Thanks for the log. Together with the dhd driver sources I could make some sense of it. Perhaps you can try the following hack and see if we make it over the first hurdle.

Thanks, I tried it, but although it looks necessary, there's evidently something else since the result was the same.

This should be ... .signature = ...

That's what you get if you get too confident... :-(

Just mention it in case anyone following along at home with the patches.

I added a log showing it sending the entropy bytes.

Ok. Something is off there. Maybe I tried to be to smart. How does that log statement look which you added?

It's inline with the other logs, it seems to be coming before the actual NVRAM download part

Sorry. I meant how the source code look like. There should be 128 bytes written. 6040 is length of nvram so I am a bit confused.
