May I ask why do you need floating point operations in a kernel? At
least, what sort of operations and why not move them upwards.
We are doing floating point operations in one of the device drivers as
part of the BSP - to perform buadrate calculation, to be specific, which
involes inverse operations and using roundf().
understand that the math library functions are not part of standard C
library and has to be linked using "-lm". So I include "LD_LIBS +=
-lm" in
the custom .cgf config file but this doesn't seem to work. I think
this has
to be linked in a proper order. Could someone help with this?
Heres the custom config file:
include $(RTEMS_ROOT)/make/custom/default.cfg
RTEMS_CPU = arm
LD_LIBS += -lm
CPU_CFLAGS = -march=armv7-m -mthumb
CFLAGS_OPTIMIZE_V = -O0 -g -mfloat-abi=hard -mfpu=fpv4-sp-d16
Thanks and Regards,
Sudarshan
