TMS320F28030: Flash programing config

I can program the flash. To boot from flash I short the TRSET.
the sequence of steps:

1. power on system
2. GPIO34 = GPIO37 = 1 & TRSTn = 1
3. wait ~5sec's
4. short TRST to Ground GPIO34 = GPIO37 = 1 & TRSTn = 0.
5. Boot from flash and excludes source code.

6. Send test script Pass

Test 2

1 short TRST to Ground  GPIO34 = GPIO37 = 1 & TRSTn = 0

2.  power on system 
3. wait ~5sec's 
5. Send test script Fails

 In case 1  shorting  TRST  to ground  5 sec after power is applied,  pass.

 In case 2 shorting  TRST  to ground before power is applied,  fails

.

thanks
Is this normal behavior?

thanks

Hi the emulator is not connected, I need to get through this issue  may I contact you directly

JW,

No, this is not normal behavior.

Case 2 should be able to run your application code in standalone mode. Case 1 really doesn't make sense to me. Also, I don't see why you have to wait for 5 secs. Is 5 secs a timeout condition before we call a test failed?

Regards,

Manoj

the time is arbitrary, I can wait 5 sec or 10mins the results are the same.

 starts in stand alone mode
"Set weak pull-up on GPIO34 = GPIO37 and weak pull down on TRSTn = 0", the codes does not run correctly

Starts emulation mode  then transition to stand alone mode
"Set weak pull-up on GPIO34 = GPIO37 and weak pull down on TRSTn = 1", wait, the codes runs correctly.

In all cases  the emulator is disconnected
 
suggestions where to look

Hi, the TRST is being read after startup, Can the issue be in the CMD file?

Using the debugger it executes as expected

Does the  In scripts "EMU mode"  dose the EMU mode need to be selected?

Do I need to be concern about the GEL See below:

 if (GEL_IsInRealtimeMode())   /* If in real-time-mode */
    {
    }
    else    /* Put device in C28x mode */
    {
         C28x_Mode();
    }
    Unlock_CSM();
    Device_Cal();
    CLA_Clock_Enable();             /* Enable CLA clock - allows the debugger to set CLA breakpoints after reset */
//  Uncomment for the desired boot-mode on a reset:   
//    EMU_BOOT_SARAM();           /* Set EMU Boot Variables - Boot to SARAM */
  //  EMU_BOOT_FLASH();           /* Set EMU Boot Variables - Boot to flash */
