Re: [tinydtls-dev] master-key generation problem

Hi Olaf,

I tried to dig a bit deeper but I'm not finding much answers. However the main logic like key length/copying keys etc. works fine. I've debugged a x86 version of the dtls-server example supplied by the library and it works the same way. However on my CC2538 platform the result of the master key is plain wrong.

I am not sure where the problem is but my guesses are that I either have a stack/memory problem where the memcpy functions are just copying the wrong values or the SHA_XXX() functions or the SHA256 functions are delivering different values on my platform.

Not sure what's more feasible.

Are you using PSK or ECC (with raw public keys) for your tests?  (The
code for parsing raw public keys had an error in older versions of
