cc1.exe: warning: -mfpu option does not match ADSP-SC594 processor What is the compiler option for enabling neon?

Hi,

Could you please try adding switch as -mfpu=neon-vfpv4 in the additional options.

However, please note that the -mproc=processor switch instructs the compiler to target the given Analog Devices processor.

This switch Sets the GCC ARM floating-point mode for ADSP-SC5xx processors with a Cortex-A5 core to neon-vfpv4. This is the equivalent of using the -mfpu= switch, and indicates that floating-point operations will be performed using the dedicated hardware.

If the -mproc=processor switch is not used, the compiler will default to using -mproc=ADSP-SC589 for Cortex-A5 and -mproc=ADSP-SC598 for Cortex-A55.

The switch is documented in the following section of the CCES Help:
ARM Development Tools Documentation > Cortex-A > Analog Devices ARM Toolchain Manual > GCC Compiler Additional Features
