CPRI VSS buffer size cause an error

[xinshuozhang]

Hello

I am using B4860SOC. When I set the CPRI VSS buffer size big, the test demo will have a MMUInit error.

How can I find the problem?

Hello xinshuo zhang,

Can you please be more specific?

What buffer do you modify? From what size and to what size?

Is the error during building or running? Can you provide more information?

Thanks.

你好，

我使用的是CW10.8.3

每一路CPRI的速率设置成2.457G，以太网的P指针设置成20

这个时候每个cpri模块的vss_tx_buffer 4行4列4字节，程序运行正常

修改每一路CPRI的速率设置成2.457G，以太网的P指针设置成62

这个时候每个cpri模块的vss_tx_buffer 46行4列4字节，程序在初始化的时候出错，MMUinit错误

还有我们现在想把PA侧的DDR修改成4G，这个时候怎么修改DSP的l3k文件呢？
