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

I am a begineer in using the Zynq 7000 ZC706 SoC. I have already booted linux made with Yocto project with meta-xilinx and PREEMPT-RT layers. Everything is working as expected. Though we are not satisfied with the real time performance on Scheduler and Latency tests, however alternatively it could be interesting to compare with another OS like CentOS.

I have followed the procedure on described here to install CentOS using the rootfs files made with yocto and the files in /boot (boot.bin + UImage + dtb).https://github.com/umiddelb/aarch64/wik ... ch64-board

But I am not able to successfully create the OS. I am not having a serial communication with the board, so I cant debug further. I will/can only have a SSH communication once the OS boots up.

Does anyone guide me how can I take this ahead?

I could not find anything aarch64 for that device, all I found was 32 bits.
That said, it seems to have mainline uboot and kernel support (zynq-zc706.dts), so it could be installed using the steps here https://wiki.centos.org/SpecialInterestGroup/AltArch/armhfp
Since we usually don't build uboot for that device, I made a version for you to test, and left it here https://people.centos.org/pgreco/zynq-zc706/
The normal images provided by CentOS use kernel 4.14, but if you need an image with a newer version, we have this test image here https://armv7.dev.centos.org/repos/images/CentOS-Userland-7-armv7hl-generic-Minimal-419-v26-1810-sda.raw.xz which uses 4.19

Please let us know how it went.

Thanks.
Pablo.
