Hi,
I have few basic doubt on UBIFS/UBI.

At present i am seeing some 64 bytes read request coming while doing
the "ubiattach" on one of the MTD partition.

What's the typical read/write length request that come's from the UBIFS?
In a normal scenario read/write requests to flash would be multiple of
flash page size? or it could be of any size?

Why is this a problem?

It depends of what is being read. Sometimes these are few bytes (reading
LPT or a direntry), sometimes 1-2 pages (reading file data), sometimes
whole eraseblock (GC-ing).

Any size.
