CCS/TMS320F28069M: GUI Composer V2 and Target Possibly Paused

Stuart Baker

Part Number: TMS320F28069M

Tool/software: Code Composer Studio

When I click the run button, the GUI composer downloads my program to FLASH and presumably starts the application. However, the target behaves as if it is paused (does nothing). If I download the same *.out file using Code Composer Studio, then click resume, the target behaves as it is supposed to and runs the program (in this case starts a motor).

Is it possible that the GUI Composer is leaving the target in a paused state? If so, how do we ensure that it resumes?

Thanks,

Stuart

Stuart,

We have a theory on this one. We think that there is an extra reset happening that is causing the program not to run.

Could you try something?

If you go to
<user folder>\AppData\Local\Texas Instruments\TICloudAgent\loaders\ccs_base\emulation\gel

Open the gel file for F28069

It will have an OnTargetConnect() function that looks like this. Try removing that GEL_Reset() from the end.

OnTargetConnect()
{
if (GEL_IsInRealtimeMode()) /* If in real-time-mode */
{
}
else /* Put device in C28x mode */
{
C28x_Mode();
}
F28069_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 */
}
}

We think data in RAM is getting cleared and that is why the app isn't running.
