我们在合众达（Seed）的DVS8168开发板（与TI的evm816x很相似）基础上裁剪了一块8168板子，板子情况如下：
去掉了SATA接口、SERDES CLOSCKS、PCIe接口，
CPU采用的是TMS320DM8168CCYG，
DDR由8片K4B2G0846D（共2GB）换成了4片MT41K128M16JT（共1GB），DDR已用DM816x_C6A816x_AM389x_EMIF4_Register_Settings重新设置了寄存器参数，并且在u-
boot中也做了相应修改。
硬件部分在CCS下用evm816x_BSL做了测试，都能通过。
我们采用了NANDFLASH启动方式，用的是Seed提供的SDK包（DVRRDK_02.00.00.23）中的u-boot和内核程序，这部分程序是在TI的linux-psp-dvr-04.00.01.13上做了一些修改。
现在的问题是u-boot能正常启动，但加载Linux内核时就卡在Starting kernel ...动不了了。以下是u-boot的启动信息和加载内核时的参数设置。应该是用的UART0
，波特率也是对的。
我们刚开始接触Linux内核，请问这个问题可能是由什么造成的？应该如何入手调试解决？会不会是由于DDR由2GB换成了1GB引起的？u-boot下为什么显示DRAM: 2
GiB？我们应该修改哪部分的代码？
