Hello Hanno, Thanks for your thanks for you quickly replay.

I have an error compilation, I'm using nios2-linux-uclibc for my cross compilation and uclinux architecture,
the linux kernel is 2.60 but I have this error when I try to compile the library, I want to use the library as a simple client using TLS1.2

Hi Palomo,

Please take a look at the recent thread https://lists.trustedfirmware.org/pipermail/mbed-tls/2020-April/000069.html 
which should give you a better understanding of how Mbed TLS manages and uses entropy from the underlying system.

Regards,
Hanno

Hi all!

I'm Palomo and I've been working with your library a few weeks ago, I'm using Linux kernel 2.60 but my embedded system has a limit entropy source, i now that this is a critical point, but How can I use your library if I want to use a other entropy source? 

Thanks and waiting for you!
