Hi 

I understood that for generating random numbers we have to instantiate RNG and then generate random number(with job descriptors) and we will be using job ring registers to do the operation...

 

1.May i know how to read the generated random number? Is it possible?

2.The number which i will be reading is the correct number or the encrypted one?

 

I tried to execute it with sdk rng job descriptors...

3.How i will understand whether the random number is generated or not?

 

job ring output status register is

CAAM_JRSTAR0 = 0x40001f04

 

Thanks in advance
