Woke up this morning sore all over. My neck is really stiff, which implies I went down harder than I thought in Sunday's hockey game. I'm being punished for taking a month off and then playing two games in a night.
Since my chip came back, I've been spending all of my time in the lab. Spent most of the day today probing the board, having parts re-wired, and theorizing, only to find out that the error was that the configuration was wrong -- one of our guys added '8' and '1' together in his head and got 'A' instead of '9'. Four hours later we fix the problem, and poof! the chip's running like clockwork.
For those who have wondered, this is why hardware engineers have to be able to convert hex to binary in their heads.
