Hi Experts,

I am asking for my customer here.

When migrate ECSDA Project from F280049 to F28P55x,  sig_r_val and sig_s_val do not have any vaule during step by step debug?

When we step into this function about ecc_sign_hash(hash, hashlen, curve_name, private_key, per_message_random_number, sig_r_val, sig_s_val, &prng);

When it run into while(1), and then it will Generate the signature and store r and s values in sig_r_val & sig_s_val respectively, but we do not see any values here. Could you help us look into this issue?
