now is executed the main function, thanks.
