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:

Zhihua Zhang:

再有,现在这个版本bootargs参数传递console应该是console=ttyS1,115200n8还是console=ttyO1,115200n8?

非常感谢,是这样么?

回复 Shine:

这个版本配置和文档描述好像不一致了,是否是这样配置?
