Hi Pablo, Thank you very much for the help. Though I performed the same steps from the wiki link, ( https://wiki.centos.org/SpecialInterestGroup/AltArch/armhfp) for Zynq ZC706 using the uboot files you provided and the generic userland image (also the old version with kernel 4.14), but the device *does not* boot up. The DONE leds on the device does not light up at all. At this point I tried the generic userland image files on also the raspberry pi3b+, even the raspberry *does not* boot up. Although userland image provided for particularly raspberry works as expected and boot into the device. I also see that the userland generic image creates three partitions on the drive, two of which are for boot, which does some procedure to detect the board automatically. I was wondering, if it is possible for you to guide me how I can create single boot partition, using the files you provided. There is high possibility that I am doing something wrong. Please let me know what you think, Regards, Piyush D Jadhav On Tue, Apr 9, 2019 at 2:49 AM Pablo Sebastián Greco <pablo at fliagreco.com.ar> wrote: > > El 8/4/19 a las 12:28, Piyush Jadhav escribió: > > I am a begineer in using the Zynq 7000 ZC706 SoC.
