STM32G473RC - Error in Launch Sequence - when Flash File > 128kB
I guess I have found a Bug in the G473RC debug launch script:
I have a STM32G473RC MCU with 128k RAM and 256k Flash.
As long as the Flash File stays below the size of 128k all works fine. I can develop, test and debug with CubeIDE. As soon as the flash file becomes larger than 128k, I can no longer debug the Software, because the Launch of the debugger exits with an error message:

I have checked the MCU on the PCB: it IS a G473RC. I have checked the connection with Cube Programmer, it says the device has 256k Flash. The Linker Script is correct (128k RAM, 256k Flash) - it is orignal as CubeMX created it, i did not change it. The MCU in the CubeIDE Project is G473RC. The Project compiles without errors and warnings. So far all seems to be correct, which brings me to the asumption, that there might be a bug in the startup script.
How can I solve this? This is URGENT because this prevents me effectively from developing this project. Can I hack the startup scripts or something? Where can I find these? Thanks a lot!
What leads me to the conclusion, that this might be a bug in the IDE / the drivers / the setup script is, that when the size of the flash file is below 128k, the console output is:
Erasing memory corresponding to segment 0:
Erasing internal memory sectors [0 63]

As i have some experience with Flash memory, i asume there could be some wrong entries about the sector or cluster size. Where can I find those information, so i can hack them in order to get it running again? Thank you!
