For board.c to see them as declared, you have to have them in a header file, namely arch/arm/include/asm/u-boot-arm.h, regardless of whether they are defined in start.S. What does your u-boot-arm.h say about them? Amicalement, -- Albert. _______________________________________________ U-Boot mailing list [email protected] http://lists.denx.de/mailman/listinfo/u-boot
