C6run and file IO calls

kuyniu iyniuyn

I am using c6runapp to run code on a c6747 (with omap137). I have run a few of our projects successfully using this method.

Now I have an executable that uses file IO calls like fopen() to pass data to the DSP. I have successfully compiled and run the example code (cio_example) that does this. However, when I build and run my project, fopen is failing as it returns NULL. Furthermore, the errno is 0 indicating no failure.

The files are quite large (WAV files).

Am I doing something wrong? Any help appreciated, thanks.

The c6run package was not implemented by the compiler development team. So, we can't help you. Further, this product is no longer supported. Perhaps something from this old wiki category page will be helpful. Sorry to deliver such bad news.

Thanks and regards,

That's ok, thanks George. Just one further question - what do you recommend for building c674x DSP code since c6run is no longer supported? Is CCS the only option? Ideally we'd like to be able to SSH an ARM executable across to the board which is running Linux on omap, before having c6run push the code to the DSP.

I'm not an expert in this area. Consider using Syslink. If you have further questions about it, please post them in the BIOS forum.

Thanks and regards,
