Crashing Phosphor Settings Manager

[David Müller (ELSOFT AG)]

Hello

I have some trouble to bring up OpenBMC on your custom, AST2500 based
design. I suspect some kind of misconfiguration but was unable to
pin-point it so far.
Any idea what could be wrong with my setup or hints how to debug this issue?


root at test:~# cat /etc/os-release

NAME="Phosphor OpenBMC (Phosphor OpenBMC Project Reference Distro)"
VERSION="v1.99.8-94"

PRETTY_NAME="Phosphor OpenBMC (Phosphor OpenBMC Project Reference
Distro) v1.99.8-94"
BUILD_ID="v1.99.8"


The message log is full of this kind of messages:

The "obmcutil" tool crashes with the following dump:

I have stripped down the board wiring config file to the bare minimum
(at least I think so), but also this does not help.
