I’m trying to use a 64MB micro-SD card in my DSO Nano, but I’m not having any luck. As a baseline, the card works fine in my USB SD card reader, MP3 player, and digital camera. I’ve formatted the card as FAT16 and created the FILExxx.DAT files (using the archive posted).
When I insert the card in the Nano, I can access the FS and FL menus, but I get a “Micro SD Err” when loading or saving files.
Connecting the DSO Nano to my Windows XP workstation, and it shows up as a removable drive, without any media.
