Currently we have a system (mpc8360) with multiple filesystems in flash
to control the size of certain directories.

We startup the flash driver as follows:

  devf-8360 -s 0xfe000000,32M,,,128k,2,1

Flash starts at 0xFE000000 and is 32M.

 

I run into a problem when if some filesystems were moved around or
resized because the flash driver will finds and mount stale filesystems.
I can erase all of flash when these types of filesystem layout changes
are made, but I would like to avoid it because it's time consuming.

 

Does devf-* support mounting filesystems from a specific range in flash?

 

I tried 

# devf-8360 -s 0xff400000,4M,,,128k,2,1

To get the "Coredumps" filesystem from flash range 20M - 24M

 

It mounts it ok, but something doesn't seem right when I type mount:

 

# mount

/dev/fs0p7 on /coredumps type flash

/dev/fs0p6 on /coredumps type flash

/dev/fs0p5 on /coredumps type flash

/dev/fs0p4 on /coredumps type flash

/dev/fs0p3 on /coredumps type flash

/dev/fs0p2 on /coredumps type flash

/dev/fs0p1 on /coredumps type flash

/dev/fs0p0 on /coredumps type flash

 

Is this a bug in my flash driver or is it not a supported way to mount a
filesystem.

 

Verbose output below.

 

Thanks,

Bernard
