Nucleo F103RB - Strange Flash Size

Hi,

i bought some Nucleo F103RB Boards and designed a circuit board for the Nucleo to drive my LEDs throught Bluetooth.
The prototype with airwires worked perfectly, but know i tried it with my circuit and if i plug the Nucleo on my circuit i got strange behaviour in flash sizes.
If i try to flash an image it cannot verify.
st-link showed my everytime i run it a different flash size, the sram and page size kept.

Here is a sample output:

Anyone got the same strange behaviour of this? I dont know where it belongs to.
