Shows sd card not inserted even if I have inserted 16 GB SD card and it is formatted. I was running the usbMsc sketch on the arduinoIDE. Same error in other programs related to sd card. How to fix it?
Have you been able to use the SD card with Spresense before?
The sd card is not being detected because of the loose b2b connector. I have to press the main board onto the extension board everytime I run the sd card sketch.
Have you used the small spacers that comes with the extension board to attach the two boards together?
Please see this picture:
@TE-KarlKomierowski The main board comes loose despite the spacers (in my experience) and this is just from moving the USB cable around a bit to plug the other end into the computer. It's not visibly loose, it just seems that the connector between the two boards has poor mating, which results in it sometimes losing the connection.
PS: I haven't been using an SD card, just the audio jack output, but I also frequently experienced a lack of sound because the two boards had become loose.
