DPPI Channel Mask vs GPIO0 pin Mask

[jmerri95]

Hello, 

I am relatively new to the nrf9161, but I am running into an error with my build.

'TFM_PERIPHERAL_DPPI_CHANNEL_MASK_SECURE' undeclared (first use in this function); did you mean 'TFM_PERIPHERAL_GPIO0_PIN_MASK_SECURE'?

For context, I am trying to configure 3 pins (6, 7, 24) within the application using GPIO_DT_SPEC_GET. 

const struct gpio_dt_spec interupt_pin = GPIO_DT_SPEC_GET(ZEPHYR_USER_NODE, interupt_gpios);

I am programming to a nrf9161 DK., tool chain 2.7.0

thank you, 

Jack

Hi Jack,

Thanks for checking with us. This kind of error is most likely due to misconfuration.

I am not sure which smaple you are based on. Can you refer to the GPIO_DT_SPEC_GET usage in zephyr\samples\basic\button? It should work direclty with nRF9161DK.

Best regards,

Charlie

I encountered the same error. I explored the target_cfg.c and target_cfg.h files (located at C:\ncs\v2.6.0\modules\tee\tf-m\trusted-firmware-m\platform\ext\target\nordic_nrf\common\core), but the execution followed the else path.

#if NRF_SPU_HAS_MEMORY
    /* There is only one dppi_id */
    uint8_t dppi_id = 0;
    nrf_spu_dppi_config_set(NRF_SPU, dppi_id, TFM_PERIPHERAL_DPPI_CHANNEL_MASK_SECURE,
			    SPU_LOCK_CONF_LOCKED);
#else
	/* TODO_NRF54L15: Use the nrf_spu_feature API to configure DPPI
	   channels according to a user-controllable config similar to
	   TFM_PERIPHERAL_DPPI_CHANNEL_MASK_SECURE. */
#endif

To resolve the issue, I deleted the build configuration and reconfigured it with secured firmware (not the 'ns' one).

The error was resolved.

Kind Regards,
