We are using an iMX6 based board, and we want to know how to best set the archetecture specific compiler flags.

 

  • Our builds are using the Linaro toolchain installed with LTIB, currently v 4.6.2.
  • We are using Sabre Lite's and iWave QSeven's until our custom devices are available.

 

Our current CFLAGS for these boards are:

  • CFLAGS_IMX6 := -march=armv7-a -mfpu=vfpv3 -mfloat-abi=softfp

 

Thanks,

-Rory
