TMS320F28379S: device is reset during connect

Hello,

The issue most likely lies within the GEL file, specifically the OnTargetConnect() function. On every target connect, CCS will re-initialize the RAM and reset the CPU. These lines can be commented out. This file can be found in CCS at ccs\ccs_base\emulation\gel\f28379s.gel.

OnTargetConnect()
{

    // *(int *)0x5F412 =0x000F;      /* RAM INIT FOR M0/M1/D0/D1 Memory  */
    // *(int *)0x5F432 =0x003F;      /* RAM INIT FOR LS0..LS5  Memory    */
    // *(int *)0x5F452 =0xFFFF;      /* RAM INIT FOR GS0..GS15 Memory    */

    if (GEL_IsInRealtimeMode())     /* If in real-time-mode */
    {
    }
    else                            /* Put device into C28x Mode */
    {
        C28x_Mode();   
    }

    F28379S_Memory_Map();        /* Initialize the CCS memory map */

/* Check to see if CCS has been started-up with the DSP already */
/* running in real-time mode.  The user can add whatever        */
/* custom initialization stuff they want to each case.          */

    if (GEL_IsInRealtimeMode())     /* Do real-time mode target initialization */
    {

    }
    else                            /* Do stop-mode target initialization */
    {
        // GEL_Reset();                /* Reset DSP */
    }
}

Dear Matt, many thanks for your response! Funny, I tried to edit the GEL file you mentioned and commented out the GEL_Reset() by myself. But, unfortunately it did not change anything, still reseting the device. I suppose that the XDS100v3 does it by itself, but don't know.

Any other hints?

Hi,

I'm assuming all the steps on this thread were followed:  TMS320F2800156-Q1: Attach to a running target 

What version of CCS are you using?

Let me try on my own setup next week with my own F2837 device and XDS100v3 as well.

Best,
Matt

Hi Matt,

we use CCS V12.1.0.

Hello,

I am able to connect non-intrusively with an XDS100v2 on an F28377D unit.

These are the steps I followed: 

1. For OnTargetConnect() in the gel file (ti\ccs1281\ccs\ccs_base\emulation\gel\f28379s.gel):
   1. Are you commenting out the GEL_Reset() call?
   2. Are you commenting out the RAM initialization lines?
2. Go to View > Target Configurations. Right click the intended target configuration file (either under Projects or manually imported in User Defined) and select Properties
   1. Confirm "Halt the target on a connect" is unselected under Connection Options in the Program/Memory Load Options menu. Apply and close to save.
   2. Then right click the same target configuration file and select "Launch Selected Configuration".

Best,
Matt
