Regarding the board: SparkFun IoT RedBoard - RP2350 - Arduino R4 kompatibles development board - SparkFun WRL-27708

The internal SD card module can’t get initialized. When I insert the SD card and try to execute SD.begin I always get a failed message. Can someone help me resolving this? Which pin is the correct one for that board and is the SD.h library the correct one? Or can someone come up even with an example?

Can you try a different SD card? What is the failed msg? Paste more info here

I already tried other SD cards.

I just use SD.h and therefore I don’t get an error message, it just fails. My .ino code looks like this:

void setup() {
Serial.begin(9600);
while (!Serial);

Wire.begin();

// Init SD-Karte
if (!SD.begin(chipSelect)) {
Serial.println(“SD card not initialized”);
while (1);
}
}

I also used the example codes and it also couldn’t get initialized. Which one is the correct chip select?
