Hi,

Have you already disabled the JTAG mapping ?

RCC_APB2PeriphClockCmd(RCC_APB2Periph_AFIO, ENABLE);

GPIO_PinRemapConfig(GPIO_Remap_SWJ_JTAGDisable, ENABLE);

or

RCC_APB2PeriphClockCmd(RCC_APB2Periph_AFIO, ENABLE);

GPIO_PinRemapConfig(GPIO_Remap_SWJ_Disable, ENABLE);

Note that:

 - In first case you will be able to use only Serial Wire JTAG mode

 - In the second case you will not be able to use JTAG at all (so think about re-enabling the JTAG at the end of your program to be able to use it again...)

If you already did this, then, did you remove the JTAG pull ups resistors on your board?
