开发例程中测试内存出错问题



各位好:

运行版上提供的例程SRIO,在程序开始部分,测试DDR内存失败:

[C66xx_0] SRIO_SERDES_LOOPBACK test start............................................
Initialize DSP main clock = 100.00MHz/1x10 = 1000MHz
Initialize DDR speed = 66.67MHzx20/1 = 1333.333MTS
Memory pattern filling Test fails at 0x800000f0, Write 0x 0, Readback 0x7f00000000000000
Memory pattern filling Test fails at 0x800000f8, Write 0x 0, Readback 0x7f00000000000000

查了一下,发现其他人也出现过类似问题,回答说是leveling问题,需要调试参数。请问这个

参数具体在哪个函数里面设置。

另:我在ccs的memory viewer里面单独访问出错地址的内存,发现可以正确读写,不过是在没有运行

SRIO程序的情况下,只是挂上板子后运行global default setup。

谢谢!
