注* 板子型号是 TMDXEVM6678L，之前没有使用过gel文件初始化。
1.新建ccxml文件，选择XDS100V1-TMS32C6678
2.在Advanced窗口中，添加初始化脚本。初始化脚本来自..\..\simulation_keystone1\env\ccs\import\tisim_init_c6678_cx.gel
3.注释掉DDR初始化的程序后编译，进入DEBUG界面出现如图所示的红色错误，查看gel file窗口可以看到success状态
4.运行Hyperlink例程后，执行HyperLink_integrity_Test()函数，
Core1 LL2：HyperLink_Mem_Test(0x41800000, 0x0080000, 0x10000)执行顺利 HyperLink memory test passed at address 0x41800000

DDR：HyperLink_Mem_Test(0x48000000, 0x1000000, 0x10000)报错如下

对于HyperLink_integrity_Test，SL2和Core1 LL2都测试成功，只有DDR测试失败。
这是什么问题？
我找到问题了，是我使用了错误的gel文件。应使用..\..\emulation\boards\evmc6678l\gel\evmc6678l.gel这个文件就可初始化成功。但是我遇到了这样一个问题。
当运行到HyperLink_DSP_core_test()->MemCopyTest;
一直在重复执行这个函数 uiAddressd到LL2复制数据的函数

我使用一块板子进行测试 设置为loopback模式 先运行1核 再运行0核 发现程序进不了中断
程序运行到HyperLink_Interrupt_Test()- gpHyperLinkRegs->SW_INT= HW_EVENT_FOR_INT_TEST这个地方就没反应了
我在中断服务程序第一行写了puts语句，如果跳进中断，是会知道的。现在的情况就是中断没有进去
