Hi,
I take it you updated using the binary file? Please make sure you used the correct version for your board.
If you have the red SparkFun version, you need to use the OpenLog_Artemis-V10-v19.bin binary.
If you have the older black SparkX version, you need OpenLog_Artemis-X04-v19.bin.
If you compiled the firmware from source, let me know as there are extra things to check.
Best wishes,
Paul
