I have been trying to compile a code using BSEC library which seems to be using hard float, is there a way to enable hard floating point during compile?
Have you set the project up as cortex-m4 -mfpu=fpv4-sp-d16 -mfloat-abi=hard or as cortex-m4?
You need to select the appropriate libalgobsec.a or just omit -mfloat-abi=hard or set -mfloat-abi=soft.
I’ve no clue which of the other options the nRF52840 supports tho’
