Adafruit Assembled Data Logging shield for Arduino

Post by lemdavis »

I am using the Adafruit Data Logging shield for Arduino with a Adafruit Metro ESP32-S2. I am using the SD card library that came with the Metro board. I have been able to read and write to the SD card, but sometimes the card cannot be mounted. For instance, if I turn the power off and on with the card in the slot, the SD card cannot be mounted. But if I remove the card and reinsert it into the card reader when the power is on, the program runs successfully.

I am using the SD Test example that came with the Metro board library.

Does anyone know why I am seeing this behavior? The card was formatted with the SD card formatter utility suggested by the documentation.

I have not seen that kind of behavior before on these shields. Do you have another SD card to try?
