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 https://github.com/umiddelb/aarch64/wiki/Install-CentOS-7-on-your-favourite-ARMv8-ARM64-AArch64-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-... which uses 4.19

Please let us know how it went.

Thanks. Pablo.
