Intel-BMC on github

Fri Mar 22 02:52:21 AEDT 2019

Hello James,

Good to see the Intel BMC code is on github so we can give it a try and use it.

In the mean time we downloaded and built the image without problem.

The issue is that we don't have a Wolfpass board. In order to get around this I create a woldpass-bmc devices in the OpenBMC qemu.

As far as I now the major difference is in the flash size(I added a 64 MB part), I also updated the strapping according to the schematic.

I can use this device in Qemu and it starts the image I built for the s2600wf (if I catenate two of them to achieve the 64MB).

The issue is that if I try the wolfpass image u-boot is starting,  it also reports the kernel is loaded etc but it freezes after is passes control to the kernel.

I included the qemu logging below:

Intel announces that its internal repository based on the OpenBMC project is being made public on github under the organization name of Intel-BMC.

Intel is sharing the latest internal repositories in response to requests from partners and customers to be able to build an OpenBMC firmware image that will run on an existing Intel server platform. The repositories include content that has not yet been upstreamed to the LF OpenBMC project.

Currently the only supported platform is the Wolf Pass platform (S2600WF). Support for more platforms will be added in the future.

The Intel-BMC can be found at https://github.com/Intel-BMC<https://github.com/Intel-BMC/openbmc>.
For further information, please refer to the readme file (https://github.com/Intel-BMC/openbmc/blob/intel/README.md).
