I set up a Linux system with planAhead 14.6 on ZC702 board last year. Everything works fine. But I need to add new feature into the PL system now and I want to move to lastest Vivado follow. I generated the bit file and it works in bare metal but there is no display in Linux system. Does it means I also need to update the Linux kernel? How many files I need to update? uImage, devicetree, u-boot and so on.
