Fatal error: C3903U: Argument 'neon' not permitted for option 'fpu'.

Alex_Chun 8 months ago

Hi

Im using cycloneVsoc (cortex-A9 duel core) with armcc v5.06.

I used to do --fpu = vfpv3 --cpu = cortex-a9 on makefile

Now I want to use neon instead.

Yet I can't use --fpu option to open neon.

Ive confurmed that this port does support the neon.

According to ARMCC v5.06 UG for uVision, --fpu don't have neon option.

Could you please tell me how to start/open it by makefile?

Thank you very much

Also, I should mention that if you wish the compiler to generate Neon instructions, you should add the --vectorise option.

Without this, it can still use libraries or asm code that contain Neon instructions.
