SAHARA PRNG

Hi,

 

I'm trying to generate some random numbers using the SAHARA lite on iMX51. When I try to generate the random number, there is an error in the ERROR STATUS register with 'error source' set to 3. (invalid descriptor pointer / length).

 

The descriptor which I load looks like this :

Header --> Desc #18

Len1  -> Number of random bytes needed

Ptr1 --> Pointer to link node

Len2 --> 0

Ptr2  --> NULL

Next --> NULL.

 

Link Node :

len --> num of bytes needed

ptr --> pointer to the data buffer

next --> NULL

 

Is the descriptor format correct? There's no example in the security manual.

Thanks
