Audio Engine MP3 Decoder library linker settings

Question asked by Matti Sillanpää on May 22, 2017



I got ST audio engine library V2.0.2 from sales dudes. I'm trying to use the lib_mp3decoder_cortex_m4_v2.0.0 with my STM32F469I (-Discovery board), GCC and Eclipse with openstm32.


Question is, that what linker settings should I use?


My project uses compiler settings --float-abi hard and floating point hw fpv4-sp-d16. with this setup I just get VFP register argument error. I tried using the softfp for the float-abi, however the SpiritMP3DecoderInit -function deadlocks, so I assume the setup isn't correct yet.
