I can see in latest SDK for K82, in mbedTLS 2.6.0 support for ECC P-521 curve cryptography is disabled.
E.g MBEDTLS_ECP_DP_SECP521R1_ENABLED definition is disabled.
I think this is becouse LTC supports 512 bit modulo as maximum.
But even I enable this flag and disable LTC usage by undefine
I still not able to pass any tests for P-521.
Does K82 port of mbedTLS include ECC P-521 software implementation ?
