I couldn’t eable FPU on both CW308_STM32F3 and CW308_STM32F4. For CW308_STM32F4, I just change some code in Makefile.stm32f4 like:
uncomment #FPUUSE=AAAAA and define -DARM_MATH_CM4 like CDEFS +=-DARM_MATH_CM4. But I got a problem like:
Could you tell me where else should I change more to enable FPU?
