TMS320C6678评估板DDR3读写错误

user4720228

使用K1_STK_v1.1文件中的Memory_Test例程测试DDR3时写入和读出数据不一样

软件为CCSV9，库文件为pdk_C6678_1_1_2_6

宏定义只开启了EXTERNAL_MEM_TEST和TEST_BY_DSP_CORE

DDR3 bus test测试通过，地址0x80000000到0x80000400也测试通过，再后面的测试项读写都通不过

调试信息如下

    ti-processor-sdk-rtos-c667x\pdk_c667x\packages\ti\platform\evmc6678l\gel中有一段简单的测试DDR读写的程序，您可以再次测试一下是否能够测试通过。
    @brief Simple DDR3 test
    * @details
    * This function performs a simple DDR3 test for a memory range
    * specified below and returns -1 for failure and 0 for success.

    把地址范围改一下测试看看有没有问题，能通过的话DDR读写就没有问题。
    GEL里面只是测试了0x80000000~0x80000400 。

    测了一下的确可以

    为什么K1_STK_v1.1中的程序不行呢？
