  1. Web service (Network AM) should recognize the command prompts for Pica8 and Indigo (OF) modes
- 1. In Indigo mode, there is a race condition between the ofprotocol service starting and the find-env script that runs to pull/set boot parameters, including the OF controller params. The current fix is to run a script that copies a different ofprotocol start script over original, and rely on the runsv service to restart the ofprotocol service after it detects this change. The alternate start script essentially pulls now stable env params (incl. all passed boot params) to correct configure the path to OF controller. The implication is that either we fix the race condition, or we instruct the web service to execute the workaround.
+ 1. In Indigo mode, there is a race condition between the ofprotocol service starting and the find-env script being able to pull all boot params - I think. Consequently, the ofprotocol service that talks to the controller is running blind. The reason I think it's a race condn. is since we see those boot params set when we print env vars, but the ofprotocol svc hasn't picket them up. The current fix is to restart ofprotocol with alternate script that sources the env params. So, we either fix the race condition, or we instruct the web service to execute the workaround.
  1. Establish repository for FTP based loading of OF image, and set up corresponding u-boot configuration.
