K2GICE下载代码出现问题

Other Parts Discussed in Thread: 66AK2G12

CCS是7.4版本，调试器是XDS220U,把66AK2G12的一个官方软件包K1_STK_v1.1里面的一个GPIO演示工程编译通过，然后用调试器下载到K2GICE板子上，结果CCS7.4的Console上一直不停的滚动   memory protection execption cause by local access at  0x80F4A0,看样子程序是对这个存储区域的写入导致CPU保护了，程序就没法往下运行了。

首先，这个K1_STK_v1.1软件包里的这个代码我没做任何修改，就写入到K2GICE的板子上去了，不知道这样做是否适合，然后K2GICE这个板子本来最开始上面的CPU是66AK2G02，但我从TI那边买过来后发现CPU是66AK2G12，两者主频差了很多。

K2GICE板子上默认的BOOT模式是24MHZ下由SD卡启动，这个启动模式我没有动过，然后出现这个存储器异常保护的情况后，我试着把BOOT模式用拨码开关改成24MHZ下的调试器引导模式，情况还是一样的.

综合以上情况，不知道那个存储器异常保护的问题该怎么解决，希望TI的大神能帮帮忙

    K2GICE属于keystone2，请测试k2 stk的例程。

    你好，用了K2_STK_DSP_v1.1.zip这个参考例程包里面的几个代码，效果还是一样的，memory protection execption cause by local access at，只是地址有些变化

    有没有单步调试看看，程序到哪里会报错。

    不行，刚一点运行，面板那里就一直报错，然后程序自动跳转到一个汇编源文件那里，指示程序出错

    再核对一下步骤：
    The test program can be run on all KeyStone 2 EVM.
    The steps to run the test cases on EVM board are:
    1. extract (or install) the package, and switch CCS workspace to the extracted folder (or installation folder)
    2. import the projects to CCS6.1 or higher;
    3. build the projects. You may need to change the CSL including path, by default the project use CSL header files in: C:\ti\pdk_keystone2_3_01_01_04\packages\ti\csl
    4. Set the boot mode of the device on EVM to no boot.
    5. load the program to core 0 of a DSP.
    6. run the core, then, you should see output in console window.
    Refer to appendix of this document to see the typical test output.

    0x80F4A0是预留内存空间，一般都不会去访问这段地址空间。

    psc_regs= (K2_ARM_LPSC_Regs *)&gpARM_regs->PD_CPU0_PTCMD;

    Description Resource Path Location Type
    #20 identifier "gpARM_regs" is undefined K2_common.c /I2C/src line 1110 C/C++ Problem
    现在是这么个情况，要报错

    我直接把那条语句屏蔽了能编译通过，但运行还要报错，不过不是地址保护报错了，看信息像是就是时钟那块的问题，应该和这条语句有关系

    KeyStone.cmd
    66AK2Gxx_C66.cmd
    现在就有两个CMD文件，选第一个的话，就是那个时钟报错，选第二个的话，就还是地址保护报错，但地址说是在0x02的位置，和先前保护的位置差异很大

    哦，对了，忘了补充了，这个K2GICE板子，本来应该是66AK2G02的CPU，但我买来拿到手后发现是66AK2G12，两个CPU主频不一样，会不会和这个有关系啊，时钟配置那块我也没动过

    用这个文件夹下的GEL文件试试。
    C:\ti\ccsv8\ccs_base\emulation\boards\icek2g
    应该不需要修改程序的，要修改的步骤都会在doc文档里面提到，也就是上面我贴出来的步骤。

    GEL文件一直都是CCS7目录下的，没动过，每次开始进调试的时候，面板上第一句似乎就有问题
    [C66xx] JTAG ID= 0x8bb0602f. This is a unknown device, version variant = 8，不能正确识别器件，我看了软件包的WORD文档，调试的时候面板上第一句都是正确识别到了器件的，我这一直是未知器件

    刚刚我把工程的芯片选择为66AK2G02，而不是K2GICE，虽然还是报未知器件，但可以运行了

    但这样做肯定不妥，毕竟板子上芯片是66AK2G12，但是芯片选择栏里面，居然没有66AK2G12的选项，只有2G01，2G02，这两个，其余的都是K2L和K2H系列，当初安装CCS的时候，K2G芯片库我是一并安装了的，K2G01，K2G02都有了，为啥会没有K2G12，好奇怪
