Re: [riot-devel] Hardfault when linking OpenThread library

[Jose Alamos]

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

Re: [riot-devel] Hardfault when linking OpenThread library

[Joakim Nohlgård]

What platform are you running this on?
Could you post your .map file? (preferably as a link to gist or pastebin or
similar, since they tend to be very large)

Best regards,
Joakim
