关于最新版本SDK在OMAPL138上无法启动的问题 “Starting kernel ...” 急！急！急！

大家好，我手上的板子是很早之前做的OMAPL138，原来是Linux-2.6,最近准备升级Linux，在官网下载了ti-processor-sdk-linux-omapl138-lcdk-04.00.00.04-Linux-x86-Install.bin进行安装，安装完成后对uboot进行了配置，uboot可以正常启动，但是引导内核时停在了“Starting kernel ...”，板子使用的是UART1作为调试口，NAND Flash，编译过程如下：

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- distclean

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- tisdk_omapl138-lcdk_defconfig

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- zImage

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- da850-lcdk.dtb

然后使用tftp将zImage和dtb文件下载到板子，使用bootz引导时停在“Starting kernel ...”没反应了！

是我编译得不对？还是需要修改其他配置？有没有什么办法能跟踪一下卡在哪里了？

过程如下：
