What I was saying is that u-boot is able to boot (just start) other OSes, not that those will ever fully boot

Multiboot / bootmenu just change root (If I'm not mistaken).

Multiboot flashes kernels to the OneNAND every time you change your OS, which will eventually wear the flash.

I didnt completely understand what to do on this part:

combined image to N900 like a regular kernel.

You can use builder.py (below) to make the combined image.

Whats the goal..?
Or... how can i do it with Xterm?

Sooo... i got the default N900 kernel (zImage) here along with the u-boot.bin file.
I tried running the script, but it didnt work.
This is the error i get:

Code:

  File "builder.py", line 13
    elif len(kernel) > 0x1c0000
                              ^
SyntaxError: invalid syntax

Advice?

That won't work, you need to convert it into a uImage first.

The elif & else lines need a ":" at the end.

Any special options required in the zImage to uImage conversion? Or can you just run:

Code:

mkimage -A arm -O linux -T kernel -C none -d zImage uImage
