Is there a way to bootstrap binary code into the reram? I’m thinking being able to ‘hand-type’ in a few hundred byte kernel rather than use a flashing tool
- bunnie 6mo agoThe 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.
- alexisread 6mo agoThanks! 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-Trusting-Trust.pdf 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
