Really cool Lup! Kudos!!!
Actually booting NuttX from a floppy drive should be really nice too.

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.
Happy New Year NuttXers,
Really cool Lup! Kudos!!!

Happy New Year! 2024 is here and we’re running NuttX on Single-Board
Computers with plenty of RAM. Like Pine64 Ox64 BL808 SBC with 64 MB RAM!
In this article, we create a Blinky LED app with a Python-like,
Garbage-Collected Language that compiles to C: Nim Programming Language.

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
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
Congratulations Lup!! :-)

Pine64 Ox64 BL808 (64-bit RISC-V SBC) is now supported in NuttX Mainline!
(Many thanks to my reviewers)
Ox64 BL808 is an affordable $8 SBC with:
- 3 x RISC-V Cores (T-Head 64-bit / 32-bit)
- Networking: Ethernet, WiFi, Bluetooth LE, Zigbee
- Peripheral Interfaces: UART (Serial), I2C, SPI, USB,

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 /
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
Last week we walked through the Serial Console for Pine64 Ox64 BL808 64-bit
RISC-V Single-Board Computer. And we hit some illogical impossible problems
on NuttX for Ox64:
(1) Console Input is always empty. (Can’t enter any Console Commands)
(2) Interrupt Claim is forever 0. (Ox64 won’t tell us
Very cool!
Your graphics are very didact too!
It could be useful for the Milk-V port as well!
Best Regards,

Another great article!
One suggestion.

Nope they can’t, because the “U” User Permission is denied. Therefore

Amazing read Lup.. as
Memory Management Unit (MMU) is the hardware inside our Single-Board
Computer (SBC) that implements Memory Protection and Virtual Memory.
Sv39 is the RISC-V MMU inside the Pine64 Ox64 SBC, based on Bouffalo Lab
BL808 SoC.
In this article, we boot NuttX on Ox64 SBC to find out how Sv39 MMU works
wow! :-)
