I am using stm32f103c8t6 with uart cable to connect it with stm32 cube programmer but come up the statement above. Any suggestion to fix this problem?

14:12:16 : Serial Port COM3 is successfully opened.

 14:12:16 : Port configuration: parity = even, baudrate = 115200, data-bit = 8,           stop-bit = 1.0, flow-control = off

 14:12:18 : Timeout error occured while waiting for acknowledgement.

 14:12:18 : Error: Activating device: KO. Please, verify the boot mode configuration and check the serial port configuration. Reset your device then try again... 

I did press reset button and placed my BOOT0 to 1 so i really have no idea to fix this problem.

Hello, i hope you found the solution to your problem. if not, try connecting the jumper connection of the 'boot-0' pin to the other side to put it in boot mode and upload your program. hope this helps
