[Buildroot] /dev/hwrng no such device error

Hello,

I am trying to gather more entropy in my nonblocking pool.
So I have compiled the the *rng-tools* module via buildroot, and I have
activated the *HW_RANDOM_INTEL* in the  kernel configuration.
However, I cannot read from /dev/hwrng and I cannot execute the rngd
service.
I have these messages :
*# rngd -v*




*read errorread errorAvailable entropy sources:        Intel/AMD hardware
rng        DRNG*

Also, the  file */sys/class/misc/hw_random/rng_available* is empty. And,
the" */sys/class/misc/hw_random/rng_current*" has "*none*"

Did anyone faced the same problem before ?

Kind regards,
Omar
