STM32 CryptoLib - Verifyin on Linux machine

Hello everybody,

I'm tryin to make a Nucleo-F401 sign a message and then verify this message on a Linux machine. Currently I am able to inject both private and public key into the STM32F401RE (and, starting from ECDSA keygen and sign example, I checked that it works). However, the public keys given by Python ECDSA and CryptoLib are different. Since I'm using the same curve for both (FIPS 186-3 NIST256P), what can cause this behaviour?
