sorry, my fault -- forgot to rebuild the whole project. Everything works fine with enabled FPU (-mthumb -mcpu=cortex-m4 -mfpu=fpv4-sp-d16 -mfloat-abi=hard) On Wed, 15 May 2019 at 17:06, Ярослав Лещинский wrote: > if change to CPU_CFLAGS = -mthumb -mcpu=cortex-m4 -mfpu=fpv4-sp-d16 >

Re: fatal after a new source-builder update

yes, I know, I just checked that behavior is the same as before. With these flags -mthumb -mcpu=cortex-m4 -mfpu=fpv4-sp-d16 -mfloat-abi=hard I got error from linker: /home/midnight/rtems/toolchain/5/lib/gcc/arm-rtems5/7.4.1/../../../../arm-rtems5/bin/ld: error: o-optimize/test.exe uses VFP
