Hi,I am struggling to get `HAL_PKA_ECCCompleteAddition` implemented correctly, that is, if I'm comparing the projective coordinates with a reference implementation, the results don't match. Same goes for converting the projective coordinates back to ...

Note: In this example, the `Y` coordinate in ecc_secp256r1_add_points_projective is correct, but the `X` and `Z` coordinates not, and of course the affine result is then also incorrect.

Thanks for your response, and the (Montgomery) implementation reference (see below about that).For a reference I use 2x multiplication of the generator base point, see below snippet. `double_origin_expected` gives the same results as in a python impl...
