Hi:
when I use the floating point calculation in the wiced studio,and there are some compile errors as below.
Unknown symbol __aeabi_ui2d (err 0)
Unknown symbol __aeabi_dcmplt (err 0)
Unknown symbol __aeabi_ddiv (err 0)
Unknown symbol __aeabi_dmul (err 0)
Unknown symbol __aeabi_dadd (err 0)
Unknown symbol __aeabi_dcmpgt (err 0)
Unknown symbol __aeabi_dsub (err 0)
Unknown symbol __aeabi_i2d (err 0)
Unknown symbol __aeabi_d2uiz (err 0)
Unknown symbol __aeabi_d2iz (err 0)
I guess the reason is that the current the configuration of the wiced studio can't support the floating point calculation.
who can tell me how to configue the wiced studio to support the floating point calculation.
thanks!

I think this limitation is also caused by the lack of FPU in CM3, which is widely used in our BT ICs. A solution was suggested below:
