Is there a document or comment describing the memory map between the sensor/FPGA/ETRAX100?
Not well documented :-(
You may find x313.h useful (os/linux/arch/cris/rivers/x313.h). There is a fpcf program in the camera (source - apps/fpcf/fpcf.c) that you can play with - it provides low level access to the FPGA interface.
