Zahir Wang：

用一块板子 同时用0核与1核跑STK的例程没有任何修改 但是遇到了DDR初始化失败的问题
请问这是什么情况？应该怎么解决？

,

Nancy Wang：

是自制板吗？leveling失败建议根据自制板的硬件情况重新计算确认一下DDR参数部分,参考Keystone I DDR3 Initialization：
www.ti.com.cn/…/sprabl2e.pdf

,

Zahir Wang：

板子型号是 TMDXEVM6678L

,

Nancy Wang：

将STK例程中KeyStone_DDR_init 初始化DDR的函数注释，直接使用GEL文件初始化，再执行程序试一下。

,

Zahir Wang：

我想再问下怎么使用gel文件进行初始化？

,

Nancy Wang：

一般在创建.ccxml文件时，target configuration选项中会提示导入初始化脚本，在对应的选项中选择GEL文件就可以了。

,

Zahir Wang：

你好 我导出初始化脚本后 consle窗口报出这个错误

Error while executing StartUp( 6, 2, 0, 1631 ): Could not write 0x00800000: target is not connected at *((int *) 0x00800000)=0x0001E000 [tisim_init_c6678_cx.gel:40] at load_idle_instr_at_ISTP() [tisim_init_c6678_cx.gel:19] at StartUp(6, 2, 0, 1631)

,

Nancy Wang：

请大概描述一下您的操作步骤以及使用的GEL文件。是自制板吗？之前没有通过GEL文件初始化过板子吗？

,

Zahir Wang：

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，

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？

,

Zahir Wang：

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

,

Nancy Wang：

单步调试看一下，代码改过吗？

,

Zahir Wang：

代码没有修改过，单步调试也不行。

这三行程序都是同一个函数，第一行的是从LL2复制数据到uiAddress

而第二行这个是从uiAddress到LL2

同样的函数，只是把参数src地址和dst地址掉了个头，就出现了这样的情况。奇怪…

,

Nancy Wang：

不清楚了，再重新导入编译试一下看看，代码没问题。

,

Zahir Wang：

CCS6重新导入编译没进行尝试，但是同样的工程复制到CCS10就可以正常跑程序。

,

Zahir Wang：

我想问下，这个手动触发什么意思？我需要在板子上拨动拨码开关吗还是？

,

Nancy Wang：

应该是指手动写SW_INT寄存器，不需要操作拨码开关。

/*manually trigger the hardware event, which will generate interrupt packet to remote side*/ gpHyperLinkRegs->SW_INT= HW_EVENT_FOR_INT_TEST;

建议对照hyperlink手册理解。

,

Zahir Wang：

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

,

Nancy Wang：

Zahir Wang 说：先运行1核 再运行0核

您是对两个核分别进行loopback吗？请单独测试一下core0 loopback是否有问题。

,

Zahir Wang：

我手上有两套K1_STK的程序 之前一直在拿第一套跑 出现了这些问题 今天我拿第二套程序跑了跑 没有问题 debug信息跟STK_user guide一样

所以我判断是第一套程序可能是之前调试修改过后的程序。我想再问下 K1_STK的程序在官网上哪里可以下载到？虽然我有这个程序，但是我还是想知道具体的下载地址 谢谢
