[Balaji Sivakumar, ERS, HCLTech]

Hi Dirk,

Thanks for your resonse. I have just added into this thread beacuse both are spansion flash.

my responses to your query:
1.am using u-boot_2099-08 U-boot. it came with imx6q saberlite board.
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.
3. CONFIG_SYS_FLASH_BASE is WEIM_CSO_BASE_ADDR(0x08000000)

I will attch the Config file soon.

Thanks ,
ShivBalaji

Just to be sure: Do you use the mainline U-Boot (u-boot.imx) or the
old Freescale one?

This thread talks about S29GL512P. You talk about S29GL01G?

Can you send us your flash/CFI configuration from the config file?

Which CONFIG_SYS_FLASH_BASE do you use?

Best regards

Dirk
