I am new to embedded and stm32cubeide, self teaching so I can use it in a group project related to university studies. After purchasing a "blue pill" from aliexpress, I realized I might of bought a clone chip. I followed the instructions shown here (stm32 community site), and I'm still getting an error that the ide cannot verify my ST device.
Here is what I have as output:

I see in the console "undefined debug reason 8 - target needs reset", is this the problem? If so what can I do to solve this? If not, then what do I do other than purchasing another board?
Below is my test Debug.cfg, in case I need to change something in there:
# This is an genericBoard board with a single STM32F103C8Tx chip
#
# Generated by STM32CubeIDE
# Take care that such file, as generated, may be overridden without any early notice. Please have a look to debug launch configuration setup(s)

set WORKAREASIZE 0x5000

Thanks
I found some FT232 that I had in spare, and I was able to program the chip using the stm32 programmer software and a generated hex file from the ide.
I'll use this method if ever I run into cloned chips and the st link v2 if ever I get a genuine board.
