flash programming 256M change 512M

[威杨]

Hello

   I use code warrior10.4.0, i use it download uboot,i use it base mpc8309SOM,previous nand is NAND02GGW-eLBC,refer to 8309SOM_NAND.xml,but i use MT29F4G08ABADA-eLBC,no .xml file,i modify the 8309SOM_NAND.xml,but it not working,who can give me some advises.

Thanks.

Hello wei yang,

You need to modify CodeWarrior initialization file to make it suitable for your new flash device.

Please modify the following sections in the file C:\Freescale\CW_PA_v10.4.0\PA\PA_Support\Initialization_Files\83xx8309SOM_init_core.tcl.

1. Please modify LAW(Local Access Windows ) for NOR Flash(begging address and LAW size).

2. Please modify BR0 and OR0 registers configuration in the section "Local Bus Interface (LBIU) Configuration", please refer to MPC8309 reference manual for how to configure these two registers.

3. If you use different DDR on your target than MPC8309SOM, please also modify DDR2 Controller configuration section.

Have a great day,
Yiping

Thanks for your answer, i think should modify C:\Freescale\CW_PA_v10.4.0\PA\bin\plugins\support\TargetTask\Flash_Programmer\83xx\8309SOM_NAND.xml.i only see about flash size,i modify it ,name 8309SOM_NAND512.xml.could you tell me modify it like this wrong or right ?

You didn't specify the correct Flash Device Name, as you mentioned previously, you use MT29F4G08ABADA-eLBC.

If your problem remains, please provide the console log of flash programmer and CW initialization file.

Thanks,

Yiping
