[meta-ti] omap3-sgx-modules-5.01.01.xx ONLY supports hardfp mode for now

[Ankur Tyagi]

Thanks for your response.

So it is worth trying with TUNE_FEATURE "hfp" and measure the performance.
Do I have to set TARGET_FPU as "hfp-neon" as default value is "vfp-neon"

Does it make sense to push this change upstream as well ?
