Linux - a question about linux fs in flash

Hello, does anyone know if the Microtronix ROMfs is cached in RAM upon bootup? I mean does the fs take up the same amount of RAM as it occupies in flash? I have a custom board with a 2MB flash ...

Hi Goon,

It is the kernel, not romfs, that eating up your memory. The 813K + 122K is the static size of your kernel (code + data + bss). But the kernel dynamically allocates a lot of stuff during the booting, thus eating up your remaining 1M RAM.

Regards,
