Uboot flash problem on uncustom P2020RDB-PC

Hi,

 

We got a problem on U-boot flash.

We changed the NOR Flash on P2020RDB-PC from 16MB(S29GL128P) to 64MB(S29GL512P).

And we got problem on uboot flash.

I know how to flash uboot using Codewarrior on custom board with 16MB NOR Flash.

What should we modify in process of uboot flash to 16MB NOR that we can flash uboot to 64MB NOR?

Thanks.

 

Best Regards,

Hu

Yes, you should modify the TLB and LAW to configure your new NOR mapping.

You can map any peripheral (DDR, NOR, NAND, PCI and so on) to any addresses using a different memory range in TLB, LAW and CS (chip select). So, in your case you should modified the initialization file, to address your changes. Also, to program uboot in new NOR, in CodeWarrior Flash Programmer you should add S29GL512P into Flash Devices view.
