I do not think you have conclusively proved it is the debugger that is at fault.

The ''stm32f303'' is just a STM32F3 embedded processor. I did not find a specific

evaluation board for this part - so I do not know what debugger you are referring to.

Is a ST-Link (in a little white plastic case)

Ok, so what boards is this, which USB connection are you using, and what debugger are you talking about?
