In this article we’ll boot a tiny bit of Apache NuttX RTOS on the Star64 64-bit RISC-V Single-Board Computer. (Based on StarFive JH7110 SoC)

(1) Migrate NuttX RTOS from QEMU Emulator to Star64
(2) Print to the Serial Console in RISC-V Assembly
(3) Trick U-Boot Bootloader into thinking we’re Linux
(4) Downgrade from Machine to Supervisor Privilege Level
(5) Helped by OpenSBI Supervisor Interface
