Thanks,
Now tried this one (and switching MISO and MOSI). No luck so far. Any suggestions?
(*our doubts are seriously growing to use this Arduino product in our commercial product *).
#include "Arduino.h"
#include "SD.h"
// Vcc to 3.3 volt also tried 5 volt
// miso to pin D89 SPI
// mosi to pin D90 SPI
// SCK to pin D91 SPI
// CS to pin 10
void setup() {
Serial.begin( 115200 );
while (!Serial && millis() < 5000);
Serial.println("Begin");
if (!SD.begin(10))
{
Serial.println("SD card failed!");
}
else
{
Serial.println("SD card success!");
}
}
void loop() {
// put your main code here, to run repeatedly:
}
