Hello -

  I'm just getting started in the work of Arm based boards.  I'd like to use
CentOS on my Orange Pi Zero.  I've followed the instructions here:
https://wiki.centos.org/SpecialInterestGroup/AltArch/armhfp but the system
does not appear boot - no red LED, no ethernet activity.  It does when I use
one of the Orange Pi provided Ubuntu images.

  I'm using the /usr/share/uboot/orangepi_zero/u-boot-sunxi-with-spl.bin uboot
image, and CentOS-Userland-7-armv7hl-generic-Minimal-1804-sda.raw.xz centos
image.  Comparing the contents of partition 1 which seems to be the boot
partition, on the Orange Pi image I see:

# ls -l /mnt
total 4654
-rwxr-xr-x. 1 root root     538 Nov  9  2016 boot.scr*
-rwxr-xr-x. 1 root root   34864 Nov  9  2016 script.bin*
-rwxr-xr-x. 1 root root   49292 Nov  9  2016 sys_config.fex*
-rwxr-xr-x. 1 root root 4679592 Nov  9  2016 uImage*

while on the Centos image I see:

-rwxr-xr-x. 1 root root 3911652 May  1 06:26 start_x.elf*

which seems more Raspberry Pi oriented?

  Is there something I'm missing?
