I use -mcpu=3Dcortex-m4 -std=3Dgnu11 -g -DDEBUG -DUSE_HAL_DRIVER -DSTM32F44=
6xx  -Og
-ffunction-sections -fdata-sections -Wall -Wextra -fstack-usage
--specs=3Dnano.specs -mfpu=3Dfpv4-sp-d16 -mfloat-abi=3Dhard -mthumb -save-t=
emps
-ffile-prefix-map=3D/home/runner/work/Nyx_Simulink/Nyx_Simulink/Code=3D.
