system id not found when download software

Honored Contributor II

hi everyone: 

when i run as=> nios ii hardware, it shows a error:"Connected system ID hash not found on target at expected base address." 

then i click system id properties, it shows that the system id not found:  

i retry sometimes, but it still not wrok; 

so i think maybe something wrong when i configure the hardware. but i check the connection of the Qsys, i still did not find something wrong:  

i post my connections , can someone help me to find if there are something wrong?

oh, i found the reason. 

the pll's reset should be low after reset, so the reason maybe the nios did not have clk.
