I see. You are correct that some people have accused ARM devices like Rockchip ARM64 boards of not being fully open source and have made claims about TrustZone being a hidden backdoor similar to Intel ME. However, as I mentioned earlier, TrustZone is not a hidden operating system or a backdoor. It is a well-documented and widely used technology that provides hardware-based security for ARM platforms.
ARM devices may not be 100% open source, as they may use proprietary firmware or drivers, but the majority of the software stack is open source. Furthermore, some chip manufacturers such as Rockchip provide public access to their hardware documentation, kernel source code, and other software components for their devices.
It's important to keep in mind that the software and hardware landscape of embedded systems like ARM devices is complex, and every device and vendor has their own unique set of challenges and tradeoffs. If you're concerned about the security or transparency of your ARM device, it's a good idea to research the specific device and vendor thoroughly or consult with experts in the field.
