That looks like rather little memory (768k SRAM; 32MB “PSRAM” has some sort of catch - is it serial-attached and slow?) You’d have a chance with Inferno though: similar to David Boddie’s microcontroller ports https://github.com/dboddie/inferno-os (look at branches) except riscv instead of arm. I haven’t heard of a port to ESP-riscv chips being done yet. If the LoRa devices with nice screens and keyboards (like LilyGo T-Deck series) would start using the Risc-V ESP chips, I might be somewhat interested in that too. But I’m busy enough with the Plan 9 port for now, which is for Spacemit K1 and K3 so far (much more memory and performance).
