The chip comes from the factory with a boot0/boot1 chain that is fully reproducible and buildable from source. Developers can replace boot1 with their own version, where you could add the feature you're thinking about.

Thanks! One last question is whether it can boot from external EEPROM? This is mainly with reference to Ken Thompson’s Reflections on Trusting Trust paper (https://www.cl.cam.ac.uk/teaching/2324/R209/Reflections-Trus...).

What would be good is to be able to program the eeprom with hardware, boot the bao with the eeprom and then bootstrap the rest of the OS.

Lastly I was thinking on the inclusion of 4 bidirectional (transputer) links so to speak. I’m guessing you’ve thought about clusters of these chips?

Thanks
