Cross-compiling issues

User Questions

Hi all,

I took a step back from my latest post and decided to deploy my MPC on a MCU that can handle dynamic memory allocation. Therefore, I still use TI’s TMS320F280049C. However, I am having trouble cross-compiling acados. Could you give me a brief explanation on what I have to do in order to successfully cross-compile acados?
I already tried to adapt the Embedded Workflow that you are providing within the acados documentation. But I seem to overlook something since the libs that are generated within this process don’t work for me. I believe that the reason for my issue lies within the Cmake-Toolchain file. I’d be thankful if you could give me some advice on the most important steps that have to be covered when cross-compiling acados.
Thank you in advance!

Best regards,
Leon

Hi Leon,

as you found here: Embedded Workflow — acados documentation
The cross compilation workflow is only documented for some dSpace architectures.
However, the main points done in these Toolchain files need to be done when cross-compiling for any platform.
Such as setting the:

  • compiler
  • linker
  • BLASFEO target
  • HPIPM target
  • additional C Flags
  • remove definitions that are set automatically by running cmake from your host system
    …

Maybe someone can help you more if you add some more specific information on what you tried, and where you are stuck.

Best,
Jonthan
