Doesn't reach main nrf52810

Thanks for the update. I tried the same here now, and seems like IAR automatically calls a function named __iar_init_vfp in the startup code if you include a library compiled with HW FPU float support. And this function includes FPU instructions, so I guess that explains the hardfault.

Hi, Vidar!

Thanks!

Problem was in using micro_ecc_lib_hrf52.a

It is now changed to micro_ecc_lib_nrf52.a

I have not suggest that library (with using FPU) has effect to initialisation process before main.

Issue is solved.

Thank you for help!

Hi,

Please make sure you're using system_nrf52810.c and not system_nrf52.c in your project. This hardfault may occur if you try to access the FPU HW which the 52810 doesn't have.
