I am trying to move the Block and Sample based examples for the Sharc ADSP-21479 to a VDK framework.
In my initialisation thread I call the main() function from the examples to setup the ISR...
initPLL_SDRAM(); // initialize the PLL and SDRAM controller
// Initialize DAI because the SPORT and SPI signals
// need to be routed
// This function will configure the AD1939 codec on the 21479 EZ-KIT
// Unmask SPORT1 RX ISR Interrupt
but the ISR routine process_AD1939_samples is never called.
Reading the documentation I noticed that signal.h is not supported by VDK, is this my problem?
How can I setup the ISR for receiving audio from the DAC in a VDK app?
Do I need to add a New Interrupt under the Kernel tab?
