Actually, for OpenBMC work, hotplugging is often the only way to go. Just be very careful to align the pins correctly the first time; you don't have a second chance if you misalign the pins and fry the module...

Hi,
Now I trying to use your OpenBMC port.
I followed the instructions and everything was fine (compiling, reading and flashing). I waited several minutes after flashing, but the module didn 't blinked like in the vendor rom, nor did it receive an ip.
I halted the system because I thought maybe it needs a cold start.
After this, the system doesn't boot with the module plugged in. The fans begin to spin for approximately 1/4 second, but nothing else.
My two fans (1 cpu & 1 chassis) have 3 pins and are low speed (~1000rpm)
In the case I have to reflash the module, is it possible to hotplug it?
Hotplugging is dangerous and not supported, don't do it.
Thank you very much for your support.
You can use a test clip to externally flash it via a flashing device (not sure which can do 16 pins though, I would inquire on the flashrom mailinglist)
Are you using the latest coreboot? AFAIK coreboot was patched to support OpenBMC, so you need a new version with the patches.
