Result is [here](https://hastebin.com/rijuxupoke.css).\r\n\r\nComments:\r\n- The VCO does not lock\r\n- The VCO output is stuck at about 750MHz. Note that we're using the div 2 output divider, so this is consistent with the 1.5GHz minimum VCO frequency of the HMC830\r\n- Register 0x10 always reads 0x80, which indicates that the VCO AutoCal has not completed, so it appears to be stuck for some reason.\r\n- I tried a few sets of register values, but the main ones I tried were @enjoy-digital's ones here\r\n- Putting in delays in a few places was the only thing that seemed to make a difference, so I wonder if there is some timing thing here (just speculation at this point)\r\n- The board is a bit of a pain to probe due to the small vias and lack of test points. So I haven't done that.\r\n\r\nSuggested paths forward:\r\n1. So that this doesn't hold up getting Sayma working, @sbourdeauducq can you use an external 1.2GHz source? If you don't have one then I believe that we have a PLL eval board that we can post you (program if from a microprocessor or whatever). AFAICT, that should work fine. If you want, I can test this on Monday with out RTM.\r\n2. @gkasprow Can you look at your RTM with the forth CPU that you have and see if the autocal also gets stuck for you. From your previous posts, it seems that it didn't (IIRC your VCO had roughly the correct output frequency). If that works, I can load your register set into my code and see if it works. That would confirm that it's not the register values themselves that are the problem.\r\n\r\nThanks!"},"comment":{"url":"https://api.github.com/repos/m-labs/sinara/issues/comments/373037639","html_url":"https://github.com/m-labs/sinara/issues/472#issuecomment-373037639","issue_url":"https://api.github.com/repos/m-labs/sinara/issues/472","id":373037639,"user":{"login":"gkasprow","id":4325054,"avatar_url":"https://avatars3.githubusercontent.com/u/4325054?v=4","gravatar_id":"","url":"https://api.github.com/users/gkasprow","html_url":"https://github.com/gkasprow","followers_url":"https://api.github.com/users/gkasprow/followers","following_url":"https://api.github.com/users/gkasprow/following{/other_user}","gists_url":"https://api.github.com/users/gkasprow/gists{/gist_id}","starred_url":"https://api.github.com/users/gkasprow/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/gkasprow/subscriptions","organizations_url":"https://api.github.com/users/gkasprow/orgs","repos_url":"https://api.github.com/users/gkasprow/repos","events_url":"https://api.github.com/users/gkasprow/events{/privacy}","received_events_url":"https://api.github.com/users/gkasprow/received_events","type":"User","site_admin":false},"created_at":"2018-03-14T14:20:31Z","updated_at":"2018-03-14T14:20:31Z","author_association":"COLLABORATOR","body":"@hartytp did you set the muxes correctly?\r\ndidn't you kill the chip by ESD by chance?:)\r\nAnyway, I will replace it with new one.
