Hi Everyone,

I have seen this question come up before on the list, but I haven't really
seen a satisfactory response so I thought I would post it again...
I understand how to put a (java) program into flash but I would also like to
store other supporting files there (such as a web page, an applet, small
images, system parameters file).  What I would like to do is be able to
clear the RAM at reboot and then rebuild/restore the file system from flash.
Is this an easy thing to do?  I have not come across any java routines to
achieve this although I feel that support for this should be provided.
Also I would like to be able to store parameters in flash that can be
recovered when the system is rebooted.  These parameters would only be
stored perhaps once at the beginning of the life of the product.
The reasons for doing the above are:  
1.  Hopefully our product will be used for 10+ years and during that time
may be cycled on and off a few times.  If the RAM battery backup fails
(likely after 10+ years) then if everything is restored from flash it
doesn't really matter.
2.  The system should boot up quicker if we don't have to sort out the RAM
when we reboot (i.e. just clear it and restore everything from flash).
Dallas - are there any plans to add java support for doing things with the
flash? I have seen a number of people asking for similar things to the
above.

Thank you,
