STM32L431 Software CRC

[ABlam.1]

Hello, does anyone know how to programmatically calculate a CRC using the same algorithm than the one provided by the CRC module of STM32L431 ? Can ST just provide a up-to-date documentation/application note providing the implement CRC algorithm on STM32L431 ?

I tried to use the algorithm described in AN4187 but nevertheless it's not the good one (just try to compute the CRC example described on AN4187, you'll get 0x80 instead of 0x4c).

Thanks
