4 years ago The ssith-lmco branch of chipyard has been updated with all the latest GFE-related fixes, which is 'done' for P2-equivalent builds. P1 builds will be enabled when available.
The Hard-enabled AFI is agfi-0fa64c818ce908fea.
It can be built using the cloudgfe-lmco branch of FireSim. The README has been updated with specific context for building the LMCO smoketest example.
There's also now a Minimal CloudGFE setup guide that uses pre-built LMCO smoke-test AFIs. I just need the AWS ID and canonical user IDs to share these files with LMCO (details on that README).
Sample output of the provided smoke tests running on Linux:

Include new updates for matching the GFE memory map. Build an AFI for LM to quickly get up and running. Need to package the necessary host-side software and scripts for communicating with the F1 to avoid going through the lengthy FireSim setup.
