...D'opus_alloc(x)=NULL' -D'opus_free(x)=NULL' Secondly; With the "overide" directives above no dynamic memory allocation is supposed to happen. However, the following call chain (obviously)  cause a crash: opus_encode(..)-> opus_encode_native(..)->ALLOC_STACK->opus_alloc_scratch(..)->opus_alloc(..) Is this a bug or what am I missing here ? Any advise on how to get a basic encode/decode example working would be most appriciated. Thanks ! \Eric

In order to determine the optimum heap size requirements for my embedded C55xx design, I have used the following to get the encoder and decoder memory requirements: size = opus_encoder_get_size(config.channels); enc = malloc(size); error = opus_encoder_init(enc, config.Fs, config.channels, config.application); size = opus_decoder_get_size(config.channels);

NONTHREADSAFE_PSEUDOSTACK requires a working allocator. You should select either vararrays or alloca(). Both should work on any gcc-based Cortex-M toolchain. (For that matter, malloc() and free() should work fine too, unless you have other reasons to avoid them)
