RTOS/AM5728: DSP audio loopback stack corruption

Tool/software: TI-RTOS

Hi,

I'm using the Beagleboard-x15 and trying to run the EVM572x audio loopback example (on the C66x)  included in the RTOS SDK.  I'm seeing stack corruption using that example when I add an array in main.  I was able to run the pdkProjectCreate.sh scrip to generate the project, and imported that into CCS to run. 

I then added an array into main so my main function looks like (the highlighted code is the only code I added):

volatile int emuwait=0;
int main(Void)
{

while(emuwait);

configureAudio();

McaspDevice_init();

int temp[256];
int i = 0;
for(i = 0; i<256; ++i)
temp[i]=i;

configMcASP_SocHwInfo();

Aic31_init();

Log_info0("\r\nAudio Sample Main\n");

BIOS_start();

return 0;
}

When the audio is running, the temp array gets corrupted.  Does the RTOS expect you to not create any data on the stack in main before the OS starts?
