Hi guys,
I would propose you take a good look at the NRFs errata sheet: it's (i)
quite long and (ii) tells you lot's of things that work on one stepping
but do not work on another... I took my for example quite some time to
find out, that my NRF bords have their timers fixed to 24-bit width (as
opposed to the description in the datasheet..) I could imagine the RNG
module is also effected...
Cheers,
Hauke

hello frank
sh... - oh great....
if you find time maybe you can tell me more about the POWER
reg/address. I read the man and power section etc. but still dont know
how to calculate POWER 0x00000ffc.
ps. my dk should arrive in some hours... so i have an alternative
board(s) - test performed on rfduino...
thanks for your input hm output :)
