STM32F103RCT6 Using Problem

Hi, all
Several days ago, I bought a devboard with a STM32F103RCT6 chip on it. According to the datasheets, that chip has 48 KB of RAM and 256 KB of flashrom.
However, when using the linux arm-gdb and the st-util and st-info, they say that the chip actually has 64 KB of RAM (so more then exptected).
(STM32F103RCT6 datasource: stm32f103rct6 chip datasheet
Using gdb (writing to memory and reading back from it), it does look at there is indeed 64 KB of RAM in the chip, ... but I do not find any reference to that chip with 64 KB of RAM.

Is there anyone has any idea what is going on here?


Which board exactly did you purchase? What is the hardware revision? The name and the hardware revision are printed on the board itself.

We usually use STM32F103RBT6 in our designs.
