Kudos Lup! It is an interesting aproach to get familiar with NuttX I suggest presenting it at the NuttX workshop Best regards Alin On Sun, 14 Jan 2024, 08:17 Lee, Lup Yuen, wrote: > Thanks Alan!

Re: [Article] NuttX in the Web Browser (TinyEMU + VirtIO)
Thanks Alan! Yep "The Construct" looks like a cool way to learn ROS online, we should do something similar for Teaching NuttX Online! As for Emulated Networking in the Web Browser: TinyEMU Emulator supports VirtIO Networking. But it's tunnelled through a WebSocket VPN, because of browser limitations. I might test this with NuttX and see how well it works. (I'm also keen to emulate Ox64 BL808 RISC-V SBC in the Web Browser) TinyEMU VirtIO Networking: https://bellard.org/jslinux/tech.html WebSocket VPN: https://www.benjamincburns.com/2013/11/10/jor1k-ethmac-support.html Lup On Sun, Jan 14, 2024 at 8:10 AM Alan C.

Note to self: Check whether above-linked wiki page has been migrated to Documentation in the repository and, if not, migrate it... I likely won't be able to work on that until next week, so if someone else wants to do it, feel free. :-) Cheers Nathan
Re: [Article] NuttX in the Web Browser (TinyEMU + VirtIO)
Really cool Lup! Maybe it could be used for training and deduction purposes. Do you know "The Construct" they are using a solution like that to run Linux in the browser: https://app.theconstructsim.com/login/ Is it possible to get network enabled and use it to communicate? It could open new possibilities! BR, Alan On Sat, Jan 13, 2024 at 8:30 PM Lee, Lup Yuen wrote: > NuttX now boots and runs inside a Web Browser!

WOW! CONGRATULATIONS LUP!! :-) -- CeDeROM, SQ7MHZ, http://www.tomek.cedro.info
[Article] NuttX in the Web Browser (TinyEMU + VirtIO)
NuttX now boots and runs inside a Web Browser! (With WebAssembly) Try "ostest" here: https://lupyuen.github.io/nuttx-tinyemu This article explains how we… (1) Boot NuttX in the Web Browser with TinyEMU RISC-V Emulator (2) Modify NuttX for HTIF Console (Berkeley Host-Target Interface) (3) Explore VirtIO Console with OpenAMP Library (4) And how we might use it: Emulate NuttX Gadgets in the Web Browser? A Real-Time NuttX Dashboard that lights up as the various NuttX Drivers are called? Here's the article: https://lupyuen.codeberg.page/articles/tinyemu.html How will you use NuttX in a Web Browser? Please lemme know Lup
