[Article] NuttX on Ox64 BL808 RISC-V SBC: Emulated in the Web Browser
In olden times we had Computer Games (plus Operating Systems) on 5.25-inch Floppy Disks. And we’d boot the Floppy Disks (clackety-clack) on Apple II Computers with 64 KB RAM. Today (40 years later) we boot microSD Cards (clickety-click) on Ox64 BL808 RISC-V Single-Board Computers with 64 MB RAM. What if we could turn it into a Virtual Ox64 SBC that boots in our Web Browser? Exactly like an Emulated Apple II! In this article we… (1) Take NuttX precompiled for Ox64 (Without any modifications) (2) Boot it on the TinyEMU RISC-V Emulator (3) Create our own Emulator for Ox64 SBC (With minor tweaks to TinyEMU) (4) And run everything in our Web Browser (Thanks to WebAssembly) Here's the article: https://lupyuen.codeberg.page/articles/tinyemu2.html Lup

Re: [Article] NuttX on Ox64 BL808 RISC-V SBC: Bare Metal Experiments
Thanks Greg, Wireless 802.15.4 on NuttX sounds very interesting! It might run on Ox64 BL808, but the WiFi / BLE / Zigbee parts of BL808 SoC are closed source. Hopefully Bouffalo Lab will reveal the wireless internals someday. Right now NuttX runs on the 64-bit Core (D0) of the BL808 SoC, and it isn't connected to WiFi / BLE / Zigbee. In future we might port NuttX to the 32-bit Core (M0), so we can have the wireless features.

Re: [Article] NuttX on Ox64 BL808 RISC-V SBC: Bare Metal Experiments
The Zigbee support is interesting. NuttX does not have a Zigbee stack, but does have IEEE 802.15.4 which works with the same physical radio. The IEEE 802.15.4 logic is quite an accomplishment. The original development was done by Anthony Merlino and Sebasiten Lorquet. I see that there have been many recent commits for Xiaomi folks too. When Anthony used the xbee which is a native Zigbee radio, he had to re-flash the part for use with IEEE 802.14.5 I also ported/re-implemented 6LoWPAN for use with IEEE 802.14.5. That is a very powerful solution. I had intended to support 6LoWPAN with Bluetooth radios too, but never got around to it.

Thanks yf! I believe T-Head C908 and other C9xx RISC-V Cores will need the T-Head Errata for Strongly-Ordered Memory Type, according to this Linux Patch: https://patchwork.kernel.org/project/linux-riscv/patch/20210911092139.79607-3-guo...@kernel.org/#24450685 The post suggests that T-Head will switch to the new RISC-V Svpbmt Extension for newer RISC-V Cores.

Re: [Article] NuttX on Ox64 BL808 RISC-V SBC: Fixed the UART Interrupt and Platform-Level Interrupt Controller
Thanks Alan! Nope sorry I haven't tested on Sipeed M1s, I should get it someday. I'm preparing a PR that will extend the RISC-V MMU Flags from 32-bit to 64-bit, because: (1) T-Head C906 (BL808) needs us to set Bits 59 to 63 in a Leaf Page Table Entry to configure the Memory Type: Cacheable / Bufferable / Strongly-Ordered (2) Newer RISC-V Cores will use the Svpbmt Extension (Bits 61 to 62) to configure the Memory Type (Cacheable / Strongly-Ordered) More about Svpbmt: https://github.com/riscv/riscv-isa-manual/blob/main/src/supervisor.adoc#svpbmt Lup On Sun, Dec 10, 2023 at 10:04 PM Alan C.

Re: [Article] NuttX on Ox64 BL808 RISC-V SBC: Fixed the UART Interrupt and Platform-Level Interrupt Controller
Hi Lup, Nice to know you found the issue (and Linux errata for T-Head C906 helped), that BUG is really strange. Probably a similar issue could exist on MILK-V board too. Did you test NuttX on Sipeed M1s Dock AI + IoT BL808 RISC-V? Unfortunately Pine 0x64 doesn't ship to Brazil (probably many buyers let the boards return after getting notified of higher taxes from Brazilian Customs).

Lup, Another great article! One suggestion. In section 10 "Swap the SATP Register" You mention: "Huh? Our Applications can meddle with the I/O Memory? Nope they can’t, because the “U” User Permission is denied. Therefore we’re all safe and well protected! " I may have missed the reference, but this might be a place to introduce the idea that Kernel trampoline, eCalls, and so forth make use of kernel memory being mapped and available in all User address spaces so the Kernel's handling code does not have to immediately swap SATP to access its data structures. I know this is a large topic on its own, but am important trick to learn. Again, great article! Thanks!! -KenD
