Currently, I have two partitions one for U- Boot and the rest for
application(kernel + application)
Total 16MB Flash
1MB U Boot
15MB JFFS2 Application
The U boot loads the kernel from jffs2 using fsload and the system works
fine. Sometimes, during software upgrade, the problem comes when jffs2 is
almost full, the files could not be deleted to freeup space because of jffs2
limitation. The entire partition needs to be reflashed which is not a
practical solution .
Is there any better way to recover from this failure situation where we can
boot a minimum kernel and can format the jffs2 partition and copy the
application image?

I have an requirement to have three partitions in the Flash
1. U Boot
2. JFFS2(GoldenImage) (Mininum Kernel Image )
3. JFFS2(Application Image) (Kernel + Application)
The idea of Golden image is to use this partition to boot in case the
application image fails after software upgrade due to corruption of the
filesystem in this partition if any during upgrade. When the system is
up
with Golden image, partition 3 can be updated.
Is this method feasible. Kindly let me know if you have better ideas or
suggestions?
Yes, this is possible (actually, it's trivial).
Without knowing your exact requirements and restrictions it's
difficult to recommend better ideas...
Best regards,
