Running wolfEntropy on PetaLinux 2025.1 with ZCU102
wolfEntropy is a jitter based source of entropy provided by wolfSSL. Evaluating entropy sources is a critical step when building secure systems, especially on embedded platforms where hardware RNG behavior must be validated. This post walks through running wolfEntropy on PetaLinux 2025.1 targeting the ZCU102 Evaluation Kit platform and reviewing the results. The outcome: the […]
