I now this is something simple but I haven't been able to find an answer to my problem, also this is the first time that I am trying to use this line of mcus and I have been trying to solve this problem for a few days, so any help is appreciated.

I am using cubeMX to generate code to use the board as a usb HID and am using sw4stm32 to write everything else. When I try to flash the mcu, using a st-link v2 I get this text:

Open On-Chip Debugger 0.10.0-dev-00015-gaaf1808 (2018-11-13-13:07)

I am trying to use this board: https://stm32-base.org/boards/STM32F103C8T6-Blue-Header and have the connections between the board and st link like this:

ST-link - Dev Board

swdio - pa13


SWCLK - pa14

3.3 - 3.3

I'm powering the board temporarily though the st link because I am just trying to flash it. also I tried flashing it with BOOT0 tide to GND, short on the jumper j6, and without the short but neither worked. can someone help me figure out this problem. Up to now I've only used Microchip MCUs and I haven't run into this kind of problem.
