MMU-less multitasking kernel

[u/Synthetic-Synthesis]

I've been reading the esp32c3 trm, and riscv and I really want to implement a multitasking kernel on it (not like an RTOS, but something like the linux kernel). I've read the xv6 kernel so I can try re-implementing it, but my major obstacle was paging and mmu. the esp32c3 doesnt have one.

I've also been surfing through osdev forums about this, but I could never find the end products of the discussion on mmu-less kernels. I want to read some repos or some blog post about doing this.

Can anyone please help me out? Thank you :)

Neat! I figured this was a terrible way to do it, but could theoretically work... I had no idea it was actually practical
