Musicmaker SD card not detected

Post by sraaf »

Hi all,

I'm a long-time arduino programmer and educator. I'm running into an issue with the musicmaker shield not recognizing the sd card that's stumped me. Anyone got a solve for this one?

After trying every conceivable way to troubleshoot the issue (including reformatting the SD card to exFAT, running the player_interrupts sketch, triple-checking the soldering, making sure the sound filename is set to track001.mpg, etc), I've started grasping at straws. The (brand new) SD card I'm using is a SanDisk Ultra 64GB microSDXC UHS-I Card. Is it possible that the 64GB card is too big for the card reader on the MusicMaker?

I found conflicting info on these two web pages about the size of SD card that may be used in the MusicMaker:
- This adafruit page says "You can use any FAT16/FAT32 formatted card from 64M up to 8G." (ie, upper limit of 8GB)
https://learn.adafruit.com/adafruit-mus ... y?view=all

- The sales page for this shield on adafruit doesn't state an upper limit to the size of SD card. It simply says, :
"MicroSD card socket, for any FAT16/FAT32 formatted SD card from 64Mb or greater."
https://www.adafruit.com/product/1788

Which of these is true? Could using a 64GB card be the issue?
Is the problem perhaps the exFAT formatting (rather than FAT16/FAT32)?

thanks in advance.

It's most likely that. Only FAT16/FAT32 is supported. Making sure the SD card is actually formatted FAT16/FAT32 can sometimes be tricky. Most OS's just hide that level of detail. And exFAT is probably the most common default.

Try formatting it FAT32 and see if that helps.
