Beaglebone kernel needs to be built in Thumb2 mode to achieve fast boot times. Unfortunately, that build is broken under newer binutils-2.22 with the below Assembler error. The fix is to pass the specific -march=armv7-a flag to the Assembler to make it work. | arch/arm/boot/compressed/head.S: Assembler messages: | arch/arm/boot/compressed/head.S:127: Error: selected processor does not support requested special purpose register -- `mrs r2,cpsr' | arch/arm/boot/compressed/head.S:134: Error: selected processor does not support requested special purpose register -- `mrs r2,cpsr' | arch/arm/boot/compressed/head.S:136: Error: selected processor does not support requested special purpose register -- `msr cpsr_c,r2' | make[2]: *** [arch/arm/boot/compressed/head.o] Error 1 | make[1]: *** [arch/arm/boot/compressed/vmlinux] Error 2 Signed-off-by: Denys Dmytriyenko <denys@ti.com> Acked-by: Koen Kooi <koen@circuitco.com>
The official OpenEmbedded/Yocto BSP layer for Texas Instruments platforms.
This layer depends on:
URI: git://git.openembedded.org/openembedded-core
layers: meta
branch: master
revision: HEAD
URI: git://git.openembedded.org/meta-openembedded
layers: toolchain-layer
branch: master
revision: HEAD
There are known issues when using a toolchain with gcc-4.6 and binutils-2.22
from OpenEmbedded-Core, thus it is recommended to use toolchain-layer from
meta-openembedded with gcc-4.5 + Linaro patches and binutils-2.20.1.
The base BSP part of meta-ti should work with different OpenEmbedded/Yocto
distributions and layer stacks, such as:
distro-less (only with OE-Core), with Yocto/Poky, with Angstrom or Arago.
Please follow the recommended setup procedures of your OE distribution. When
using in a distro-less configuration, please add to your local.conf:
GCCVERSION = "4.5%"
BINUVERSION = "2.20.1"
