Hello,
i'm using stm32f103c8t6 and IAR as IDE and recently I was no longer able to to load the code using IAR, as error message i had "Fatal error: ST-Link, no MCU device found ".
and when i use STM32 ST-LINK Utility i can acces to the MCU and i can erase the flash (in order to connect the the stm32 to the ST-LINK Utility i have to press the reset button then press connect button of the ST-LINK Utility then release the reset button of the MCU )

can anybody help fix that please
and thank you
