Hello I try to boot a Cora-Z7-10 with u-boot but without success I followed the instructions from here https://u-boot.readthedocs.io/en/latest/board/xilinx/zynq.html built u-boot as follows

export ARCH=arm export CROSS_COMPILE=/usr/bin/arm-linux-gnueabihf- make mrproper make xilinx_zynq_virt_defconfig make

after that i copied the files to the sd card but nothing happens spl/boot.bin -> 121.3 kB u-boot.img -> 1.2 MB

core-z7 is not supported board. That's why you should use fsbl to see something on the console and then you can use u-boot but you need to generate (via DTG) or describe your HW design in device tree.

Thanks, Michal
