TMS320F28069: Problems flashing TMS320F28069 by JTAG using TI C2000-GANG Programmer

Andy,

1. How are the boot mode pins configured?  Did the customer try wait mode?

2  See if this helps for Error 69: https://e2e.ti.com/support/microcontrollers/c2000/f/171/t/655817?TMS320F28075-Differences-between-hardware-c2000-gang-programmer- 

3. What is the C2000 GANG hardware revision that the customer is using? 

4. What is the clock configuration that they are using with GANG?

I notified Elprotronic to look in to this post.  They will get back to you.

Thanks and regards,

Hi Vamsi,

Reply is as follows:

1. How are the boot mode pins configured?  Did the customer try wait mode?

    -> The current Boot mode is GetMode, can I ask C2000-GANG can directly replace XDS-100v2? Because customer use the XDS-100v2 pin are setting to GetMode, Customer will try wait mode.

2  See if this helps for Error 69: https://e2e.ti.com/support/microcontrollers/c2000/f/171/t/655817?TMS320F28075-Differences-between-hardware-c2000-gang-programmer- 

   -> Customer use extern DC power supply to test now

3. What is the C2000 GANG hardware revision that the customer is using? 

    -> Ver 1.04 

4. What is the clock configuration that they are using with GANG?

    -> 10MHz

Thanks,

Andy

Andy,

Thank you for the info.  It will help for Elprotronic to debug.  

What did customer program for OTP_BMODE for get mode?

I spoke to Elprotronic on this and they are evaluating a JTAG communication startup issue.

Andy,

Did the customer try wait-boot?  Is this resolved now?

Thanks and regards,

Hi Vamsi,

We try setting boot mode to Wait mode can fixed the issue, but customer PCB default is setting to GetMode , Customers do not want to change the hardware design , You have any suggest to programming with C2000-GANG by GetMode?

Thanks,

Andy

Hi Vamsi,

But we tested that TI XDS100v2 can be 100% programming the TMS320F28069  in Get Mode, the C2000-GANG can't use Get Mode.This is where we cannot understand. Why is there a difference between TI XDS100v2 & C2000-GANG for the boot mode?  

Thanks,

Andy

Andy,

When you say XDS100v2, you mean using XDS100V2 with CCS or UniFlash - correct?

Thanks and regards,
Vamsi

Hi Vamsi,

      Yes, We using XDS100V2 with CCS & UniFlash to testing.

Thanks,

Andy

Andy,

In case of CCS/UniFlash, I think multiple connection attempts are made after a failed emulation connection.  This helps to sneak in and make a reliable connection between two resets.  I can check with our CCS team and confirm.  

Maybe GANG is not doing this.

Thanks and regards,

Hi Vamsi,

Please help to check with CCS team and confirm.

And can TI help pass this information to Elprotronic and add this function to C2000-GANG GUI (multiple connection attempts are made after a failed emulation connection), because WaitMode requires additional GPIO pins, and these pins are not connected to JTAG 14 pins, and  need to switch back to GetMode after the programming is completed, increasing the programming work.

Thanks,

Andy

Andy,

Ok, let me check with the CCS team and get back to you.

Thanks and regards,

Vamsi

Andy,

I am working with CCS team on this.  Corresponding expert is out of office.  Initial analysis shows me that CCS does attempt more-than-once to establish a connection. 

I will loop in GANG expert with CCS expert to see if GANG can be enhanced for the same.

However, I can't keep the thread open that long.

Ideal way is to do flash programming on a fresh part in wait mode.  Since this is an enhancement discussion, I would like to close this thread for now.  You can open a new post for the follow-up of this thread in couple of weeks from now.  Does this sound good?

Thanks and regards,

Vamsi
