For me it's a pleasure using it.

It is like magic to my eyes to see a Linux prompt in this tiny module.

Thank you!

No worries.  I'm glad you were able to get the BMC running; it's great
to see more users of this technology!

Sorry, I need to read better.

Thank you.

I am going to try the patches now.

they are welcome to do so!

Thank you for your reply.

I reflashed (same build) the BMC module with a hotplug. Now it works
like a charm, it got an ip, I can log through ssh, reboot, etc..

But now I have a new problem. If I try to boot from a halted system,
with BMC module attached, the system fires up but Coreboot hangs:

Unable to detect valid memory on any nodes.  Halting!
mct_d: fatalexit

If I remove the BMC module the system boots fine.

I have 4 Micron MT18JSF25672PDZ-1G4F1DD modules, located in CPU1 orange

I attach both console logs.

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

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

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

Are you using the latest coreboot? AFAIK coreboot was patched to
OpenBMC, so you need a new version with the patches.
