Hi Titusrathinaraj ,

    I have followed the 1st step Boot From SD Card ;

    written Each Block As Mention ;

  apart from that tried to Load Back up also;

SPL ,SPL backup.1 SPL backup.2,SPL backup.3,u-boot-img

"""Change the boot jumper settings to NAND flash

      Reset the board & check whether the board is booting u-boot from NAND flash on console."""""

here  I didnt find any thing nothing got display ; 

Is there Some hardware pin need to be enable to Read the NAND Flash in Hardware That must it missing

I am Attaching my NAND Connection pls Have a look!!

Out of Which R31 and R32 is not connected Is it required ??

 

Result on Oscilloscope are :-

--When Booting from SD Card  Change on PIN RE '  pulled Down and the n got Pulled Up;

-- While nand write WE ' pin is getting Low ;

-- On I/O pin there is pulses generated  while nand writing;

Is R32 and R31 are reqired ??
