That looks like really old code from before we added 700 support to the
SM1000

Hi Jan,
Can you confirm which version of Codec2 that you're using? I was
trying to find where that code is and it doesn't appear to be in the
latest (https://github.com/drowe67/codec2/tree/main/src).
Thanks,

Hi,
I've progressed and the Codec 2 on STM32F4 already works somehow.
Now I wanted to use mode 700 b/sec, but found this *#ifndef*: I
can see CORTEX_M4 can not be defined - I am not able to run
MODE_700 on STM32? Or what should I do? thank you. Jan.

Hi Jan,
We run Codec 2 half duplex (along with a bunch of other modem
and FEC
code) on a 180 MHz stm32 and it works just fine in real time.
So your
expectations are quite realistic.
The build system we use for the stm32 is in
codec2/stm32/CMakeLists.txt, including C compiler flags (looks
like we
use -O3). We also use -O2 and -O3 on the build system for larger
machines and don't have any problems.
So it's probably some sort of configuration issue on your
build system.
A good approach is to start with something that works (e.g.
our stm32
build system), then maybe move to the IDE.
