I just hit an issue cross-compiling the linux-linaro-2.6.37.git source. I'm seeing errors for arch/arm/mach-omap2/sleep34xx.S like:
Error: selected processor does not support ARM mode `smc #1' It appears to be related to commit: 98be69a ARM: omap3: Remove hand-encoded SMC instructions After doing a little searching, I stumbled across something similar from John Rigby: http://marc.info/?l=linux-omap&m=129118316614865&w=2 I "fixed" the problem on my system with this patch: diff --git a/arch/arm/mach-omap2/Makefile b/arch/arm/mach-omap2/Makefile index f6614a6..985bc89 100644 --- a/arch/arm/mach-omap2/Makefile +++ b/arch/arm/mach-omap2/Makefile @@ -68,7 +68,7 @@ obj-$(CONFIG_OMAP_SMARTREFLEX) += sr_device.o smartre obj-$(CONFIG_OMAP_SMARTREFLEX_CLASS3) += smartreflex-class3.o AFLAGS_sleep24xx.o :=-Wa,-march=armv6 -AFLAGS_sleep34xx.o :=-Wa,-march=armv7-a +AFLAGS_sleep34xx.o :=-Wa,-march=armv7-a$(plus_sec) ifeq ($(CONFIG_PM_VERBOSE),y) CFLAGS_pm_bus.o += -DDEBUG My question: Is this patch actually needed for cross-compiling our kernel, or is there some additional argument I need to pass to Make when building my kernel? FYI - My current command line looks like: make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- O=out V=1 uImage modules -andy _______________________________________________ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
