I'm starting with the VDK in EZKIT BF533 and I'm taking the only example available with the visual dsp: the pipelined audio.
With the example you can switch from one channel or two stereo (quadraphonic mode). It's working perfectly.
However, seeking my future application, it is necessary that the variables of the threads are in external memory. Thus, in the project options I enabled the external memory and put the system heap in L3.
When this is done, the example does not work, the audio input not output (quadraphonic mode only).
What would be the problem? Some configuration in the example should be changed?
