You need to configure the registry setting and GPMC configurations

Dear suhas,

Please use the A8 1.02 BSP

You need to add the registry settings for your nand flash in the new chip select in \SRC\DRIVERS\BLOCK\NAND\nand.reg under section [HKEY_LOCAL_MACHINE\Drivers\BuiltIn\MSFlash],

Configure the supported nands in SRC\BSP_COMMON\BSPCFG\bspcfg.c

GPMC configurations in \SRC\INC\bsp_def.h and \SRC\BOOTLOADER\XLDR\platform.c

Configure GPMC pads in \SRC\INC\bsp_padcfg.h

hi Suhas,

Please check the section 26.4.6 Fast External Booting,

It says boot rom will support only CS0 for booting, you can use other chips in other chipselects but CS0 is required for booting
