Why not remove the "-msoft-float" as well. U-Boot does not use soft float and why then the requirement to use a compiler which supports soft-float??? > > -PLATFORM_CPPFLAGS += -march=armv4 > # ========================================================================= > # > # Supply options according to compiler version > # > # ========================================================================= > +PLATFORM_CPPFLAGS +=$(call cc-option,-mcpu=arm920t,-march=armv4) > PLATFORM_CPPFLAGS +=$(call cc-option,-mapcs-32,-mabi=apcs-gnu) > PLATFORM_RELFLAGS +=$(call cc-option,-mshort-load-bytes,$(call > cc-option,-malignment-traps,)) > --- u-boot.orig/cpu/arm926ejs/config.mk 2008-01-13 10:42:55.000000000 -0800 > +++ u-boot/cpu/arm926ejs/config.mk 2008-01-13 11:04:56.000000000 -0800 > @@ -24,11 +24,11 @@ > PLATFORM_RELFLAGS += -fno-strict-aliasing -fno-common -ffixed-r8 \ > -msoft-float > > -PLATFORM_CPPFLAGS += -march=armv4 > # ========================================================================= > # > # Supply options according to compiler version > # > # ========================================================================= > +PLATFORM_CPPFLAGS +=$(call cc-option,-mcpu=arm926ej-s,-march=armv4) > PLATFORM_CPPFLAGS +=$(call cc-option,-mapcs-32,-mabi=apcs-gnu) > PLATFORM_RELFLAGS +=$(call cc-option,-mshort-load-bytes,$(call > cc-option,-malignment-traps,)) > Is this correct? ARM926EJ-S is ARMV5 architecture, not ARMV4.
