The juice virtual machine was born in 2020, with the goal of realizing the smallest virtual machine of RISC-V that can run the latest kernel mainline. At the beginning of the design, it runs on a platform with only 100 KB of RAM, which does not exceed the number of C99. Three-party dependence.

7 points · Open discussionThe MMU is not really a requirement in this situation, a processor with a real MMU is emulated in software[1] on the ESP32 (this is the virtual machine referred to in the article and comments)

It seems to be booting a riscv vm, which is capable of running linux. The hardware capabilities of ESP32 is not very important(except being fast enough).
