Have you tried different SD cards, and cards that you're sure are FAT32 formatted?
I actually just tried this with a Pico and it works fine - however I have a 2GB card that it doesn't appear to work with, but I'm also having trouble with the Espruino WiFi.
I'll try and track this down a bit more as it should really be more resilient, but it might be a few weeks as I'm waiting for a micro SD card breakout.
