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,

Could you check whether enabling the configs CONFIG_NRF_APPROTECT_USE_UICR and CONFIG_NRF_SECURE_APPROTECT_USE_UICR resolves the issue? This way, it follows the UICR values rather than force-locking at boot. See the documentation here.

Kind Regards,

Abhijith

Hi Abhijith,

I have added both configs  CONFIG_NRF_APPROTECT_USE_UICR and CONFIG_NRF_SECURE_APPROTECT_USE_UICR, but i still have the same issue

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=1

# 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

CONFIG_NRF_SECURE_APPROTECT_USE_UICR=y
CONFIG_NRF_APPROTECT_USE_UICR=y

 

Best regards,
