PSoC 6 MCU

[MeSh_3749161]

We are trying to use hard FPU in PSoC 6, but in core_cm4.h FPU requires setting __SOFTFP__ into 0u:

however, it seems PSoC creator is using soft FPU by default:

In this thread, GeonaM_26​ has explained how to make new Makefile to change softfp into hardfp:https://community.cypress.com/thread/32197?q=Using%20hard%20FPU

but, this requires compiling the whole project outside of PSoC creator. Is there any way to change this parameter without manipulating a Makefile?

You can use the ModusToolbox tool instead of PSoC Creator. That configuration can easily be changed in a Eclipse based environment.

However, the tool does not support UDBs yet, in case you are using it.

It seems we need to eventually switch to Modus ToolBox ; however, we actually do use UDB in our project. Do I have to use arm gnu toolchain to compile the make file? I have tried it and it is giving me errors at time of make:

Export/prebuildCortexM0p.sh

make (e=-1): Error -1

make: *** [prebuild_CortexM0p] Error -1

Ensure that you follow the steps in enabling hardfp psoc 6​

Could you share the PSoC Creator project to recreate the issue at our end?
