[C66xx_0] ti.sysbios.knl.Semaphore: line 290: assertion failure: A_overflow: Count has exceeded 65535 and rolled over.

Hi Weichun --

Some code in your application is calling Semaphore_post() many times without any calls to Semaphore_pend().   This is causing the semaphore count to grow until it overflows.   This points to a logic problem somewhere in your app.

The code that is catching the problem is in <bi9sinstalldir>/packages/ti/sysbios/knl/Semaphore.c:

You can edit this code and put a b/p at near the assert() to see if you can catch it before the assert.

Use

"BIOS.libType = BIOS.LibType_CUSTOM"

in your .cfg and this will rebuild BIOS with your code change.

Void Semaphore_post(Semaphore_Object *sem)
{
    UInt tskKey, hwiKey;
    Semaphore_PendElem *elem;
    Queue_Handle pendQ;

    /* Event_post will do a Log_write, should we do one here too? */
    Log_write2(Semaphore_LM_post, (UArg)sem, (UArg)sem->count);

    pendQ = Semaphore_Instance_State_pendQ(sem);

    hwiKey = Hwi_disable();

    if (Queue_empty(pendQ)) {
        if (((UInt)sem->mode & 0x1) != 0) {   /* if BINARY bit is set */
            sem->count = 1;
        }
        else {
            sem->count++;

            // DEBUG
           if (count == 0) {
                asm(" nop");           // put a b/p here and look at stack backtrace and semaphore handle.
           }

            Assert_isTrue((sem->count != 0), Semaphore_A_overflow);
        }
