That’s a shame, it’d be a cool and, afaik, unique feature for this niche.

That’s a shame, it’d be a cool and, afaik, unique feature for this niche.
- Rochus 6mo agoMaybe Espressif will notice that there are no RV32 chips with MMU so far (at least to my knowledge); we only have 32 bit MCUs or then only 64 bits for the CPUs. Something like Cortex-A7 is missing.
- GeorgeHahn 6mo agoThere’s one incoming, https://baochip.github.io/baochip-1x/ https://baochip.github.io/baochip-1x/ It would be great to see more.
- volemo 6mo agoBaochip looks very interesting, and I highly respect bunnie's work, but I can't realistically say Baochip is a viable option for me, an unprofessional tinkerer.
- bschwindHN 6mo agoThe upcoming Baochip is an RV32 chip with an MMU, I believe. https://www.bunniestudios.com/blog/2026/baochip-1x-a-mostly-open-22nm-soc-for-high-assurance-applications/ https://www.bunniestudios.com/blog/2026/baochip-1x-a-mostly-... Edit - Oops GeorgeHahn beat me to it
- IshKebab 6mo agoDoes anyone know what CPU this uses? Is it their own first party design?
- peteforde 6mo agoNot sure I understand your question, but the ESP32-S3[1] is the "CPU" here.
- forsakenharmony 6mo agoESP32-S31 (very different from the S3)
- peteforde 6mo agoThat's literally and exactly what I said.
- volemo 6mo agoTo be fair to GP, I too was confused by your use of brackets here.
- peteforde 6mo agoI wasn't trying to be obtuse. Formal grammar / technical documentation style guides consistently define: [ ... ] = optional { ... } = repetition | = alternatives
- IshKebab 6mo agoHacker news isn't a formal grammar specification though. People use [1] for references here too (which you could easily have forgotten).
- IshKebab 6mo agoThat's the SoC. The CPU is a small part of it. For example they could be using an open source design like the CVA6, or a commercial design from someone like Andes.
- peteforde 6mo agoEspressif has a designed-in-house RISC-V CPU, so far as I know.
