Unable to boot OpenBMC image in QEMU for AST2500

[Stephen Beckwith]

Greetings,
     I am working on a Proof-of-Concept for OpenBMC.  I am familiar with
SP/BMC setups using proprietary code.   I have successfully built the
OpenBMC project (in a VM running Ubuntu 18.04) as well as
building/installing the eSDK.  Note: system was built from a ZIP from
github, git clone failed due to access rights.
    When I completed the process, I tried to load the available image into
QEMU for ARM (which was also built) and received the following error(s),
depending upon the directory from which this is run (which is also a
question, why the difference?)
  I was successful in booting the Poky example from Yocto for both x86 and
ARM into the respective QEMU machines, for the minimal image.
  Any pointers would be greatly provided.

Regards,
Stephen Beckwith
