Title: [Guide] How to run firmware temporariliy
Post by: tle on February 15, 2020, 09:01:39 pm

I've been playing around with custom built OpenPower firmware. One tips I pick up from Stewart Smith is to use `mbox` to load the firmware from file instead of mtd:

Code: [Select]

# SSH into OpenBMC
# Load firmware from file
$ mboxctl --backend file:/tmp/blackbird.pnor
$ obmcutil poweron
# once done with testing
$ obmcutil poweroff
$ mboxctl --backend mtd

Did you find a way to temporarily update PNOR and OpenBMC together (in sync) since this is the recommended procedure...?

The wiki also describes how to run the OpenBMC firmware temporariliy but I am not sure how and if this works in sync with a PNOR update
