Hello Steven,

A few questions.

• Is this a custom board design, or are you using a control card or LaunchPad? If not, can you confirm that you still get the same error when using one of these boards?
• Have you made any changes to the CCS Flash plugin settings (Debug Configurations > Target > Flash Settings)? In particular, ensure that "Erase and Program" is selected, and under Erase settings, Entire Flash is selected.
• Have you configured the DCSM/programmed the user OTP with any security settings? If so, you may need to confirm the address boundaries assigned to the security zone(s).

I would also be interested to see your output .map file, to inspect what symbols/code region is being affected at the sector 4 boundary.

Hi Ibukun,

Thanks for your reply. I have not made any changes to the plugin settings and "Erase and Program" is selected. "Entire flash" is also selected.

This is a custom board design and I am flashing with an external XDS100V3. Today I tried flashing the code on the TI launchpad and it worked no problem. I then flashed the code on my spare prototype and it also worked no problem. It appears this single device is damaged somehow.

I need to figure out the reason why this device memory suddenly stopped being able to be flashed as I am close to a production run. I think it is possible I turned off the power during flashing at one point. Do you think this could cause this kind of damage? Is there any possible procedure I can do to wipe/recover this device? 

Any other ideas? I am fairly certain my uC power supply setup is solid as I have previously been through a design review stage with TI on this PCB.

Many thanks!

Steven

Hi Ibukun, it works! An unsuccessful erase procedure was causing the problems. For some reason Uniflash was able to erase the device properly while the standard CCS tool/procedure was not. Strange as you would think they use the same erase process. Anyhow thanks for helping me save this device!
