Hi I found this email on ARM MBED support forum. Could you help to resolve our issue?

On the PSoC6 device we are using mbedtls_rsa_gen_key function with a good hardware TRNG passed FIPS 140-2 verification. This function verifies generated random pair and requests new pair if they don't follow FIPS 186-4 criteria. The number of verification loops is between 1 and 6 in worst case. Is it expected behavior? The arithmetic of one loop takes a lots of time. How can we improve the random number to have always pass FIPS 186-4 in a one loop?

Thanks Nazar
