I'm also looking for a solution to enable secure boot with encrypted SD card and so having a few questions:
1) Is this method applicable to H5 also or it will work only on H3?
2) Are data stored in eFuses (encryption key) are secured? Can someone with physical access to device read them?
3) This topic is very important for IoT devices that store sensitive data in their memory so it will be very helpful if you guys could provide step-by-step instructions on how to enable secure boot with storing an encryption key in eFuses (for newbies to this platform).
