3.2.1.3 device
Selects a specific device J-Link shall connect to and performs a reconnect. In most
cases explicit selection of the device is not necessary. Selecting a device enables the
user to make use of the J-Link flash programming functionality as well as using
unlimited breakpoints in flash memory.
For some devices explicit device selection is mandatory in order to allow the DLL to
perform special handling needed by the device.
Some commands require that a device is set prior to use them.

device <DeviceName>
Example
device stm32f407ig
