I'm sorry, but I cann't understand you clearly. what do you mean by writting this? compare two different versions? if so, which two version? > index 3e145ad..19f0f0b 100644 > --- a/include/malloc.h > +++ b/include/malloc.h > @@ -850,7 +850,7 @@ extern Void_t* sbrk(); > #endif > > #ifndef MORECORE_CLEARS > -#define MORECORE_CLEARS 1 > +#define MORECORE_CLEARS 0 > #endif > > #endif /* INTERNAL_LINUX_C_LIB */ I read the malloc.h file in u-boot-2010.09. it's content like below: #ifdef INTERNAL_LINUX_C_LIB 819 820 #if __STD_C 821 822 Void_t * __default_morecore_init (ptrdiff_t); 823 Void_t *(*__morecore)(ptrdiff_t) = __default_morecore_init; 824 825 #else 826 827 Void_t * __default_morecore_init (); 828 Void_t *(*__morecore)() = __default_morecore_init; 829 830 #endif /* __STD_C */ 831 832 #define MORECORE (*__morecore) 833 #define MORECORE_FAILURE 0 834 #define MORECORE_CLEARS 1 #else /* INTERNAL_LINUX_C_LIB */ 837 838 #if __STD_C 839 extern Void_t* sbrk(ptrdiff_t); 840 #else 841 extern Void_t* sbrk(); 842 #endif 843 844 #ifndef MORECORE 845 #define MORECORE sbrk 846 #endif 847 848 #ifndef MORECORE_FAILURE 849 #define MORECORE_FAILURE -1 850 #endif 851 852 #ifndef MORECORE_CLEARS 853 #define MORECORE_CLEARS 1 854 #endif 855 856 #endif /* INTERNAL_LINUX_C_LIB */ Do you mean that I should change MORECORE_CLEARS from 1 to 0? -- Best regards, terry _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
