I have an existing project that I am working on using a Seeeduino Stalker 3.1. The project works but it is using too much power when sleeping and I traced it to the use of the SD library. I am trying to use the SDfat library instead but receive errors on compile when selecting the Seeed board. I started with the QuickStart SDfat example to eliminate any issues my project might bring in.
Error messages from compile:

I also noticed:
WARNING: library SPI claims to run on avr architecture(s) and may be incompatible with your current board which runs on Seeeduino_Stalker architecture(s).
My project runs OK with SD instead of SDfat even using the SPI library, so I have ignored this error, but perhaps SDfat uses it in a way that SD did not and is exposing that incompatibility.
