Hi ,
I am working on OMAP 3530 Processor (ARM Cortex-A8 processor+C64x DSP) based our own development kit. I am trying to enable dsplink in-order to make DSP to work.
I have followed the steps given in the http://ossie.wireless.vt.edu/trac/wiki/BeagleBoard_DSPLink web link. I could able to build and insert dsplinkk.ko file successfully. But while running the sample application i am getting below kernel panic errors.
