nRF9151 CONFIG_UART_ASYNC_API

[abdukhair]

Hi!

I am using nRF9151-DK, enabling UART1 and using CONFIG_UART_ASYNC_API.

The build is successful, but the problem every time i connect a flashed kit with this binaries into nrf Programmer software.

I get notification of "Application core is protected".

I have isolated all the included configurations and found out that CONFIG_UART_ASYNC_API is causing this.

Am i missing some configuration? How to overcome this issue?

UART-related config:

# Enable UART1 Async
CONFIG_SERIAL=y
CONFIG_UART_ASYNC_API=y
CONFIG_UART_1_ASYNC=y
CONFIG_UART_1_INTERRUPT_DRIVEN=n

Devicetree:

&uart1 {
    status = "okay";
    current-speed = <115200>;
    pinctrl-0 = <&uart1_default>;
    pinctrl-1 = <&uart1_sleep>;
    pinctrl-names = "default", "sleep";
};

Best regards,

Abdu

Hello,

Are you enabling mcuboot in your application, and what build configuration are you using? Are you building it for the _ns variant? If you are using mcuboot, you probably need to enable this in the mcuboot.conf as well. Can you share your project with a minimal configuration so I can run it here and reproduce the issue?

Kind Regards,

Abhijith

Hello, 

I am not enabling mcuboot in my application.

In order to replicate the issue with minimal configuration, i have:

• Used hello_dect sample
• Created within the project folder boards/nrf9151dk_nrf9151_ns.overlay

#include <zephyr/dt-bindings/gpio/gpio.h>

&uart1 {
    status = "okay";
    current-speed = <115200>;
    pinctrl-0 = <&uart1_default>;
    pinctrl-1 = <&uart1_sleep>;
    pinctrl-names = "default", "sleep";
};

/ {
    model = "Nordic nRF9151 DK NRF9151";
	compatible = "nordic,nrf9151-dk-nrf9151";

    digital_pins {
		compatible = "gpio-leds";
		digital_pin10: digital_pin10 {
			gpios = <&gpio0 10 GPIO_ACTIVE_HIGH>;
			label = "Digital Output PO.10 D10";
		};
		digital_pin11: digital_pin11 {
			gpios = <&gpio0 11 GPIO_ACTIVE_HIGH>;
			label = "Digital Output PO.11 D11";
		};
		digital_pin12: digital_pin12 {
			gpios = <&gpio0 12 GPIO_ACTIVE_HIGH>;
			label = "Digital Output PO.12 D12";
		};
		digital_pin13: digital_pin13 {
			gpios = <&gpio0 13 GPIO_ACTIVE_HIGH>;
			label = "Digital Output PO.13 D13";
		};
	};

    /* These aliases are provided for compatibility with samples */
	aliases {
		dpin10 = &digital_pin10;
		dpin11 = &digital_pin11;
		dpin12 = &digital_pin12;
		dpin13 = &digital_pin13;
	};
};

• Added these extra configs to prj.conf

CONFIG_NRF_MODEM_LIB=y

CONFIG_MODEM_ANTENNA=n

CONFIG_NRF_MODEM_LINK_BINARY_DECT_PHY=y
CONFIG_HWINFO=y

# Logs config
CONFIG_LOG=y
CONFIG_FPU=y
CONFIG_LOG_DEFAULT_LEVEL=3

# Transmission forver
CONFIG_TX_TRANSMISSIONS=0

# Data Rate Config
CONFIG_MCS=0
CONFIG_RX_PERIOD_S=100

# Generate random numbers
CONFIG_ENTROPY_GENERATOR=y

# Enable UART1 Async
CONFIG_SERIAL=y
CONFIG_UART_ASYNC_API=y
CONFIG_UART_1_ASYNC=y
CONFIG_UART_1_INTERRUPT_DRIVEN=n

• Build Configuration

west build --build-dir c:/Users/abdu/nrf/hello_dect/build c:/Users/abdu/nrf/hello_dect --pristine --board nrf9151dk/nrf9151/ns -- -DEXTRA_CONF_FILE=overlay-eu.conf

I have also attached the project example with issue, as a comprised folder, if you would like to double check it.

Kind Regards,

Abdu
