My application is based on the audio_edma_c6747 demo project. I want to use a task to scan I/O for user interface keys. I have created a task using the DSP/BIOS config as below. But when I enable the clock: bios.CLK.RESETTIMER = 1; and try to sleep the task TSK_sleep(1000); the code crashes after about 4 seconds! Am I missing something or doing something wrong. If I keep a simple counter in the tsk instead of using the sleep function, it seems to work. But anything I do using the ticks ie:TSK_sleep() or TSK_time() Causes the crash ....
Any ideas.... thanks
------------------------------
bios.TSK.create("Keyscan_tsk");
bios.TSK.instance("Keyscan_tsk").order = 2;
bios.TSK.instance("Keyscan_tsk").priority = 1;
bios.TSK.instance("Keyscan_tsk").fxn = prog.extern("Keyscan_tsk_fxn");
bios.PRD.OBJMEMSEG = prog.get("IRAM");
bios.TSK.DRIVETSKTICK = "PRD";
bios.PRD.USECLK = 1;
bios.GBL.CLKIN = 24000;
bios.CLK.RESETTIMER = 1;
--------------------------------
My test task looks like:
static void io_run(void)
{
static int ledState = 0;
static Uns ticks = 0;
while (1)
{
TSK_sleep(1000); //sleep for 1 sec at 60mHz
if (ledState)
EVM_LED_on ( 0 );
elsE
EVM_LED_off ( 0 );
ledState ^= 0x01;
}
}
//-----------------------------------------------------------------------------
// Static TSK Function
//-----------------------------------------------------------------------------
int Keyscan_tsk_fxn()
{
io_run();
return 0;
}
