Hi everyone!

I use stm32f103c8t6 and clone st-linkv2 when i try to debug my codes with stmcubeide i had a lot of errors. Like connection error or debug path etc. I cant solve it. When i use MDK-ARM code is working but i cant get any data. Please help!

For clone products, we can't garantie anything. I suggest you to contact one of our distributors (you can find them using the filters on this link) and get genuine products. 

Best Regards.

Hello @AnilKose 

To have a working product. You just have to buy genuine STM32 MCU and ST-LINK.

Best Regards.

        Hello @AnilKose ,

        As ST we cannot support "cloned" products. Maybe you need to find an answer somwhere on the net or contact the manufacturer?

        Many of STM32 users here in the community and outside faced issues with a such contrefeit products including cloned/copied STM32 chips.

        Thank you.

            Indeed, it's not nice to use clones. But anyway as you're in a hurry: I came across a whole batch of clones which had 100 Ohms series resistors in SWCLK and SWDIO lines (a bit high, but not the primary obstacle) and with 1k2 Ohm pull-down and pull-up on SWCLK and SWDIO, respectively. Removing the 1k2 pull-down on SWCLK cured the problem.

            https://www.mikrocontroller.net/topic/515218

            The symptom was unreliable connection, sometimes ok for a few seconds, then breaking reapeatedly, parity errors ...

            So, check for sensible resistor values.

              Indeed, to be fair, I have used clones in the past and they have worked.

              Another thing to beware of is that clones which look identical might have different pinouts!

              And some users have reported that the RST (Reset) does not work for STM32 (only STM8):

              A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.

                Clones (I mean of the type shown in the pictures andrew posted) also do not provide a SWO pin (without modding) needed for "Serial Wire Viewer" (SWV) debug functionality with CubeIDE, which is a very useful feature to have during development.
