Why is RTEComponents.h not updated correctly?

[syntroniks]

I have enabled a gpiote module, it does not set gpiote_enabled to 1. I have tried deleting the file in the RTE folder with no success. I have tried disabling and enabling that component. I have also tried deleting rte_components.h

As an aside, I tried to enable the TWI module and TWI_COUNT, etc. are not defined. I can only imagine they should be present in nrf_drv_config.h

The file defines this:

#define GPIOTE_CONFIG_NUM_OF_LOW_POWER_EVENTS=4>nrf_drv_gpiote
#define GPIOTE_ENABLED=1>.
    #define GPIOTE_CONFIG_NUM_OF_LOW_POWER_EVENTS=1>.
#define S110
#define SOFTDEVICE_PRESENT
#define SWI_DISABLE0

But nrf_drv_config.h defines this:

#define GPIOTE_ENABLED 0

#if (GPIOTE_ENABLED == 1)
#define GPIOTE_CONFIG_USE_SWI_EGU false
#define GPIOTE_CONFIG_IRQ_PRIORITY APP_IRQ_PRIORITY_HIGH
#define GPIOTE_CONFIG_NUM_OF_LOW_POWER_EVENTS 1
#endif

This looks like a bug

I think the intent of nrf_drv_config.h is that you edit it for your project purposes. The on-chip peripherals are disabled unless you need them, in which case it is your task to enable them.

On my project I use TIMER2, so I have to change

#define TIMER2_ENABLED 0

to

#define TIMER2_ENABLED 1

I can see that being the idea, but then that overrides RTE_Components.h which I can't imagine is intended behavior. Perhaps the two files are meant to be mutually exclusive and I have got my project in a misconfigured state.

@syntroniks: I agree with Nick, if you want to use the module in your code, you would need to modify nrf_drv_config.h as you need. It won't be updated automatically.

@Syntroniks: I just got confirmation from our developer it's the bug in the SDK v8.1. nrf_drv_config.h wasn't updated correctly. You would need to add:

    /* TWI */
#define TWI0_ENABLED 0

#if (TWI0_ENABLED == 1)
#define TWI0_CONFIG_FREQUENCY NRF_TWI_FREQ_100K
#define TWI0_CONFIG_SCL 0
#define TWI0_CONFIG_SDA 1
#define TWI0_CONFIG_IRQ_PRIORITY APP_IRQ_PRIORITY_HIGH

#define TWI0_INSTANCE_INDEX 0
#endif

#define TWI1_ENABLED 0

#if (TWI1_ENABLED == 1)
#define TWI1_CONFIG_FREQUENCY NRF_TWI_FREQ_250K
#define TWI1_CONFIG_SCL 0
#define TWI1_CONFIG_SDA 1
#define TWI1_CONFIG_IRQ_PRIORITY APP_IRQ_PRIORITY_LOW

#define TWI1_INSTANCE_INDEX (TWI0_ENABLED)
#endif

#define TWI_COUNT (TWI0_ENABLED+TWI1_ENABLED)

to the file.

Regarding adding gpiote, if you only add nrf_gpiote component, there will be nothing change, because it's just a hal layer. If you add nrf_drv_gpiote, you will see RTE_Components.h gets updated.

We fixed the issue with TWI in SDK v9.0.

OK TY Hung for your follow-up. I love the new Keil pack thing when it works. I'll try converting your comment to an answer and accepting it.
