怎样编写GEL文件驱动DM8148中的c674x



在CCS4上连接上cortexA8,后下载ccs4自带的各类文件(DM814x_EVM_512MB_v2.0.gel)

连接脚本文件,按如下操作:Scripts -> Centaurus System Initialization -> run DM814_system_Initialisation_TEXT_device

但是却在PRCM for OCMCRAM0/1 Initialization in Progress时停住了

console窗口显示如下:

gel文件见附件

这个gel是安装ccs4带的,需要再对寄存器配置修改,才能将dsp启动起来?

还是dsp核有问题?

多谢大家指教
