Hardfault when linking OpenThread library

Hi Joakim and Daniel,

Thank you for the response. Here’s the gist of the .map file: https://gist.github.com/jia200x/55f87ac2d966bafb604fb17ff577a7d8

I’m using a SAMR21-xpro.

I have only written the platform abstraction hook functions, so I haven’t initialized objects. I’m checking all pointers now.

Best regards, Jose
