Hi,
I have brought 2 STlinkV3MODS. I have soldered wire at CN5 connector with 5+3 pin general connector to target the bluepill(not sure original or clone) the target MCU is STM32F103C8T6. when i select STlink at cube programmer shows error: debug authentication or STM32 target not found. Where as clone stlink V2 (usb dongle) type detected target MCU (cap1.jpg) Now question: 1) if cloned or fake chines STM32F103C8T6 is the cause?
2) i am waiting from supplier the original STM32F103C8T6 chip, and they suggest not use STlinkV3/V2 rather use Jlink.
3) How can we found which chip is original or fake? by reading chip id 0x414 can't confirmed the genuinity.
4) All the screen shot and pinouts are given.
Required solution: what is the cause for not connecting the blupill chip with original stlinkV3MODS
