If the .S files (assembler source files) are used via the likes of (from looking at some vintage of config/rules.mk on the web): $(SOBJS): $(REPORT_BUILD) $(AS) -o $@ $(DEFINES) $(ASFLAGS) $($(notdir $<)_FLAGS) = $(LOCAL_INCLUDES) -c $< then the -mcpu=3Dcortex-a7 is likely not involved. Instead such a context would suggest needing to supply some option in ASFLAGS for the $(ASFLAGS) expansion, an option appropriate to whatever the assembler command is [expansion of $(AS)]. =3D=3D=3D Mark Millard markmi at dsl-only.net
