I am forced to use this kernel (2.4.x) by limitation of my target  
board, especially the only 2MB of flash.
I build successfully a 2.6.x image, but without my applications was  
already near the limit of memory.

The mtd-utils version is: in file mtd-utils.spec
      .....
      Version: 1.0
      Release: 1
      .....

  The flash_erase version:
      .....
      # flash_erase --version
      flash_erase version 2
      .....

I dont have nanddump and nandwrite utilities. My flash is NOR type  
(am29lv160db).
But in source files:
      nanddump.c: "$Revision: 1.29 $"
      nandwrite.c: "$Revision: 1.32 $"

I think the mtd-utils version is the same to kernel 2.4.x and 2.6.x in  
my distro source.
This can not generate some compatibility issues?

In the past, mtd-utils have the utilities erase and erase_all. I think  
that utilities work with my kernel, is that possible?
You know what version of mtd-utils are available (erase and erase_all)?
I can try this version.

Best Regards.
