请教关于DM8127在CCS上加载调试A8核问题

参考链接：http://processors.wiki.ti.com/index.php/Connecting_to_DSP_on_C6A8168,_DM8168,_DM8148
我载的dm814x相关的gel文件具体使用文件为附件中 IOExpansion_test_2.x.gel
操作步骤如下
1.通过串口停止uboot进一步加载

2.按照参考链接配置gel文件，launch Configuration 后connect A8核 在scripts中执行DM814X system Initialization->DM814x_System_Initialisation_GP_driver();

3.执行结果如下：

CortexA8: Trouble Writing Memory Block at 0x48100100 on Page 0 of Length 0x4: (Error -1065 @ 0x3D5A) Unable to access device memory. Verify that the memory address is in valid memory. If error persists, confirm configuration, power-cycle board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 5.1.73.0)
DM814X_System_Initialisation_GP_device() cannot be evaluated.
target access failed
at *((unsigned int *) 0x48100100)=(unsigned int) 0x01031FFF [IOExpansion_test_2.x.gel:708]

at DM814X_System_Initialisation_GP_device()
在0x48100100出寄存器操作失败，
对应的GEL文件中语句是：
WR_MEM_32(0x48100100, 0x01031FFF);
//WR_MEM_32(0x48100114, 0xC010E);
//WR_MEM_32(0x48100118, 0xF);
如果把“WR_MEM_32(0x48100100, 0x01031FFF);”注释掉，GEL脚步不能正常执行完毕。
0x48100100寄存器说明如下：

疑问：
1.0x48100100寄存器为何不能操作。
2.想要利用CCS对A8进行调试是否初始化：PSC、PLL、DDR、即可
3.因为缺乏linux基础和多核调试经验，想在CCS上进行A8和DSP的单核调试，直接添加至liunx体系下，不知该思路是否可行
