Hi,

pca10040 is for the nRF52 DK board which targets the 52832 with 64K RAM whereas your chip only has 24K. Try the pca10040e project instead. This configuration is really for the 52810, but it may work still as it shares the same memory configuration as the 52805 has.

Hi Vidar,
I used pca10040.

Hello,

Which project configuration did you use (pca10040e, pca10056, etc) when you built the blinky project? Hardfaults before reaching main() are typically caused by incorrect linker settings (i.e. invalid memory configuration for the target device).

Instructions on how to configure the linker for the nRF52805 is described in this guide: Developing for the nRF52805 with nRF5 SDK

Best regards,

Vidar
