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?

[PATCH v2] device/linaro/beagleboard: Make adbd listen on network interface

adbd depends on this property to be capable of listening on network so that adb can connect to the device through network. Without this property set, adbd will only try to listen on the alternative usb gadget interface when it starts.

ICE when compiled for x86

by Khem Raj

Hi I am seeing an ICE while compiling gcc for i586 from linaro 4.5 branch This ICE happens in libstd++ when compiling with -march=pentium -Os If -march=pentium is not used then it compiles file and also -O2 works ok ios_init.c: In destructor 'std::ios_base::Init::~Init()': ios_init.c:15899:3: internal compiler error: in dwarf2out_begin_epilogue, at dwarf2out.c:2859 Please submit a full bug report, with preprocessed source if appropriate. See <http://gcc.gnu.org/bugs.html> for instructions. Is the error I get and if I revert r99474 the ICE goes away here is command to reproduce this error ./build.x86_64-linux.i586-oe-linux/gcc/cc1plus -Os -march=pentium ios_init.c and attached is the testcase to reproduce it Thanks -- -Khem
