SD card initialization fails after SD power down/new init sequence #1103
Description
What steps will reproduce the problem?
1. Init SD card
2. Turn SD card off (by cutting power to SD card, but also to all other SD
input pins)
3. Turn SD card on
4. Initialize SD card again
What is the expected output? What do you see instead?
The expected output would be to have the SD card re-initialize itself. Instead,
the second initialization fails.
I have tracked the failure cause to SDFile.openRoot method that return failure
if the root had been already opened.
What version of the Arduino software are you using? On what operating
system? Which Arduino board are you using?
Arduino IDE 1.0.1
Mac OS X
Custom board
Please provide any additional information below.
A fix can be implemented, for example by calling a method that resets the state
of the SDClass object in the initialization routine, making sure we start from
a blank state.
I am willing to implement the fix, but just want to make sure I implement it
the way people would like it.
