[Article] NuttX on Star64 JH7110: OpenSBI (Supervisor Binary Interface)

["Lee, Lup Yuen" <lu...@appkaki.com>]

Bare Metal Programming on a RISC-V SBC (Single-Board Computer) sounds
difficult. Thankfully we can get help from the OpenSBI Supervisor Binary
Interface! (A little like BIOS, but for RISC-V)

In this article, we boot NuttX on Star64 JH7110 RISC-V SBC (and
VisionFive2) to experiment with OpenSBI:

(1) Print to the Serial Console
(2) Set a System Timer
(3) Query the RISC-V CPUs
(4) Fetch the System Information
(5) And Shutdown / Reboot our SBC

Hi Lup,

Great work, you are creating a huge set of documentation, not only
about NuttX but also about RISC-V, OpenSBI and JH7110 processor!

Kudos!!!

BR,

Alan
