>>Friends, there is a MCU (STM32F103VBT6) on it, I need to read the firmware inside and install it on another board. With which ST-LINK can I do this, please help.
If the STM32 is not protected you can read via the SWD/JTAG connection, ie PA13:SWCLK, PA14:SWCLK, GND, and VCC/VTARGET(Pin1)
STM32 Cube Programmer can read and save content to a file, either .BIN or .HEX
Read from 0x08000000, Size 0x20000 (128KB)
Then move to destination device, an from programming tab/pane set the address and select the file and the program, and optional verify.
Protected devices (Read Out Protection) will preclude the recovery of a firmware binary
ST-LINK/V2, V2-1 or V3 would work for STM32F1 devices. ST-LINK Utility would also work for them, if the interface is easier to navigate
