I have completed software lab 7 for the Zedboard. When I run my boot image it seems to run fine except it hangs on the line that tests the Ethernet port in the Test_Peripherals application. After seeing this behavior I decided to run the Test_Peripherals application in a jtag debug mode similar to what was done in SW Lab05. Here when I run the application it steps all the way through the application and does not hang at the line that tests the Ethernet port "Running Interrupt Test for ps7_ethernet_0..." What would cause this problem.
