Hello,

I have run into an unexpected problem where suddenly flashing my device with CCS when debugging now wipes my Non-volatile storage. In the past this never happened, so I'm not sure what's changed now to create the problem.

For my access to the NVS, I'm using the TI Non-Volatile Storage driver interface, and addressing one page (0x1000) of memory starting at 0x1b000.

This problem seems to only exist with CCS. I can flash the device with uniflash and I don't see the same effect.

In my debug options for CCS the Flash erase settings are set to "Necessary settings only (Retain untouched content within sector)" and I haven't changed this myself at all.

Any ideas?

Hi Craig,

Which exact versions of CCS and UniFlash did you try this on?

Thanks

CSS version is 7.2.0.00013

Uniflash is 4.2.0.1435

Important to note I haven't done any updates prior to this problem emerging. Only think I can think of is that I did briefly change the NVS section size to test something, but then changed it back.

I did have another issue earlier, actually, where I had to reinstall my XDS110 drivers because they would no longer work with my boards.

Thanks. I tried this out with my CCSv7.4.0 installation and didn't see any issue. I am installing CCSv7.2.0 to see if that makes a difference. Do you see this issue with any application you try to load to flash?

Thanks

I have two applications in the same CCS workspace (one CC1310 and one CC1350). Both use the NVS driver and both have their NVS sectors wiped when flashed in CCS.

Craig, can you provide the executable (*.out) file? If do not wish to share it publicly, please start a private conversation with me.

Thanks

Craig,

Thanks for the executables. I can reproduce the issue on CCS 7.2 and CCS 7.4. But the issue does not appear to exist in CCS 9.3. Can you try updating you CCS version?

Thanks

I've just noticed your response.

It's a risk for me to disrupt my development environment at the moment, don't want to potentially cause other unexpected problems. I'll try as soon as I have a bit more time to address any problems that might arise.

If you can install 9.3.0 (along with your existing 7.2 installation) just to test it out, that'd be great. 7.x is a pretty old version and there has been many bug fixes since that version.

Yep, CCS V9.3 seems to have fixed the problem, thanks!
