Hi Derk, Thanks for your response. I will download the latest one and check it. Currently am booting the u-boot from DDR3 only and checking the flash information using "flinfo" command, but that itself fails for me. I have not programmed the u-boot into NOR FLASH yet. To detect ,print flash information and its read, write, erase etc, do I have to add anything extra in the board file or flash_header.s file. Am little confused whether i miss any configuration for FLASH, because we are able to read the MAN ID and Device ID through diagnostic Software. But through U-boot fails. Please find my flash configuration details. #define CONFIG_SYS_FLASH_BASE CS0_BASE_ADDR #define CONFIG_SYS_MAX_FLASH_BANKS 1 /* max number of memory banks */ #define CONFIG_SYS_MAX_FLASH_SECT 1024/* max number of sectors on one chip */ /* Monitor at beginning of flash */ #define CONFIG_SYS_MONITOR_BASE CONFIG_SYS_FLASH_BASE #define CONFIG_SYS_MONITOR_LEN (512 * 1024) /*----------------------------------------------------------------------- * CFI FLASH driver setup */ #define CONFIG_SYS_FLASH_CFI 1/* Flash memory is CFI compliant */ #define CONFIG_FLASH_CFI_DRIVER 1/* Use drivers/cfi_flash.c */ /* A non-standard buffered write algorithm */ #define CONFIG_SYS_FLASH_USE_BUFFER_WRITE 1/* Use buffered writes (~10x faster) */ #define CONFIG_SYS_FLASH_PROTECTION 1/* Use hardware sector protection * Please request you to provide your suggestion.

This is the 'old' U-Boot from Freescale which is modified heavily by Freescale. Please ask the Freescale support for this. Please try the recent mainline U-Boot, e.g. http://git.denx.de/?p=u-boot/u-boot-imx.git;a=summary > 2.NOR Flash is connected to WEIM Bus Chip select 0 and 16 bit Data > bus(D16:D31), I have done Weim Bus Mux Config in the Mx6q_saberlite_board .c > and also Chip select 0 initailization. Hmm, I'm not totally sure, but if you boot from NOR, the correct mux should already be done by the boot ROM code. > 3. CONFIG_SYS_FLASH_BASE is WEIM_CSO_BASE_ADDR(0x08000000) This looks correct.
