(0x02000000) System memory base address (0x1E000000) System memory size (0x02000000) kernel base address (0x400000) u-boot text base address offset to memory base address Coherency The DMA Proxy driver by default uses coherent memory which is non-cached in a s/w coherent system. Save the configuration settings and exit the Configuration wizard. These will be used when creating boot images. 修改DTS (另外) memory { device_type = "memory"; reg= <0x0 0x0 0x0 0x6ff00000>, <0x00000008 0x00000000 0x00000001 0x80000000>; }; So the base_adress for PetaLinux should be 0x2000000.
