Re: Wipy no float and math!

I'm think this cpu (cortexm4) support hard floats..
And if enable floating - fw increased with 5k - im dont think this is bigger - i'm have 45k free ram..
And with this flags code decreased with 1 or 2kb..
Im dont know what this flags did.. :)

Re: Wipy no float and math!

If ldflags dont have this flags : -mcpu=cortex-m4 -mtune=cortex-m4 - board freezes when using float numbers - why this flags not there?

Re: Wipy no float and math!

i'm only say that is possible to make fw with working floating and math.. And no need reinvent crutches for floating values.. And no official info about how compile floating support on this board - only "due to ram limitation... bla bla" - but this working and with 45kb ram - and we need change cfla...
