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,

Which SDK version are you using, and which application is currently running on the DK?
Could you try recovering the DK once and see if that removes the app protection?

Kind regards,

Hello,

I am currently using SDK v3.0.

I am using customized hello_dect application in addition to reading data on uart1.

I have tried that, but still the same issue.

I have found that, if i remove CONFIG_UART_ASYNC_API config, then the protection issue is gone.
Is there a solution for that, as i intend to use UART_ASYNC_API?

Kind regards,

Abdu
