So for big endian kernel builds, just selecting the CONFIG_CPU_BIG_ENDIAN is not sufficient, we also need to manually change the CROSS_COMPILE prefix to arceb-xxx. @Anton, is that what you do for verification builds ! @Noam I presume your defconfig has CONFIG_CROSS_COMPILE or you have set in env variable ? The kernel build system needs to take take care of that. Do you guys have issues with patch below ------------> diff --git a/arch/arc/Makefile b/arch/arc/Makefile index c8230f3395f2..4abcdb89e391 100644 --- a/arch/arc/Makefile +++ b/arch/arc/Makefile @@ -9,8 +9,12 @@ UTS_MACHINE := arc ifeq ($(CROSS_COMPILE),) +ifndef CONFIG_CPU_BIG_ENDIAN +CROSS_COMPILE := arceb-linux- +else CROSS_COMPILE := arc-linux- endif +endif
