Read Only rootfs

[rstofer]

If I build a new rootfs following the directions from the Hello World tutorial exactly and then reflash the rootfs image, I wind up with a read-only file system in which I can not create a subdirectory to /mnt as in /mnt/thumb

If I reflash with the factory binary image, everything works fine.

My rootfs is 4321 blocks and the factory image has 4387 blocks.

One thing I have noticed about buildroot is that it uses headers from linux-2.6.22.1 while the kernel is actually built from lnux-2.5.22

Any thoughts?

Hi Rstofer,

Did you solve the read-only buildroot issue? I got the same result. If I load the factory rootfs it works fine. If I build my own, I end up with a read-only system.

Best Regards

I had the same problem and attempting to re-mount root as read/write gave me an error /proc/mounts was missing, so I added the following to the device table:

/proc d 777 0 0 - - - - -
/proc/mounts d 777 0 0 - - - - -
/proc/devices d 777 0 0 - - - - -

I added the following stuff for the MMC:

/dev/mmcblk0 b 777 0 0 179 0 - - -
/dev/mmcblk0p1 b 777 0 0 179 1 - - -
/mnt/mmc d 777 0 0 - - - - -

And now I can mount after startup using:

mount /dev/mmcblk0p1 /mnt/mmc

This is with kernel 2.6.29 although there is a bug in the current mach-tct_hammer.c file that you need to get a copy of from support.

Dear Sir,

I am a new user of and have encountered the same problem with the rootfs.

How did you solve the problem?

Thanks,

Paulin.
