Which GPU and driver module do you use?

Ubuntu did not recognize the NVMe device as installation target due to an internal bug.

Eg. @tle reported this error as
> Failed attempt to install Ubuntu Server 19.10 because the installer failed to pick up NVMe drive correctly

I have documented a workaround in my wiki user page:

Firmware / Re: [Guide] How to run firmware temporariliy

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

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

I asked them via mail. This was the answer from today.

Great news! Do you have a URL of their home page for us?

Blackbird / Re: How to connect HDD activity LED?
« on: February 12, 2020, 04:11:27 pm »
You could use (I did) something like this with a 150 Ohm resistor inline on one of the legs and connect to pins 14 and 15.

and use some shrink tubing to insulate.

Shrink tubing is a good idea, I already have thought about using my Rapsberry Pi jumper cables...

Why do I need the 150 Ohm resistor for Pin 15, is 3.3 V too much?

You can verify the firmware with Flashrom and a Bus Pirate.

I have a CH341A device which is supported by the flashrom Linux program but I could not yet find instructions which parts of the memory are relevant for calculating the checksums and
also want to avoid removing the flash chips from the socket just to read them (perhaps this it not required since the flash update is possible from within OpenBMC but if OpenBMC is
compromised it could manipulate the reported checksum too).

Blackbird / How to connect HDD activity LED?
« on: February 11, 2020, 03:52:36 pm »
The User Guide for Blackbird explains on pages 18 + 19 the J9800 Front Panel pins to connect eg. LEDs like HDD activity, Power LED and NIC LEDs:

What is unclear to me is how I can connect a usual two-pin HDD LED plug with the front panel pins since

- I can see only one Pin (#14) for the "HDD activity LED cathode" but
- no obvious PIN for the HDD activity LED anode.

So the two-pin HDD LED plug from my case has no obvious two neighbored pins to be plugged into.

1. Which front panel pin should be used for the anode of the LED?
2. Which cable could I use to split the two-pin HDD LED plug from my case into two separate pins for a reliable connection?

How could I check the integrity of the installed (flashed) firmware of a Blackbird (or Talos) eg. against the officially downloadable firmware files (which are cryptographically signed)?

That's sad. Would be interesting to know what caused this error.

I will come back here with the RMA result (but I guess it is hard to diagnose)

I will try it out this weekend and come back with my results

OK, I have tested my Blackbird with a minimal hardware attached and the planar unmounted (detached) from the case's mouting points and I can reproduce the error
(see the attached log captured via the serial console + the picture of the planar).

Oh unlucky day, I have to open an RMA...

Sorry but are we obliged to register on the site just to download a patch? It seems excessive to me ... Now for example it denies me access ...

I guess the link is using the wrong path (perhaps to a private repo or the internal CI/CD artefacts).

Nevertheless I think you can find the patches here eg. in the master branch:

On Amazon a bestseller

THX :-) Is was mixing up this with the MSI M.2 Epander Aero (for 4 M.2 SSDs) which I couldn't find to buy at Amazon or my local computer stores (it was mentioned it ct 3.2020 page 77):

General Discussion / AMD Radeon Pro WX3200 working with Blackbird?
« on: February 09, 2020, 05:18:45 pm »
I am considering to buy a WX3200 because it is "cheap(er)" (about 220 USD) and supports newer standards like OpenGL 4.6 and Vulkan 1.1.

Has anybody tried out this GPU on a Blackbird (or Talos), does it work and with which OS and module (driver)?

According to AMD this GPU uses Polaris architecture.
I have read rumors that it is a Polaris 12 GPU similar to the Radeon RX 550 LE.

Thanks a lot for your quick response, I will try it out this weekend and come back with my results

I still have the problems described in the first post.

To avoid lengthy posts in this question I will close this question.

I have opened a new question that contains detailed logs now for better diagnostics and a more precise question:,52.0.html
