Query regarding using the Redfish in OpenBMC

[Mike Jones]

Some progress. On the hacked build, there were three problems:

1) bmcweb failed at start
2) Wrong port
3) Can’t login

The failure was found by compiling it with logging. /var/log/redfish was missing. Touching the file and executing bmcweb& got it up.

Some doc said port 8080, but it is 18080.

DHCP is not working, so I boot to console with hdmi and keyboard and make a static address with ifconfig. Will deal with later.

Login was because groups were missing. Found where that was in meta-phosphor and added.

Now I have the webui up.

On the evb build, it is trying to build images that fail when checking file size. I think this is because meta-phosphor has IMAGE_FSTYPES += with some mtb images, and meta-rasberrypi has IMAGE_FSTYPES ?= and I assume += wins or mixes. I think if I add IMAGE_FSTYPES = in local.conf, it would override it and probably work.

Waiting for a long rebuild...
