I follow the wiki step. I am try to compile the sd card image.

1. Go to mips/nanonote/server and run autoreconf -fis; ./configure --prefix=/tmp

2. Go back to the root source directory and run make setup.
it give me:
xiangfu at openmobilefree:~/workspace/iris.git$ make setup
make: *** No rule to make target `setup'.  Stop.
xiangfu at openmobilefree:~/workspace/iris.git$ make
make: *** No rule to make target `init.elf', needed by `mips/entry.o'.  Stop.
