TI工程师你们好：
工作一年辛苦了，新春快乐。
在使用C6638ARM加载Linux系统时（版本为：K2_LINUX_03.10.10_14.07），linux系统加载地址为0x80000000，使用 mpmcl run dsp0-7可以正常加载dsp。
参考如下地址： http://processors.wiki.ti.com/index.php/MCSDK_UG_Chapter_Exploring
中的How to run Linux kernel from a different physical address than default (0x80000000) ?
将系统搬移到了0xa0000000,系统起来后是用CCS重新编译.out将out的内存地址分配在0x80000000-0x9fffffff;
修改系统启动后的/etc/mpm/mpm_config.json

运行到此处卡死了ctrl+c也停止无非结束
此处不明白是不是那里还需要配置没有处理导致核0会挂死在这里，此处run dsp的时候为什么为会报如下错误，如何查找根源。
