https: could not get entropy input :Error

https: could not get entropy input :Error
Hi

I am trying to get https working with ipxe. I enabled HTTPS in config/general.h (#define DOWNLOAD_PROTO_HTTPS)and then compiled the efirom with following command.

make bin-x86_64-efi/80861521.efirom;

I flashed this binary to i350 flash (after padding adjusted to flash size).

However i get the following message during reboot

DRBG 0xdaf1bf90 instantiate
DRBG 0xdaf1bf90 could not get entropy input: Error 0x7f4ee083 (http://ipxe.org/7f4ee083)

Any further attempts to initiate https download results into following message and causes reboot(chain https:...)
DRBG 0xdaf1bf90 not valid
Could not start download: Invalid argument (http://ipxe.org/1c416082)


I am running this on intel i5-4402E.

Any ideas how to debug and fix this issue?

thanks
ms

RE: https: could not get entropy input :Error
iPXE fails to generate enough randomness to be happy, could you enable debug to see exactly where it fails?

make bin-x86_64-efi/80861521.efirom DEBUG=efi_entropy

Read the FAQ before posting.
Did you include relevant ipxe.org error urls?
