I followed the instructions in the following link:
wiki.analog.com/.../zynq_images
In section: Preparing the image
The SD card includes a few images on it's BOOT partition. One of these images needs to be selected before the system will boot properly. In order to run any of these images, just copy the images from the subdirectory into the base directory, and then boot it. For newer versions of the SD card, uImage files are in subdirectories for FPGA board generation. Be sure to move the correct uImage into the root of the BOOT partition as well.
I did the following steps:
1) partition the 8GB SD card to 2 partitions: 64MB and the second. The 64MB partition is set to Fat32 format, the second partition is set to ext4 format.
2) write the 2018_R1-2018_06_26.img(which is got from ADI web page) to the ext4 partition with the tool Win32DiskImager.
3) connect a HDMI cable from zedboar to monitor
4) insert the SD to zedboard and power on.
The monitor kept dark and nothing displayed.
Is there any step missed by me?
Thanks and Best Regards,
