@icenowy yep working on NuttX can be challenging because we need to support STM32, ESP32, PineCone, PinePhone, Star64, Ox64, ... :-)

Here's how we Blink an LED with #NimLang on Apache #NuttX RTOS

Article: https://lupyuen.codeberg.page/articles/nim.html#blink-an-led

@icenowy Probably because NuttX supports many platforms? x86, RISC-V, MIPS, SPARC, Xtensa, etc

https://nuttx.apache.org/docs/latest/platforms/index.html

@icenowy I think it's because NuttX also supports microcontrollers with Memory Protection Unit (but don't have Memory Mgmt Unit) ... So NuttX will relocate each ELF App to a Memory Region that's allocated to the app

Noted. You can stop spamming me now 😂
