Description

Why does TEMAC not work after creating my design from Base System Builder?

Solution

Base System Builder allows you to set a clock frequency that is too slow for gigabit performance in the TEMAC's local link interface. As a result, the PLB clock frequency cannot be lower than 62.5 MHz for gigabit performance.  

Please refer to the signals LlinkTemac0_CLK and LlinkTemac1_CLK in the xps_ll_temac data sheet.
