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 - Prasad
