more bad block in my nand flash.......Scanning device for bad blocks Bad eraseblock 1 at 0x000000020000

Hi Everyone,

I m using dm355 evm kit and my ubl version is 1.50 and my u-boot version is 1.3.4,
now i m getting more bad blocks in nand flash while scanning bad blocks when kernel extract starts
PFA of my log and do the needful,



UBL: detected valid U-Boot magic number
