Hi all,
On a fresh untar; make xxx_config; make all, I get an error linking the example program hello_world with start.o.
This can be worked around by removing 'examples' from the list of SUBDIRS in the top-level Makefile.
After building, I added 'examples' back in. Strangely, for one set of builds, this solved my problem (and hello_world linked OK, even after a 'make distclean'), but for another set of builds, hello_world wouldn't link even when cpu/arm925t/start.o was present.
I haven't been able to figure out the problem, but I thought I'd report it. This is with a home-built gcc: arm-sony-linux-gcc (GCC) 3.4.3
