[Перевод] Операционная система в 1 000 строках кода (часть 2)

Продолжаем серию статей, посвящённую написанию собственной минималистичной ОС. В прошлой части мы познакомились со всеми вводными компонентами проекта и поставили общие цели. В этой же мы реализуем загрузку ядра, вывод строки Hello World!, механизм паники ядра, а также некоторые функции управления памятью и работы со строками. ▍ Навигация по вышедшим частям Часть 1 Часть 2 < — вы здесь.

Let's boot Apache #NuttX RTOS on the #RISCV Star64 #JH7110 SBC (and VisionFive 2) ... And experiment with the #OpenSBI Supervisor Binary Interface

Seems AMD with #openSIL could end up more open than RISC-V with their affinity to vintage hardware architecture #OpenSBI.

I found the fix to the #DRAM issue on the #JH7100 / #VisionFive1 - missed copying one stupid function call, whoopsies!

`disable_u74_memaxi_remap(1)` - that was it.

So, in other words: @oreboot now loads the #OpenSBI + U-Boot blob successfully and runs it from the cacheable RAM.

Next week I'll recap that and then get back to drafting #RustSBI, but the rest will be for next year.
