Hi all

Apologies for my relative silence; I have been looking at this - promise!

Depending on your requirements, if switching to Fortuna[*] doesn’t solve your problem (Fortuna will be the default some time in the future anyway), then try this hack:

In yarrow.c, line 156, change

yarrow_state.seeded = 0;

to

yarrow_state.seeded = 1;

M

[*] In your kernel:

options         RANDOM_DEBUG		# Expose the reseed progress
options         RANDOM_FORTUNA          # Use the Fortuna CSPRNG
