any idea of # of write cycles of NAND in micro2440

Hi,

Anyone has any idea of the maximum number of write cycles of NAND used in
micro2440?

TIA

Dear Vikas,

 have you worked on NAND Flash?

Dear Lalitha,

I hope I am working on NAND flash as NAND flash is used in my board.  From
the manuals I found that it has 1M write cycles max.  I also hope that you
know bad blocks are developed in NAND flash when you keep writing it.  The
similar types of chips are in SSDs.

So i resolved this by putting my root file system on SD Card. Now i need
not worry about write cycles in my NAND flash.

Dear Lalitha,

I agree that the limitation of write cycles applies to SD CARD too.  But
replacing SD CARD after failure is much easier and cheap.

Atcually I am trying put my application in NAND Flash but the application
hangs up in the middle itself but same application runs fully in SDRAM why
is this difference? if u know plz. highlight on this

Lalitha,

You have to tell me details of your application.  Which OS you are using? 
How that application is compiled?  which boot loader and kernel you are
using?

See I have compiled complete application using ADS1.2 and its size is about
1.9MB and I am using supervivi boot loader which come along with the kit

This should work without any problem.  As replied in other post, boot from
NOR and then download and run.  That will download the application to NAND
and run from there.

the same application runs fine in SDRAM but does not work in NAND flash
