6678 SRIO所用的312.5M时钟是由时钟芯片给出的,现在想确认下这个时钟有没有,或者对不对,是不是跑一个LOOP程序看看能不能过就能说明问题?因为手头没有示波器,所有只能有此一问,忘不吝赐教!

应该是信号完整性问题,
KeyStone 1 SRIO Self Test Kit User’s Guide 有说明这个问题
Throughput are also measure for each test, if data are transferred correctly, but the measured throughput is lower than expected, it may indicate hardware signal integrity issue
