Description Pat Ransil 2009-09-11 10:13:09 UTC

Manufacturing has intermittent failures testing the nav knob and ambient light sensor in the MP2 release. Failure rate was about 2% (see attachment) for encoder and 20% to 30% for ambient light sensor test. 

Caleb found a bug in the microcontroller software that explains both bugs.

Test results from SZ.

Ten units were tested 60 times each. There were a total of 3 failures. This rate (3/600=0.5%) is less than earlier testing on the line (4 of 156).

Oops, didn't see this bug until well after it was fixed.

Moving old Baby bugs to new group.  Most of these are probably so old as to be invalid.
