    huangjz0712_1516091

      Line width is 6.6mil differential. line spacing are also 12.6mil impedance value is about 90 ohms.ARM-JTAG  and FPGA-JTAG  all is  normal work .And voltage is normal.Now the problem is unable to enter USB3.0 super speed mode? Does the electrical characteristics meet the identification requirements? In addition , When I downloaded cypress the slave fifo firmware example, it appeared an initialization hardware error。And I enter my firmware program is normal only in USB2.0 work normal.I have set CyU3PConennectState (CyTrue,CyTrue). Thanks.
