Can't re-program STM32G030C8

[mark4444az]

I have tried everything I can think of to get part to program, I still get this:

The elf loader Sector Erase function fails.
Memory-Loader error
Error occured during erase operation!
Programming error @ 0x08000000!

I have tried STL CLI, JFlash-lite, JFlash, STM32Cubeprogrammer, always the same thng.

If anyone has any ideas I would be grateful.

Hello @mark4444az 

Is it a custom board? If yes do you have checked SWD connection?

If you are able to etablish a SWD connection with STM32CubeProgrammer, check option byte if the device is not protected (RDP ?)

I am using an STLink-V3Minie. I can look at the Option Bytes:

The Read/Write Protection is not checked so it is not on. Further, I have tried the JLinkSTM32 executable to reset options back to factory settings, said that  worked.

I do not see

I still am having no luck on programming.

did you try loading a bin or hex file ?

+ another chip ? maybe this one has a "problem" .

[mark4444az]

Yes, replaced the processor and programmed with gui and it's ok. The issue appears to be in my script file:

ST-LINK_CLI.exe -c SN=002000283431511737393330 -p RAD3.hex 0x08000000 -v -rst

When I use that it seems to brick the uP.

Found this:

1. Make PCROP_RDP checked, enable RDP level 1
2. Program option bytes.
3. Disable RDP.
4. MCU should be erased to 0xFFFFFFFF

That actually worked!  Found it on another thread.
