Hi Wolf,

Thanks for your responses.

Board is same like IMX6q sabelite board, only difference is we have Spansion Nor Flash S29GL01GS in our board, which is connected via WEIM Bus Chip slect 0 and Data bus is 16 bit(D16-D31).

I have weim bus io mux config and cs0 initialization in mx6q_saberlite_board.c file and also i have added the Flash base address as WEIM_CS0_BASE_ADDR, Flash width as FLASH_CFI_16 bit,Max sector details(1024), Max Bank(1) etc in the config file.

You have mentioned memory map in your mail, is that what i mentioned above in the config file.

Thanks , ShivBalaji ________________________________________ From: Wolfgang Denk [wd@denx.de] Sent: Sunday, March 11, 2012 12:40 AM To: Balaji Sivakumar, ERS, HCLTech Cc: u-boot@lists.denx.de Subject: Re: [U-Boot] Does U-boot supports Spansion S29GL512P NOR Flash?

Dear Balaji Sivakumar,

In message loom.20120310T113930-255@post.gmane.org you wrote:

I am Balaji. am using IMX6 base custom board. In my board am using S29GL01G NOR Flash to srore u-boot and kernel. I understand from the data sheet this NOR Flash is CFI based on. So i have added Configurations for CFI Flash driver.

Thi sis of course only part of the configuration that is needed.

Currently am loading the U-boot into DDR3 and able to excute U-boot test commands. When i put flinfo , am getting "missing or unknow flash type" and while loading the u-boot it is printing as " Unknown flash on BANK 1 - Size - 0MB". So am not sure what am missing here or i have to add anything extra in teh config file. Please request you to check and provide your suggestion.

For example, you must also set up the memory controller and memory map as needed for your board.

Best regards,

Wolfgang Denk
