# Connecting Bare Metal Devices

You can connect bare metal devices to a development host to run and debug applications on them from Qt Creator using GDB or a hardware debugger. This enables you to debug on small devices that are not supported by the generic remote Linux device plugin. However, if the device does not have Qt libraries, you need a fake Qt installation.

The bare metal device type accepts custom GDB commands that you specify in the device options. You can specify the commands to execute when connecting using a particular debug server provider.

The following debug server providers are supported:

- EBlink
- J-Link
- OpenOCD
- ST-LINK
- uVision IDE

## Enabling the Bare Metal Device Plugin

To enable the Bare Metal Device plugin:

1. Select Help > About Plugins > Device Support > Bare Metal.
2. Select Restart Now to restart Qt Creator and load the plugin.

## Specifying Settings for Debug Server Providers

To create connections to bare metal devices using a debug server provider, select Tools > Options > Devices > Bare Metal > Add > Default. The available settings depend on the debug server provider.

### EBlink

EBlink is an ARM Cortex-M debug tool that supports squirrel scripting, live variables, and hot-plugging.

8. In the Type field, select the interface type.
9. In the Speed field, enter the interface speed between 120 and 8000 kiloherz (kHz).
10. Select the Disable cache check box to disable the EBlink flash cache.
11. Select the Auto shutdown check box to automatically shut down the EBlink server after disconnecting.
12. In the Init commands field, enter the commands to execute when initializing the connection.
13. In the Reset commands field, enter the commands to execute when resetting the connection.
14. Select Apply to add the debug server provider.

### J-Link

J-Link is a line of debug probes by Segger.

To specify settings for J-Link debug probes:

1. In the Name field, enter a name for the connection.
2. In the Startup mode field, select the mode to start the debug server provider in.
3. In the Host field, select the host name and port number to connect to the debug server provider.
4. In the Executable file field, enter the path to the debug server provider executable.
5. In the Host interface field, select the connection type, IP or USB, or use the default connection.
6. In the Target interface field, select the target interface type.
7. In the Speed field, enter the interface speed in kHz.
8. In the Device field, select the device to connect to.
9. In the Additional arguments field, enter arguments for the commands.
10. In the Init commands field, enter the commands to execute when initializing the connection.
11. In the Reset commands field, enter the commands to execute when resetting the connection.
12. Select Apply to add the debug server provider.

### OpenOCD

OpenOCD (Open On-Chip Debugger) is an on-chip debug solution for targets based on the ARM7 and ARM9 family with Embedded-ICE (JTAG) facility. It enables source level debugging with the GDB compiled for the ARM architecture.

To specify settings for OpenOCD:

1. In the Name field, enter a name for the connection.
2. In the Startup mode field, select the mode to start the debug server provider in.
3. In the Host field, select the host name and port number to connect to the debug server provider.
4. In the Executable file field, enter the path to the debug server provider executable.
5. In the Root scripts directory field, enter the path to the directory that contains configuration scripts.
6. In the Configuration file field, enter the path to the device configuration file.
7. In the Additional arguments field, enter arguments for the commands.
8. In the Init commands field, enter the commands to execute when initializing the connection.
9. In the Reset commands field, enter the commands to execute when resetting the connection.
10. Select Apply to add the debug server provider.

### St-Link

ST-LINK Utility is used for programming STM32 microcontrollers.

To specify settings for St-Link:

1. In the Name field, enter a name for the connection.
2. In the Startup mode field, select the mode to start the debug server provider in.
3. In the Host field, select the host name and port number to connect to the debug server provider.
4. In the Executable file field, enter the path to the debug server provider executable.
5. In the Verbosity level field, enter the level of verbose logging.
6. Select the Extended mode check box to continue listening for connection requests after after the connection is closed.
7. Select the Reset on connection check box to reset the board when the connection is created.
8. In the Version field, select the transport layer type supported by the device.
9. In the Init commands field, enter the commands to execute when initializing the connection.
10. In the Reset commands field, enter the commands to execute when resetting the connection.
11. Select Apply to add the debug server provider.

### uVision IDE

uVision is an IDE for developing applications for embedded devices. Applications can be debugged by using uVision Simulator or directly on hardware by using St-Link.

#### uVision Simulator

To specify settings for uVision Simulator or uVision St-Link Debugger:

1. In the Name field, enter a name for the connection.
2. In the Host field, select the host name and port number to connect to the debug server provider.
3. In the Tools file path field, enter the path to the Keil toolset configuration file.
4. In the Target device field, select the device to debug.
5. In the Target driver field, select the driver for connecting to the target device.
6. Select the Limit speed to real-time check box to limit the connection speed.
