[Article] RISC-V Ox64 BL808 SBC: Starting Apache NuttX Real-Time Operating System
#1
Last week we booted Linux on the Pine64 Ox64 64-bit RISC-V SBC, powered by Bouffalo Lab BL808 SoC. And we wondered if a tiny 64-bit Real-Time Operating System (RTOS) like Apache NuttX RTOS might run more efficiently on Ox64. (With only 64 MB of RAM)

Let’s make it happen! In this article we...
(1) Begin with NuttX for Star64 JH7110 RISC-V SBC
(2) Boot it unmodified (!) on our Ox64 BL808 RISC-V SBC
(3) Add Debug Logs in RISC-V Assembly
(4) Tweak the NuttX UART Driver to print on Ox64
(5) Fix the Platform-Level Interrupt Controller
(6) Track down why RISC-V Exceptions aren’t dumped correctly
(7) And plan for the upcoming Initial RAM Disk
