When I examining QorIQ SDK 2.0 document, I have faced with a system memory map which the boot loader maps in T1023(Section 188.8.131.52). In the attachment, you can see the nand flash is mapped just 64 KB size. However, when we look over the T1023 RDB product page, 512 MB nand flash is used on the board. Why 512 MB nand flash is used if its just 64 KB can be mapped? Or, is there an other issue that I know?
