CubeMX F4 projec with freertos will not build cos of asm instruction Posted by stf12 on 2015-04-21 08:43 Hi all, try to change these project settings in the MCU Settings section: Floating point hardware : fpv4-sp-d16 Floating-point ABI : hard And make a Clean Project before rebuild. STM32F4 has a powerful flaoting point hardwere support ... so why don’t use it?! ;-) Regards, Stefano
