error while uploading : open ocd child process termination reason:unplugged target or stlink already in use or stlink usbdriver not installed
Hi Again,
The “Additional drivers” are not drivers to install on your Linux but are the code generated in your project for the board to control USB devices. Anyway, this option is not what causing your problem.
Can you open a terminal then run “killall openocd” to kill every running OpenOCD connected to the ST-Link. Maybe one application is blocking access to the ST-Link.
By the way, do you have the same issue when running a debug session ?
