Interested in knowing that if TrustZone feature is enabled in DragonBoard 410c? It seems the processor Cortex® A53 supports TrustZone. Thanks
yes, it is enabled...
... but the firmware that runs in the secure world is proprietary and provided by QCOM, and it is not possible (for now) to change it.
It is present in the hardware but is more or less impossible to access from user modifiable software. If you're interested in experimenting with TrustZone this Hikey more suited to your needs.
Note that although Hikey does allow access to TrustZone there is no support for signature checking the code it loads from eMMC so secure boot cannot be implemented on this platform (i.e. it is good for TZ develoment but not for deployment).
Thanks for all your replies. So for Hikey, I find it runs Android and Linux, rather than IoT OS, like Android things or Windows 10 IoT core. Any board that you are aware of can support any IoT platform, and also with access to TrustZone?
I don't think any of the 96Boards can do this. You might be able to get this working on RPi3 but I'm afraid you'd have to ask for details on their forums
Thank you so much!!!
When you say IoT platform access to TrustZone, are you referring to hardware featuring Cortex M SoCs as in latest ARMv8-M architecture OR hardware featuring Cortex A SoCs with standard TrustZone as we know it.
Dragonboard 410c does have Windows 10 IoT core running, officially announced by Microsoft - https://blogs.windows.com/buildingapps/2015/10/28/announcing-dragonboard-410c-support-in-windows-10-iot-core-arduino-partnership-updates/
Does that answer your question?
I refer to cortex A SoC, since DragonBoard 410c uses A53.Yes, Windows 10 IoT can run on DragonBoard, but as others mentioned, it is almost impossible to experiment DragonBoard trustzone
