I am currently trying to build a custom Linux for Zedboard. Supported Yocto versions are limited for Xilinx: https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/18841883/Yocto. I chose Gatesgarth because It has more recipes than Honister. And there is no meta-xilinx layer for Langdale. I followed two tutorials I found on Youtube. The first one using a Zedboard: https://youtu.be/XPnmB-THjiY and the second one using Zybo Board: https://youtu.be/FMCfn0zwhaQ. I built an Image, formatted an sd card, copy the files, inserted the sd card to the Zedboard and turn on the power. But, it didn't boot. There is no single message on Putty terminal. After some research, I found the same situation for ZC702 board: https://stackoverflow.com/questions/68098124/zc702-not-booting-up-my-yocto-created-build. So,now I want to try the Zeus version. At least, I found a tutorial for Zeus: https://pcotret.github.io/yocto-zedboard-101/.
