I use the STM32L476 board witch Mbed Studio. I search the debug my program but i have a message error Following:

“pyocd.core.exceptions.TargetSupportError: Target type ‘stm32l476rg’ not recognized. Use ‘pyocd list --targets’ to see currently available target types. See for how to install additional target support.
Could not complete debug: Request reset failed with message: PyOCD failed to reset the target, please check the logs for more information”
