ubuntu 10.04, IDE 1.0.4, Itead leonardo board + SD card board
sketch AnalogLogger from SdFat/examples
runs fine on upload (with or without while(!Serial) )
but leads to card.init failure (I added flash counts on pin13 led)
when leonardo is connected to battery or wall-plug
samething with all Serial removed from .ino
samething with another SD board, another SD card
Any ideas ?
