[U-Boot-Users] Problem with the u-boot1.1.3 booting the uclinux from the jffs2 partition

[DeviPrasad Natesan]

Hi all,
I am presently using microblaze target and boot the uClinux using
u-boot (version 1.1.3) from the read-only root file system (mounted
read-only by the kernel command line parameter) from the directory
/boot. Everything works fine.

Just for debugging and testing few application, i mount the root as
read-write and after the uclinux kernel is up, i FTP'ed a big file
like the kernel or any utilities. I can run the ftp'ed application
properly and i can do a ftp get from the target and the image matches.
Everything seems fine until i reboot.

When the system is rebooted, the u-boot when it starts, cannot find
the new kernel and fails after getting the following error.

===========================================

To make sure that the MTD drivers works ok, i tested the whole
partition upgrade using netflash utility and it works perfectly fine
and the u-boot can boot the kernel.

Is this kinda behaviour as expected or in other words does the u-boot
expects the root-file sytem to be RO only. I am not sure is it becos
of the problem in the uclinux jffs2 or not.  I did include the
"CFG_JFFS2_SORT_FRAGMENTS" in the u-boot and checked and still got the
same problem.

Any pointers regarding this will be appreciated.

Thanx
