我用的是官方的EVM板,我的SW5的设置是off ,也就是拨码开关都设置为靠近PCIE插座。在这种设置下,当我插了PCIE网卡(x1),上电串口竟然无反应,此PCIE网卡我已经在PC机上测试过了,可以使用。以下是我不插PCIE网卡的时候串口打印信息。

问题解决了,谢谢大家这么长时间的关注。 Since TI81XX RC supports maximum remote read request size (MRRQS) as 256 bytes, ensure that the EP driver/device you are using doesn't set read request size more than this value. If it does, then modify the driver to set read request size to 256 bytes before building it. Ensuring Maximum Read Request size within 256 Byte limit is required even for any intermediate Switch/Bridge devices in the fabric. 需要改驱动里面read request size,这个每个驱动对应的函数描述不大一样,但是类似,大家可以参考下博通的pcie_set_readrq函数,默认设置的是4096,改成256就行了。 OK。 |
