Wrong flash memory size in st-link

[VolterPhase]

Hello,

I am using the STM32f107vct6 which has 256kbyte flash memory size. However, after connecting to MCU via st-link V2 and ST-link utility it shows me just a few pages of my flash memory size and the wrong flash memory size.

what is my mistake?

The ST-LINK Utilities are very OLD and DEPRECATED

Use STM32 Cube Programmer for most current software

The part could be mismarked. Perhaps intentionally to get a higher price. 

The die has more FLASH, a sub-set was tested in production, and burned in the OTP settings, the tools should be reading that 16-bit word to see size in KB, check that, check the description of this value in the Reference Manual RM0008
