Re: [microblaze-uclinux] EXT2 error / read only file system

["Bruno Herrera" <bruherrera@xxxxxxxxx>]

Hi John, 

I'm using the uClinux-dist that I get in CVS some time ago. Is there a way to succeed mounting a EXT2 filesystem? Is something missing in my linux configuration? 

I will check the permissions and then I post it here! 

Best Regards, 
Bruno Herrera

At boot, the kernel attempts to mount the root device with all known
filesystems.  You have compiled ext2 and romfs support into your kernel,
so both filesystems "get a go" at mounting the root device.  Since your
root dev points to a memory-based romfs filesystem, ext2 fails, but
romfs succeeeds.  This is not an error, it's just how it's designed.

On your development machine, have a look in petalinux-dist/romfs/etc -
what are the permissions on the rc.sysinit file?

Are you using a standard petalinux install, or uClinux-dist?

John
