Config impacts in prj.config

Hi there,

I see that the defconfig file for the board that you are using is setting CONFIG_SERIAL=y.

But the prj.config file should have precedence over this, so I assume that there is something else in your application build that is forcing CONFIG_SERIAL=y and CONFIG_UART_INTERRUPT_DRIVEN=y.

Can you try to open up the kConfig menu in VS Code and then go through all of the kConfigs dependencies and see if any of them are forcing it to be enabled?

If you can share a minimal sample that would reproduce the issue then that would be great!

regards

Jared

Yes I can change some configurations just these few for uart interrupt are not changing. Where would they have "locked" these configs? I cannot find reference to anywhere that would be taking place.

Thanks Elfving,

UART_0 interrupt is turned off, but I cannot get UART interrupt to be disabled.

This is what I have in proj.conf:

CONFIG_UART_INTERRUPT_DRIVEN=n
CONFIG_UART_0_INTERRUPT_DRIVEN=n
CONFIG_NRFX_UARTE0=n
CONFIG_SERIAL=n
CONFIG_UART_ASYNC_API=y
CONFIG_UART_0_ASYNC=y
CONFIG_UART_0_NRF_HW_ASYNC=y
CONFIG_UART_0_NRF_HW_ASYNC_TIMER=0
CONFIG_UART_USE_RUNTIME_CONFIGURE=y

This is what is in the resulting .config output:

CONFIG_UART_INTERRUPT_DRIVEN=y

CONFIG_SERIAL=y

CONFIG_SERIAL_HAS_DRIVER=y

CONFIG_SERIAL_SUPPORT_ASYNC=y

CONFIG_SERIAL_SUPPORT_INTERRUPT=y

# CONFIG_UART_LOG_LEVEL_OFF is not set

Hello Stephen,

I am not used to out of tree builds like these, but I wonder if it might be locked that way.

Could you try setting these configurations:

CONFIG_UART_ASYNC_API=y

CONFIG_UART_0_ASYNC=y

CONFIG_UART_0_INTERRUPT_DRIVEN=n

Are you able to enable any configuration for this build?

Regards,

Elfving

Went through all of the configs that were listed as selectors for the interrupt driven option. Made sure they were set to "n" to disable, still interrupts are set to "yes" in the config.
