Hi, I've been seeing COM2:STMicro... port on my PC but after I removed some drivers and installed some, it disappeared. Still I can connect to the target using ST-LINK/V2-1 utility and I can debug the code using uVision5.
What software should I install more? Any help deeply appreciated.
(By the way, I learned that I can update the firmware of the board using ST-LINK utility and did that hoping this could make the UART print work with uVision program installed.. But now I cannot connect to the COM port using tera-term...)
ADD : I can find the COM port but printf is not working. Before I remove a driver (winusb from STmicro), the UART test program worked. I cannot reproduce it.
