compilation problem (SWI1_EGU1_IRQHandler)

[astella]

To the kind attention of Nordic support team,

I have a project that is exploiting either gzll or BLE protocol. I'm using gzll_nrf52840_sd_resources_gcc.a libraries, that have been included in the project. In addition, I'd like to make use of radio notifications when BLE is working, and introduce my custom SWI1_EGU1_IRQHandler in the project. That is giving to me compilation troubles, as SWI1_EGU1_IRQHandler appears to be already defined in gzll libraries. Is there a solution you could suggest in order to overcome this issue?  

Best regards

Hi,

You can find the resources used by looking the gazell user guide;
https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.1.0/gzll_02_user_guide.html#gzll_resources

So in your case you need to use a different software interrupt than 1, since it's used by the gazell library:
https://infocenter.nordicsemi.com/topic/ps_nrf52840/swi.html

Edit; I can see your problem now, since radio notification also use software interrupt 1, ref the softdevice spec:
https://infocenter.nordicsemi.com/topic/sds_s140/SDS/s1xx/sd_resource_reqs/app_signal_sw_interrupt.html

I guess you need to use gzll_arm.lib (software interrupt 0) instead of gzll_sd_resources_arm.lib (software interrupt 1) in this case.

Best regards,
Kenneth
