[Article] NuttX on Ox64 BL808 RISC-V SBC: NuttX Apps and Initial RAM Disk

2023-11-25 Thread Lee, Lup Yuen
In Asia the wise folks say: “One can hide on a certain day but cannot hide
for a long time / 躲过初一,躲不过十五”

In other words: “Transformers? More than meets the eye!”

In this article, we go behind the shadow puppetry (wayang kulit) and
deceptive simplicity of NuttX Applications inside Apache NuttX RTOS for
Pine64 Ox64 BL808 64-bit RISC-V SBC:

(1) What’s inside the simplest NuttX App
(2) How NuttX Apps make RISC-V System Calls to NuttX Kernel
(3) Virtual Memory for NuttX Apps
(4) Loading of ELF Executables by NuttX Kernel
(5) Bundling of NuttX Apps into the Initial RAM Disk
(6) How we found the right spot to park our Initial RAM Disk
