+
+---------------
+
+
+Saner again:
+
+Get http://developer.axis.com/download/old/devboard/R1_1_0/devboard-R1_1_0.tgz
+And the cris-dist debian package (we're using 1.16-1).
+
+PATH=/usr/local/cris:$PATH
+
+Build the axis dev env thing with 
+"prefix=/space/axis/matt/R1_1_0-prefix ./install"
+
+You'll actually end up with some images which could be flashed, I haven't tried
+them.
+
+PATH=/space/axis/matt/devboard-R1_1_0/devboard/tools:$PATH
+(includes /usr/local/cris too)
+
+In dropbear dir:
+  ./configure CC=gcc_cris CFLAGS="-melinux -muclibc=/space/axis/matt/R1_1_0-prefix -Wall -O2 -DELINUX" --disable-zlib --disable-syslog --host=cris LDFLAGS="-melinux -muclibc=/space/axis/matt/R1_1_0-prefix"
+
+make, it should work.
+
+If you strip it, it won't work. -Os should work.
