srio回环测试结果

用的是官方给的K1 STK V1.1 中的srio例程 测试的是digital loopback 在6678上测试的时候出现了以下问题  数据不匹配。

请问这是什么问题?那一块出问题了 要怎么解决呢?

请问用的是EVM板吗?对例程有改动吗?

user6510364:

回复 Shine:

您好 我用的是自己画的板子 芯片用的是c6678 例程用的是srio test.c 把里面kestong ddr init()这句话注释掉了 因为用的是digital loopback 模式没用到ddr3

Shine:

回复 user6510364:

SWRITEfrom 0x10802200 to 0x82014000

0x82014000这块是DDR3地址,所以不能把初始化DDR3的函数注释掉。

user6510364:

回复 Shine:

谢谢您,那下面这些问题也是由于初始化ddr3的函数被注释掉导致的吗
External exception happened. MEXPFLAG[3]=0x4000000.Event 122: DMC_CMPA CPU memory protection fault for L1D (and other memory read finally goes through the L1D controller)memory protection exception caused by local access at 0x0Supervisor Read violation

回复 user6510364:

把DDR3初始化函数打开后看能不能消除这个错误。

user6510364:

回复 Shine:

谢谢回复 您的建议我去尝试一下

还有就是 内循环成功之后 为什么无法在memory browser 中看到搬移后的数据呢?

例如 我用swrite格式 将数据from 10802200 to 1080a200 completion code=0 这说明传输成功了。可是我在memory browser 中查看 1080a200这个地址时 显示无法转到指定地址(unable go to specified address) 这是怎么回事儿呢? 期待您的解答!辛苦了

Shine:

回复 user6510364:

请问在运行SRIO例程之前,能通过memory browser查看地址1080a200的数据吗?

user6510364:

回复 Shine:

您好 还没有试过在运行程序之前就去查看地址1080a200的数据。 正常情况下,不运行srio程序也可以直接查看地址 1080a200的数据吗?
