Hi,
We are using u-Boot in Lite5200B with DDR. We compiled the u-Boot with “ icecube_5200_DDR_LOWBOOT_config” option and flashed the image in to flash at * 0xFF800000 * .
The problem we are facing is,
The image is *booting* only if we flash the image in *both (0xFF800000 and 0xFF000000) places*. The reset vector for the two configurations (icecube_5200_LOWBOOT & icecube_5200_DDR_LOWBOOT) are same.
We have tried by writing different images in these locations and found that the booted image is the one which is flashed in 0xFF800000. But if erase the image at 0xFF000000, it is not booting.
The Lite5200B has two banks of 16Mbtes flash, so if you flashed U-Boot in the 0xFF800000 you are putting it in the meddle of the flash, nor in theLOWBOOT location, nor in the HIGH boot location. When you flash a new U-Boot in the 0xFF000000 the system starts from this location but I think there is a jump to the U-Boot flashed in the 0xFF800000 because your TEXT_BASE ( the address reference for the linker) in U-Boot is 0xFF800000. The correct address for the LOWBOOT in the Lite5200B is 0xFF000000.
