Config impacts in prj.config

[MontanaEE]

Trying to set up UART/UART0 for async.  I cannot get the uart interrupt config to shut off.

CONFIG_UART_INTERRUPT_DRIVEN=n  is set in the prj.conf 

In config output, this field is still set:

CONFIG_UART_INTERRUPT_DRIVEN=y

I do not have access to Kconfig as this is being set up on the Laird/Ezurio Pinnacle 100 DVK which uses and out of tree build.

How can I see which config is locking the Uart Interrupt Driven on?

Thanks

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

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

CONFIG_UART_0_ENHANCED_POLL_OUT=y

# CONFIG_UART_0_INTERRUPT_DRIVEN is not set

CONFIG_UART_0_ASYNC=y

# CONFIG_UART_0_NRF_PARITY_BIT is not set

CONFIG_UART_0_NRF_HW_ASYNC=y

# CONFIG_UART_0_NRF_ASYNC_LOW_POWER is not set

CONFIG_UART_0_NRF_HW_ASYNC_TIMER=0

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.
