Having an issue with the Adafruit SPI Flash SD Card, there seem to be issues communicating via SPI.
I'm running everything via Platform.IO on a Teensy 4.1.
The serial monitor shows:
Initializing SD card...Wiring is correct and a card is present.
Card type: SD2
Could not find FAT16/FAT32 partition.
Make sure you've formatted the card
I've successfully connected this chip to an Arduino Mega already. Any guidance would be appreciated!
