CS0首地址从0x0000 0000开始，每个cs空间大小是可以配置的，所以后面CSx的首地址要根据每个空间大小来决定。 请查看TRM 2.2 L3_MAIN Memory Map GPMC space: Eight independent GPMC chip selects (CS0 to CS7) are available in the first quarter (Q0) of the addressing space to access NOR/NAND flash and SRAM. The chip selects have a programmable start address and programmable size (up to 128MiB) in a total memory space of (Q0) 1GiB, but limited now to 512MiB.
