STM32CubeProgrammer "Warning: The core is locked up"

[scaffire]

Hi, 

When programming STM32F303VCT6 chips using STLINK-V3SET programmers via a jtag connection and STM32cubeProgrammer I get "Warning: The core is locked up" and the board doesn't operate normally. Here is the log output:

Here's what I've tried so far

1. Same thing happens with known good standard versions of this PCB, so not the PCB/MCU
2. Updated STM32CubeProgrammer from V2.7.0 to V2.14.0, get the same error
3. Swapped out USB cable and ports, nope
4. Swapped out PSU to the PCB/MCU and confirmed the supply voltage, no issues here
5. Swapped out STLINK to a brand new one, no change
6. Restarted PC, Yeah, I did and no change.

What the heck else could the problem be?

Hello @scaffire 

I think you should use this post.(change the RDP option byte value to 0xAA)

Best regards.

Hi Issamos,

RDP was already set to 0xAA, but I tried changing it to 0xBB, applying it, and switching back to AA, but no dice. Same issue. Also, I can't find PCROP as mentioned in that post. I could try that if you could point me in the right direction.

Just a guess but possibly try "Reset mode" set to "Hardware".

It's working now... I think the issue was the Google Drive desktop shared folder that the firmware file was in. I've had issues with it in the past, so I decided to download the file from the Google Drive web interface to my hard disk this morning and it worked, but now it also works from the Drive desktop folder.
