I had to update the Nano (V1 hardware) firmware to V. 3.01 before it accepted my 2GB SD memory (formattet as FAT32, which should be supported by V 3.01). Now I can “see” the device from my Vista, and transfer files. When I try to save data from the Nano (and configuration and BMP’s), it says “No File” in the lower right corner of the display - and yes, I have stored placeholder files for data, configuration and BMP’s (fetched from this site).
Is there any way of getting any further error description in order to be able to store on the SD?
