I'm pretty sure there's a bootloader on the device that I have, which is a SparkFun OpenLog, -
(SparkFun OpenLog - DEV-13712 - SparkFun Electronics) but I don't know if its an arduino bootloader.
I do know that the device will accept Arduino sketches, since I once did that, inadvertantly (I won't go into that :-[). However I don't know what, if anything, happened to the existing program, which came with the device.
OpenLog firmware is open source and is based on Roland Riegel's FAT library. OpenLog currently supports FAT16 (upto 2GB microSD cards). We're working on FAT32 and would love your help!
I'm afraid that my infernal "tinkering" with the device screwed it up again. :
