Hi@gnij_uy

There is an example code which using randum number generator .

You can download AN5401 & AN5401SW by searching the key-word AN5401 on the NXP webside.

and please take a look at Example3_Basic_operations_SDK3_0_0.

BR!

Hi@gnij_uy

   you have to take a look at  AN5401, expecially 4.3.1 Random number generation. If you don't read the manual carefully, it is easy to cause your EVB to be locked when using AN5401SW.
    Some steps must done before using RNG, such as the device must be configured for emulated-EEPROM operation, maybe you can try to modified the example of Example1_Configure_part_and_Load_keys_S32K3_0_0.

BR!
