Hi, I have defined do_reset in my board file, I saw that the definition with same name is refined on reset.c How to make use of it, who is calling do_reset? /opt/u-boot/board/exl/NXZ/board.c:659: multiple definition of `do_reset' arch/arm/lib/libarm.o:/opt/u-boot/arch/arm/lib/reset.c:43: first defined here Regards, Jagan.
