GNU Arm Embedded Toolchain

Cortex-A support

Asked by Shawn Heo

Hi,

It seems that this project doesn't support Cortex-A processor. Can you recommend the best way to get Linaro arm-none-eabi toolchain for Cortex-A processor? Actually, I can't understand how people build Linaro u-boot for Cortex-A based board (e.g. Versatile Express).

Thanks.

Hi, Shawn,

Thanks for exploring this toolchain. This project is targeting Cortex-R/M
processors. But it just "works" for Cortex-A without optimization. Say if
you build a bare-metal program with this toolchain with -mcpu=cortex-A15,
it will has following problem: Compiler doesn't include latest optimization
for A15, and library it links is only for armv6t.

To work better on Cortex-A, please follow Linaro GCC that may deliver a
bare-metal toolchain for Cortex-A soon. Michael Hope is the one who can
give you more information about it.

Thanks - Joey
