[Guide] How to run firmware temporariliy
(1/1)
tle:
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: ---# SSH into OpenBMC
# Load firmware from file
$ mboxctl --backend file:/tmp/blackbird.pnor
$ obmcutil poweron
# once done with testing
$ obmcutil poweroff
$ mboxctl --backend mtd
--- End code ---

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

> Always upgrade PNOR and BMC together
> Many mismatched PNOR/BMC version combinations lead to weird failures.
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
