The most recent version released was -`Yosemite v3 <https://www.opencompute.org/documents/ocp-yosemite-v3-platform-design-specification-1v16-pdf>`__. - -Yosemite v3.5 is an iteration on this design, and is very similar: there's a -baseboard with a BMC, and 4 server slots. The new server board design termed -"CraterLake" includes a Bridge IC (BIC), with room for expansion boards to -include various compute accelerators (video, inferencing, etc). At the moment, -only the first server slot's BIC is included. - -Yosemite v3.5 is itself a sled which fits into a 40U chassis, and 3 sleds -can be fit into a chassis. See `here <https://www.opencompute.org/products/423/wiwynn-yosemite-v3-server>`__ -for an example. - -In this generation, the BMC is an AST2600 and each BIC is an AST1030. The BMC -runs `OpenBMC <https://github.com/facebook/openbmc>`__, and the BIC runs -`OpenBIC <https://github.com/facebook/openbic>`__. - -Firmware images can be retrieved from the Github releases or built from the -source code, see the README's for instructions on that. This image uses the -"fby35" machine recipe from OpenBMC, and the "yv35-cl" target from OpenBIC. -Some reference images can also be found here: - -.. code-block:: bash - - $ wget https://github.com/facebook/openbmc/releases/download/openbmc-e2294ff5d31d/fby35.mtd - $ wget https://github.com/peterdelevoryas/OpenBIC/releases/download/oby35-cl-2022.13.01/Y35BCL.elf - -Since this machine has multiple SoC's, each with their own serial console, the -recommended way to run it is to allocate a pseudoterminal for each serial -console and let the monitor use stdio.
