Oh an look it's another Fabrice Bellard[1] project that enabled it:

> I've looked into QEMU emulation for RISCV but taking this project apart and getting only a few components out of it to run on an embedded system seemed like too much work. Eventually I've found out about Fabrice Bellard's TinyEMU

Wow 1:35 is pretty fast. That's as fast as a rasp pi zero!

Interesting comparison, though I assume the Rpi zero elapsed times include a lot more onboard peripherals for the kernel to figure out. I think I'm only counting five devices in the boot output for this ESP32. And nothing time consuming to configure, like a network device.

A more interesting candidate for the ESP32 would be Inferno OS. It's a Desktop OS which doesn't require a MMU and needs about 1MB RAM on startup. As a bonus you get all the benefits of plan 9.

Thanks for pointing out Inferno OS. I recently started tinkering with embedded devices after a long gap, and this looks like perfect project to work on!

it helped me to understand the authors motivation by reading his 5 year old post on the esp32 https://blog.drorgluska.com/2017/09/esp32-as-professional-gr...
