Where can one find docs for this?
The latest Hexagon SDK I can find is 3.5, which still ends at v67.

I guess the folks at developer.qualcomm.com are behind in publishing specs.  I'll work on getting these.

Thanks,
Taylor

Hi Richard,

The documents have been posted on this page in the Documentation section.
https://developer.qualcomm.com/software/hexagon-dsp-sdk/tools
I'll update the README with the link to the latest versions.

Are you planning to review these given that Anton Johansson <anjo@rev.ng> has already done a review?  If not, I'll go ahead and do the pull request.

Thanks,
Taylor

Go ahead with the pull.  But thanks for the documentation update.
