Hi Yuan,

I think DDR is not configured properly on your setup. After loading the gel file please check DDR configuration register on memory browser.

Thanks,

Hi Yuan,

This function initializes the device registers with the appropriate values provided through the HwSetup data structure.

After this function DDR2 registers are configured according to the hardware setup parameters.

For more information refer section "4 DDR2 Memory Controller Registers" on C6472 DDR2 Memory Controller guide.
