How to use simple floating point (Kinetis)?

Hi All


I am sorry about this simple question but CW has beaten me here..


I need to use a very small amount of single-precision floating point in a Kinetis project (part without FPU) but can't work out which libraries are needed to be added. I understand that "FP_fixedI_Thumb_LE_v7m.a" means that it includes just single precision IEEE32 - which seems fine (I prefer not to use the fastI since I need to exchange files with the format saved in them and I think that this faster format is not fully IEEE conform).


The problem is that this library requires support from other libraries as soon as floats are used. One missing reference is "__FSL__fp_handler_32_to_32" (but there are three or four others).

After studying the "EWL for Kinetis Development" help sections and trying a bunch of libraries that I could find as well as searching for any indication of where these are coming from I have to admit defeat.


Any clues?
