The value for money is crazy on these boards, in my opinion. I'm planning on using these as a cheap replacement to a KVM. Flashing esp bus pirate (https://github.com/geo-tp/ESP32-Bus-Pirate) and leaving it connected to whatever device I want to control ( remotely in my case), is quite handy. The power draw is negligible so I just leave it always on connected to my wifi.

Very cool project. Congrats. I will be trying this out.
Two other project I saw that are somewhat related for those interested:
1. reddit community (r/xteinkereader) building an OS like ebook reader app for a small chinese ereader based on esp32-s3
2. Linux port for the esp32-s3. Interestingly, the S3 has an MMU but I don't think it was used in this project.

Bit of a noob question: is this limited to the S3 or can I try running it on a C3 too?

Well, I know what I'm doing next weekend.. I was already gonna pick up an esp32-s3 for another project, now I need two...

They are really cheap, get an esp32-c6 while you are at it.

Very cool! We need to get this on M5Stack Cardputer ASAP

Being instant-on is so, so cool. I really like seeing projects like this and Adafruit's Fruit Jam as they really show "Yeah, by having all this junk in the way, we do lose some things"
Absolutely would give something like this to a kid as a first computer.

I am looking forward to $20 laptops on aliexpress running this thing!

Doesn't the lack of a flat memory model make a genral os difficult? The amiga1000 had far less processing power and about the same memory, with no mmu, but that memory model was flat. Did you have to do weird things to work around it?

The memory model is flat enough. The problem with the memory is, you only have about 200kB traditional RAM. But then, you have 8MB of PSRAM. But it requires strict 4-byte alignment, and is noticeably slower.
What makes traditional OSs difficult on this platform, is the lack of memory protection. But I am a simple man, I am not writing an OS, all I wanted was a usable shell and an apps installer, so I made that work.

Can you expound on this problem a bit? I'm still pretty new to MCUs.

Hey you're the xcc700 guy! Very cool stuff. I've been interested lately in using MCUs for general purpose compute. I wonder how far you could push it.

Right, people were asking about the shell used in the xcc700 demo, so that is released now too, and I tried to make it convenient to reuse as a component.
Esp32-s3 can do so much more, we are just scratching the surface. You might remember FabGL, that ran some nice demos in the realm of games and DOS emulation. Unfortunately, seems to be hard to update for modern versions of ESP-IDF. I am trying to build something more modular, with hope that some parts of it will survive longer.
I think someone also ran an old version of MacOS simulated on it, too, that is also an indication of the general capability.

Would it be possible to port it to run on the rp2350?
6 hours ago
Some parts of it, very likely. The shell is just linenoise with some glue code. How are things with ELF loading on rp2350, I did not check. May be possible, the question is, how much effort. In ESP-IDF that is a standard component now.
4 hours ago
rp2350 supports freertos, so a similar port should be fairly trivial.
The io DMA code is a little special on the Pico. Very capable little chip. =3

This is my introduction to Breezybox and THAT I am really excited about. I hate that for some reason I have to care about Wifi configuration and updates, I just want to write my application. I never understood why we don’t have simple microcontroller OSes that care about that stuff for us.
This looks like a great basis (or maybe even all that’s needed) for one.
Does it have a good setup flow for headless deployment (e.g. supply Wifi config while flashing, remote shell access/web UI for deploying apps)?

Cool project!
