After following the no-os setup I was able to get the build done without errors but when I try to run I get the following error "RX MMCM-PLL NOT locked TX MMCM-PLL NOT locked RX OS MMCM-PLL NOT locked clkgen_setup() failed". Kindly Help.
In this case, try first to rebuild the Vivado project using your revision number instead of 1.2. If it doesn't solve the issue, we have to find out all the differences between revisions 1.2 and 2.0.
Let us know how it goes.
