nRF Connect SDK/ startup files & interrupt vector table

[jot.pyka]

Hi,

I'm trying to integrate https://github.com/nrfconnect/sdk-nrf in version v1.9.1 in my baremetal application (nRF5340 NET and APP CPUs). Where can I find the startup files and the interrupt vector table within NCS I could use for my application ? I was previously using the nrfx where under https://github.com/NordicSemiconductor/nrfx/tree/master/mdk I could find the files I asked about e.g. gcc_startup_nrf5340_application.S. So the general question is how does that work in NCS ?

BR,

Jaroslaw

Hi Jaroslaw,

Code found in the nrf repo is tightly coupled with the Zephyr OS and I don't really see how it can be integrated into a baremetal application. Are there specific parts you are looking to integrate with your project?

The vector table is populated by the build system in the nRF connect SDK and it requires that the ISRs are defined a certain way in your application: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/zephyr/reference/kernel/other/interrupts.html#defining-a-regular-isr

Best regards,
