Re: nios2 no init found

Altera_Forum · ‎12-06-2006

Hi,

I can not make the kernel find the init process in the romfs filesystem.

With a 1c12 board I try this:

- kernel 2.6.11 at 0x0

- filesystem at 0x200000

The filesystem is working with another kernel, a kernel compiled under Windows.

the kernel is generated under Debian with the binary nios compile toochain.

My kernel stops when searching an init file in the filesystem (Kernel panic : no init found).

Hi Marc,

In the romfs built on Windows, all exec files have suffice ".exe" .

Maybe you can add "init=/sbin/init.exe" to kernel command string in kernel config.

hi hippo,

Thanks, but it does nothing more than my kernel panic .

Perhaps, it will be easier to build them over with uClinux-dist.
