If you are using BIOS you should use MEM_alloc().
I had problems when I used malloc along with MEM_alloc(). You have to be
careful when using the BIOS configuration...

Thanks for your help Jeff, I've created a 5sec timer that "simulates" the interrupt that you suggested.
In the timer function I am able to call the Mem_alloc and Mem_free with ...

If you're using DSP/BIOS, have a look at the MEM_alloc() function in the
DSP/BIOS API. Its third parameter allows you to specify the alignment.
