Help to create a new file in Sd2Card. about sdfat

pavel-perina,

Change this:
if (sd.cardBegin(SD_CHIP_SELECT, SPI_HALF_SPEED)) {

To this:
if (sd.begin(SD_CHIP_SELECT, SPI_HALF_SPEED)) {

And this will be the result:

Boot up ...
INFO: sd.cardBegin() took 18ms
YYYY-MM.csv
File opened
Line printed
File written
OK

Same here, I've attached almost minimal sketch to reproduce bug. Might be in my code, perhaps I forgot to initialize something. file.open either resets arduino or it halts and initialization often takes 20-25ms (i'm used to 100ms) ... perhaps it depends if card was initalized already or disconnected from power before test). Anyways, file.open never returns.
I will try to copy sdout stream from getline example, at least example works.

Failing code: sketch_jun17a.zip
Warning: code sets pin 4 to output and high ... just in case you have something there

PS: ofstream fails to open file and ofstream.good() is false, I have certainly some silly error in my code, but at least it does not crash.
