Hi hangyuxuan19910802,
If your board was functioning before you updated the flash with a design you compiled yourself, I would think that maybe the flash update was not successful or the aocx file was somehow invalid.
Depending on the board you have (A7 or D5), I would reprogram the flash with the factory design for 13.1 I previously posted using the "aocl flash <design>.aocx" command. Once you have done that, power down your system fully (not only reboot) and power it back up. Then check if you can do "aocl diagnostic" again.
Thanks,
G

Thank you gigi!!
I tried the aocx your provided in your opencl_13.1_a7_factory.zip (
http://www.alteraforum.com/forum/attachment.php?attachmentid=8813&d=1398896333). After cool reboot, it did work when I run
$aocl diagnostic and I could see the communication information. But, when I burnt the
hello_world.aocx again, it crashed as before. Some hint is when I ran this one $lspci | grep Altera, there was no output. Does it probably mean something wrong with pcie driver installation? I am using pcie_385n_a7. Am i missing some steps in between? Thanks!
