What flash file system on uCLinux 2.0.38?

What flash file system on uCLinux 2.0.38?

[Tim Gardner]

Hi,

I'm stuck using uCLinux (based on 2.0.38) on an ARM7 platform. I have 2 CFI
compliant flash parts (AM29DL323D), and will soon have to support equivalent
sized Intel Strataflash.

The JFFS that comes with uCLinux 2.0.38 is hopelessly based on flash.c which
only support a few parts. I've backported the latest MTD from CVS, and all
seems to work using CFI and cstm_cfi_jedec.c. However, the new JFFS is
based on 2.2.0 VFS inode and dentry cache stuff. Way too much work to backport.

Does anyone have a suggestion for a flash filesystem that I might use? Using a
regular file system on the flash translation layer is not an option since this
is not a PCMCIA platform (patent issues I guess).

Correct, unless you live (and only want to ship your product) in the Free 
World.

It shouldn't be too difficult to merge the latest JFFS code back into 2.0. 
You're welcome to provide 'inode-v20.c' if you want, and I'll even try not 
to break it later :)
