Hi,

I set on-chip flash key by ccs12 when I debug a TI's routine, but now I can't enter debug.

I don't know what's going on.

Thanks & Regards,

You also need to unlock the device with same key.

Ben,

If you use the same key for locking and unlocking it should work. We use it all the time. Please take a look at this and go through the full discussion on locking the device:

Thank & Regards,

Hi Ben,

Please try to run any gpio example from C2000Ware, and check if you still encounter same behavior?

in the '.text' section has executable code. Please refer to this link for details on Linker command File.

Hi Santosh,

Yes, It still behave like this:

I'm afraid that I have to clear the chip, because the program doesn't matter. Is there any way I can do that?

Best Regards,

Ben

Ben,

Just to confirm, when you put the board in 'WaitBoot' mode, then you are able to connect the target?

Can you open the GEL file? It is located in the CCS installation file.

C:/ti/ccs1200/ccs/ccs_base/emulation/gel/f28069.gel

Make a copy of the file, before editing it.

Now open the file in Text editor.

and add the Keys same as you mentioned earlier.
