> take your 3.3 volt bench supply and bypass the 3.3v switcher. No change!
I took out the switcher and wired an LDO into the test points, same symptoms as before. The LDO got hot, which is why I went with a switcher - it's got to drop 12-17v down to 3.3v with enough current to drive the cpu, ethernet, mp3 chip, eeproms, and oled logic. But the board worked, and still buzzed. So, it's NOT the inductors! Whew. _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
