  1. 5 weeks later: no reaction from digilent well done
  2. Hi, I try to create a boot image for a zybo zynq7 board with yocto for an academic project. I use the zeus branch for yocto and all needed layers and the creating process runs without any errors. I use Ubuntu 20.04, the zeus branch isn't validated with this version so there is a warning in the beginning. To create I used the following layers: - meta-xilinx-bsp - meta-xilinx-contrib - meta-xilinx-tools - meta-oe - meta-python In local.conf ich used MACHINE ?= "zynq-zybo7" and added the following lines: LICENSE_FLAGS_WHITELIST += "xilinx" EXTRA_IMAGEDEPENDS_append = " u-boot-zynq-scr" UBOOT_EXTLINUX = "1" UBOOT_EXTLINUX_FDT = "../${MACHINE}-system.dtb" UBOOT_EXTLINUX_CONSOLE = "console=ttyPS0,${115200}" UBOOT_EXTLINUX_ROOT = "root=/dev/mmcblk0p2" UBOOT_EXTLINUX_KERNEL_ARGS_append = " earlycon clk_ignore_unused" When I start the board an boot from SD card, there is running a process, I think it could be the booting, but in the serial console there is are hex codes like in the attached image. I thought it could be a wrong BAUD but the problem remains with every BAUD. I also tried different settings for parity, and the number of stop bits and data bits. Does someone know the problem? Best regards Mike K
