LAUNCHXL-F28P65X: error during Flash programming

Hi Joyce,

Please search for below questions in this FAQ: https://e2e.ti.com/support/microcontrollers/c2000-microcontrollers-group/c2000/f/c2000-microcontrollers-forum/1096194/faq-c2000-ccs-flash-plugin-and-uniflash 

• TMS320F28P65x Flash plugin usage notes
• In F28P65x flash tool GUI (CCS On-chip flash tool and/or Uniflash), why can't we choose the sectors that we want the flash tool to erase during the program load or standalone erase?  

As mentioned in the FAQ (see below snapshot), you need to check the protection values that you provided in the GUI:

Hi Vamsi,

Thanks for reply and we met another issue when using plugin GUI, by clicking configure clock to try to erase flash by sectors, these errors show up:

Does this mean the IC is locked/failed and could not be used? What else could we do?

Joyce

Hi Vamsi,

We've checked the protection part as you mentioned, show as below. But executing such erase, it showed erased successfully but still could not program.

What could be the possible reason? Seems didn't erase successfully actually?

Joyce

Hi Joyce,

I will be able to get back to you on wednesday. 

I am out of office currently.

Thanks and regards,

Vamsi

Hi Joyce,

Do you have further questions on this?

Can I close this post?

Thanks and regards,

Vamsi

Hi Vamsi,

Issue still here when using CCS to program into Flash:

What's next step to trouble shoot?

Joyce

Hi Joyce,

As per the console window messages, the error is related to Write/Erase protection.  Did you configure the protections in the flash plugin GUI as I suggested in my previous replies in this post?

Thanks and regards,
Vamsi

Vamsi,

Where to find the flash plugin GUI?

Joyce,

You need to connect the debugger to device to see the on-chip flash GUI.

Thanks and regards,
Vamsi

Vamsi,

I actually connected the debugger to the LP and the LEDs of power indicators are on. But didn't find the on-chip flash GUI through CCS debug view-->Tools-->onchip flash GUI, could you help provide a screenshot where the on-chip flash GUI is? Thanks

Joyce

Hi Joyce,

The snapshot you shared above shows that the debugger connection is disconnected.  

Once you connect, the same menu that you showed in your snapshot will reflect On-chip flash tool as well.

Thanks and regards,

Vamsi

Hi Vamsi,

We tried as you said using on-chip flash, still could not erase successfully (but console showed 'successfully'):

Compared with a normal LaunchPad, all goes to FF after erase:

What could be the reason?

Joyce

Hi Joyce,

Since I did not hear back from you, I am closing this post assuming the issue is resolved.

If you have further questions, please open a new post.

Thanks and regards,
Vamsi
