Hi all.
I'm trying to run a very simple (sample) program on DSP1 processor of the TDA3xx device.
The code is:
/*
* ======== main.c ========
*/
#include <xdc/std.h>
#include <xdc/runtime/Error.h>
#include <xdc/runtime/System.h>
#include <ti/sysbios/BIOS.h>
#include <ti/sysbios/knl/Task.h>
#include <ti/sysbios/knl/Clock.h>
/*
* ======== taskFxn ========
*/
Void taskFxn(UArg a0, UArg a1)
{
System_printf("DSP1: enter taskFxn()\n");
System_flush();
Task_sleep(10);
System_printf("DSP1: exit taskFxn()\n");
System_flush(); /* force SysMin output to console */
}
/*
* ======== main ========
*/
Int main()
{
Task_Handle task;
Error_Block eb;
System_printf("DSP1: enter main()\n");
System_flush();
Error_init(&eb);
task = Task_create(taskFxn, NULL, &eb);
if (task == NULL) {
System_printf("DSP1: Task_create() failed!\n");
BIOS_exit(0);
}
BIOS_start(); /* does not return */
return(0);
}
The problem happens when the program enters Task_sleep(10). The program enters this sleep and never leaves it.
I can see all prints till entering the sleep.
Following is the .CFG file:
var Defaults = xdc.useModule('xdc.runtime.Defaults');
var Diags = xdc.useModule('xdc.runtime.Diags');
var Error = xdc.useModule('xdc.runtime.Error');
var Log = xdc.useModule('xdc.runtime.Log');
var LoggerBuf = xdc.useModule('xdc.runtime.LoggerBuf');
var Main = xdc.useModule('xdc.runtime.Main');
var Memory = xdc.useModule('xdc.runtime.Memory')
var SysMin = xdc.useModule('xdc.runtime.SysMin');
var System = xdc.useModule('xdc.runtime.System');
var Text = xdc.useModule('xdc.runtime.Text');
var BIOS = xdc.useModule('ti.sysbios.BIOS');
var Swi = xdc.useModule('ti.sysbios.knl.Swi');
var Task = xdc.useModule('ti.sysbios.knl.Task');
var Semaphore = xdc.useModule('ti.sysbios.knl.Semaphore');
var Hwi = xdc.useModule('ti.sysbios.hal.Hwi');
var Clock = xdc.useModule('ti.sysbios.knl.Clock');

Error.raiseHook = null;

SysMin.bufSize = 0x200;
/*

*/
var loggerBufParams = new LoggerBuf.Params();
loggerBufParams.numEntries = 16;
var logger0 = LoggerBuf.create(loggerBufParams);
Defaults.common$.logger = logger0;

I'm using the following:
Compiler version: TI v8.2.3
XDCtools version: 3.50.5.12_core
Device endianness: little
Runtime support library: rts6600_elf.lib
Target: ti.targets.elf.C66
Platform: ti.platforms.simVayu
