Hi,

I wrote a multi-tasking executable on R5f,mcu2_0,but canot work.I don't know where the problem is,Following is my code.

extern "C" {

#include <app.h>

#include <app_ipc_rsctable.h>

#include <ti/sysbios/BIOS.h>

#include <ti/sysbios/knl/Task.h>

#include <utils/console_io/include/app_log.h>

#include <xdc/runtime/Error.h>

}

static Void appMain(UArg arg0, UArg arg1) {

appInit();

appRun();

printf("Task function appMain()------------>\n");

}

static Void func(UArg arg0, UArg arg1){

appInit();

appRun();

printf("Task function fun()------------>\n");

}

void StartupEmulatorWaitFxn(void) {

volatile uint32_t enableDebug = 0;

do {

} while (enableDebug);

}

static uint8_t gTskStackMain[8 * 1024]

__attribute__((section(".bss:taskStackSection")))

__attribute__((aligned(8192)));

int main(void) {

Task_Handle task1,task2;

Task_Params tskParams;

Error_Block eb;

StartupEmulatorWaitFxn();

Error_init(&eb);

Task_Params_init(&tskParams);

tskParams.arg0 = (UArg)NULL;

tskParams.arg1 = (UArg)NULL;

tskParams.priority = 8u;

tskParams.stack = gTskStackMain;

tskParams.stackSize = sizeof(gTskStackMain)/2;

task1 = Task_create(appMain, &tskParams, &eb);

tskParams.stack = gTskStackMain;

tskParams.stackSize = sizeof(gTskStackMain)/2;

task2 = Task_create(func, &tskParams, &eb);

if (nullptr == task1) {

BIOS_exit(0);

}

if (nullptr == task2) {

BIOS_exit(0);

}

BIOS_start();

return 0;

}

When executed, the error is:
