Select Custom CPU

1. Click Add button in the System Configuration dialog.

2. Click Configure button in the SoC dialog.

3. Select Custom from the drop-down menu.

4. Select CPU Family from the drop-down menu.

5. Select CPU from the list and confirm.

Target IP - Configure the Target IP to match the target where the application is executed.

Host type - Select the host:

• • Linux - Target where application and GDB server is running GNU/Linux operating system
  • ST Micro
  • Unknown

Use step prediction -  This option should be used when GDB Server doesn’t support code stepping. With this option enabled winIDEA takes care of code stepping.

Signals - Signals that can occur in the operating system.

Edit - Open the Signal dialog and configure following setting:

• • Name - Select a meaningful name.
  • CPU stop - GDB stops program execution when signal occurs.
  • Pass to program - GDB passes the signal to the application.

Application - Path to application executable on targets file system. This option is relevant only when GDB server is started from winIDEA.

Port - Port number where GDB server is running on target. If you are using winIDEA to start the GDB server, this will be the port that will be used.

Server:

• • Already running - GDB Server is already running on target. winIDEA just connects to GDB Server in this case. SSH and Simulator are in this disabled which is indicated in corresponding tabs.
  • Start via SSH - GDB Server on target is started by winIDEA over SSH communication protocol. In this case you will need to specify Application Path and SSH Connection parameters, which are described later in this chapter.
  • Start simulator executable - GDB Server on target starts with the simulator

1. Open View menu / Workspace / Terminal

2. Click Options button in the Terminal Window toolbar

3. Select Debugger option from the drop-down menu in the Terminal tab

Terminal Window display

Port - Port number where SSH server is running on target (usually port 22).

User name - User that winIDEA will use to log in to target over SSH and start GDB Server. Selected user should have rights to start GDB Server and execute application on target.

Authentication - Method used for user authentication when winIDEA tries to login to target over SSH.

• • None - No authentication required.
  • Password - winIDEA will use password of a user when connecting to target over SSH.  winIDEA will prompt for password when connecting to the target.
  • Private key - winIDEA will use private key authentication when connecting to target over SSH. winIDEA will prompt for private key pass phrase when connecting to the target.

Private key path - This option is relevant when using private key for authentication. Set this to path to private key file used for authentication.

In order to get the necessary debug info, you will need to specify the download file (.elf in the example above):

1. Open Debug menu  / Configure Session / Application tab.

2. Click Add button to open Application dialog.

3. In Symbol Files tab click Add to specify the download file.

Add - Click the button to add watchpoints from the Watchpoint configuration dialog:

Evaluate - Select watchpoint type:

• • Symbol - Select the symbol from the Symbol Browser dialog by clicking the ''...'' button.

• • Address - Type in address and size.

Type - Select access type: Any, Read, Write.

Use condition - If checked configuration of Hit count and Expression is enabled.
Each time the watchpoint is passed the expression (if present) will be evaluated and if it evaluates to true, it will count as one more hit. When the watchpoint is counted for as many times as specified in the Hit count, watchpoint will be hit and the program execution will be stopped.

1. Open Debug / Configure Session / SoCs tab and click Add button.

2. In Startup tab enable Run until option and select the application entry point function by clicking ''...'' button.

3. Enable Perform these actions also after Debug/CPU Reset option.
