Subject: Q: Filesystem choice..

Message-ID: <m3u12jr8y4.fsf@maxwell.lnxi.com> (raw)
Currently I am examining the possibility of using a filesystem with
LinuxBIOS so that I may store parameters and kernels in the flash in a
more flexible manner.
The current flash chips I am working with are NOR flash from 512KiB to
4MiB. And they generally have a 64KiB erase size.
I have two flash blocks that are reserved for XIP code (the hw
initialization firmware) and the rest can be used for the filesystem.
So in the worst case I have 6 flash blocks to play with.
The old papers on jffs2 would make it unacceptable as it reserves
5 erase blocks. And I don't know if yaffs or yaffs2 is any better.
In addition boot time is important so it would be ideal if I did not
to read every byte of the ROM chip to initialize the filesystem.
Is there a filesystem that only reserves one erase block?
Does it look like I need to write my own solution?
Eric
