How to set drive strength of NAND device during bootup for custom i.MX28 board?

Hi,

 

I have been testing to boot up from raw nand device for custom i.MX28 board.

It looks OK but I want to try to change the drive strength of nand, just in case.

I checked manuals but I couldn't find such boot config pin(LCD_DATA*/LCD_RS) or OTP fuses.

 

How can I add user code and data to the (probably) FCB?

Is there any sample code?

 

Actually I used MT29F8G08. Please see p44 of datasheet.

It seems gpmi bus set command=EFh,address=10h/80h for choosing SET FEATURES and output drive strength.

 

Can anyone help me?
