[CentOS-devel] Help needed to Install CentOS on Zynq ZC706 ARM cortex A9

[Piyush Jadhav]

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
