Hikey Trustzone documentation

Hi there everybody,

I am looking to find some details on which hardware components are integrated into the Hikey board for ARM Trustzone and security features in general.

Tried looking at the Hikey User Guide and the Kirin 620 datasheet but the only thing I find is that the board supports ARM Trustzone but I would interested in knowing the actual implementation (e.g TZIC, TZWDOG,…) and any further security related components on the board/processor.

Kind regards,


Hi Merlijn,

I am not an expert in this area, however, today’s OpenHours topic is going to cover TrustZone on Hikey. Joakim Bech @jbech and Daniel Thompson @danielt, two of our Tech Leads who will be on hand to answer any questions you may have around security and Trustzone on the HiKey. You are welcomed to join and ask any questions directly to them :slight_smile: (I will also notify them about this forum post)
