Unable to Generate Public Key for ESDSA on nRF52832 - NCS

Question

Hardware: nRF52832 
 Software: NCS(v2.5.2) 
 Hi i want to generate public key using for ESDSA . 
 I am trying to run this example (samples\crypto\ecdsa\src ) for nrf52832 board but not able to generate public key. 
 getting this error 
 
 "psa_generate_key failed! (Error: -134 )" 
 
 For nRF52840 it is working fine, but i want to implement same in nrf52832. 
 what changes i need to do to generate public key using ESDCA example?

Hi Mehul, 
 Good, you found the additional missing configs for 2.5.2. These configs enable AES, and that is used for the CTR-DRBG algorithm (the nRF RNG acts as a TRNG is the entropy source, and that is feed into CTR DRBG algorithm to provide random data to the application.
