Hi All,
Very new to arduino and have been struggling with SD card reader. I'm trying to play an audio from the SD Card and get the "SD fail" everytime. I then tried the CardInfo.ino from SD Library and Quickstart.ino from SDFat Library to see if my SD Card is detected. In both, I always get error and Initialization fail.
Reformatted the card into FAT32, tried Windows format and the SD Card Formatter, and plugged back in. Quickstart still shows "initialization fail", but the interesting thing is
If you push the card in at the right moment after the "Initializing SD Card" prompt on the serial monitor, it can read. When you re-run the code with it already inserted, it wont.
and now I don't know what else to do as all the wiring is correct.
Things I've done :
- Made sure CS is correct (Pin 10)
- Tried 5V and 3.3V supply
- Tried 3 different SD Cards (2 x 32GB cards, 1 x 8GB card, all formatted FAT32)
- Tried different SD Card Formatter
SD Card reader I used are labeled XC4386, a pretty standard SD Card adapter module, and a 8GB SD Card I have lying around.
Any help would be appreciated. Thanks!
Edit:
Here's the connection diagram
and the code is basically example codes from library of SDFat and Built in SD.
Here's the CardInfo.ino
/*
SD card test
This example shows how use the utility libraries on which the'
SD library is based in order to get info about your SD card.
Very useful for testing a card when you're not sure whether its working or not.
The circuit:
SD card attached to SPI bus as follows:
** MOSI - pin 11 on Arduino Uno/Duemilanove/Diecimila
** MISO - pin 12 on Arduino Uno/Duemilanove/Diecimila
** CLK - pin 13 on Arduino Uno/Duemilanove/Diecimila
** CS - depends on your SD card shield or module.
Pin 4 used here for consistency with other Arduino examples

// include the SD library:

while (!Serial) {

}
Serial.print("\nInitializing SD card...");
// we'll use the initialization code from the utility libraries
// since we're just testing if the card is working!
if (!card.init(SPI_HALF_SPEED, chipSelect)) {
Serial.println("initialization failed. Things to check:");
Serial.println("* is a card inserted?");
Serial.println("* is your wiring correct?");
Serial.println("* did you change the chipSelect pin to match your shield or module?");
while (1);
} else {
Serial.println("Wiring is correct and a card is present.");
}
// print the type of card
Serial.println();
Serial.print("Card type: ");
switch (card.type()) {
case SD_CARD_TYPE_SD1:
Serial.println("SD1");

Serial.println("SD2");
break;

Serial.println("SDHC");

default:
Serial.println("Unknown");
}
// Now we will try to open the 'volume'/'partition' - it should be FAT16 or FAT32
if (!volume.init(card)) {
Serial.println("Could not find FAT16/FAT32 partition.\nMake sure you've formatted the card");
while (1);
}
Serial.print("Clusters: ");
Serial.println(volume.clusterCount());
Serial.print("Blocks x Cluster: ");
Serial.println(volume.blocksPerCluster());
Serial.print("Total Blocks: ");
Serial.println(volume.blocksPerCluster() * volume.clusterCount());
Serial.println();
// print the type and size of the first FAT-type volume
uint32_t volumesize;
Serial.print("Volume type is: FAT");
Serial.println(volume.fatType(), DEC);
volumesize = volume.blocksPerCluster(); // clusters are collections of blocks
volumesize *= volume.clusterCount(); // we'll have a lot of clusters
volumesize /= 2; // SD card blocks are always 512 bytes (2 blocks are 1KB)
Serial.print("Volume size (Kb): ");
Serial.println(volumesize);
Serial.print("Volume size (Mb): ");
volumesize /= 1024;
Serial.println(volumesize);
Serial.print("Volume size (Gb): ");
Serial.println((float)volumesize / 1024.0);
Serial.println("\nFiles found on the card (name, date and size in bytes): ");
root.openRoot(volume);
// list all files in the card with date and size
root.ls(LS_R | LS_DATE | LS_SIZE);
}
void loop(void) {
}
the output of the Cardinfo.ino is this when it's pushed in at the right timing
Initializing SD card...Wiring is correct and a card is present.

When it's left in and I rerun the code
Initializing SD card...initialization failed. Things to check:
* is a card inserted?
* is your wiring correct?
* did you change the chipSelect pin to match your shield or module?

and this one just outputs

Do not reformat the card!
Is the card correctly inserted?
Is chipSelect set to the correct value?
Does another SPI device need to be disabled?
Is there a wiring/soldering problem?
