TPS65381 initial programming



Hi,

Can you advise if a new TPS65381 would need programming prior to initial bringup on a board?

I've got some samples laid down onto a custom schematic (which closely resembles the EVM board schematic), but they aren't coming out of reset state: covered the obvious so was wondering whether initial setup of the NVRAM was needed before they'll reach diagnostic mode?
