Hello,

I’ve just built a v2.5.1 PYNQ image for Eclypse-Z7 board on Ubuntu 18.04 using PetaLinux and Vivado 2019.1, board agnostic image (PREBUILT=bionic.arm.2.5.img) and source distribution (PYNQ\_SDIST=pynq-2.5.tar.gz).

The process went just fine and I get a 5.40Gb .img file that I flash on a 32Gb SDCard. When I finally try to boot on the card, the board cannot boot and I do not understand why. Here’s my putty log.

Thanks for your help,  
Thibaut
