[Lakshmikanth Satyavolu]

Hi All,

I have modified ARM FB ABI type preprocessor macro to "soft" to optimize power consumption in my saadc routines. But I am seeing below error while compiling. I have checked nRF_Crypto_backend_oberon folder preprocessor options to see if it inherits soft option from common configuration. It is also showing ARM_FB_ABI as soft. But still my code is not built. 

../../../../../../external/nrf_oberon/lib/cortex-m4/hard-float/liboberon_3.0.1.a(ocrypto_ecdh_p256.c.obj) uses VFP register arguments, Output/Release/Exe/ble_app_hrs_pca10040_s132.elf does not

Is there anything I need to take care of? Please let me know. 

Best

Lakshmi

Hi Lakshmi,

You need to link in the "Soft-float" variant of the library from \external\nrf_oberon\lib\cortex-m4\soft-float when you change the ABI to "soft".

It worked. Thanks Vidar.
