原来是1G的 DDR更换为2G的之后，我更改了bootable\bootloader\uboot-imx\include\configs\mx6dl_sabresd.h中的 #define PHYS_SDRAM_1_SIZE (1u * 1024 * 1024 * 1024) ===> #define PHYS_SDRAM_1_SIZE (2u * 1024 * 1024 * 1024)。
然后第二步想要修改相对应的flash_header.S文件，但是没有找到mx6dl的，于是我找到bootable\bootloader\uboot-imx\board\freescale\mx6q_sabresd里面的flash_header.S文件，具体的内容我会贴出来。我修改后串口信息都不打印了。
调试串口信息如下：
