Identify the Hardware
Initially, ensure that the target hardware is specified correctly in DS-5 Debugger. The debugger needs to know which processor or SoC is being used. Go to the "Configuration" panel and check if the right target is selected.
Verify the connection settings in DS-5 Debugger. This includes checking the JTAG frequency, the type of connection (e.g., DSTREAM, ULINK), and ensuring that drivers are installed correctly on your development machine.
Update and Verify Debug Configuration
Explore the possibility of the debugger configuration files being outdated or incorrect. You can update the DS-5 Debugger's configuration by downloading the latest configuration files for your target hardware from the ARM's official resources.
Open the "Debug Configurations" dialog in DS-5 and ensure that the settings match your target architecture. If necessary, create a new debug configuration by clicking "New launch configuration".
Check for Software Conflicts and Errors
Ensure there are no other applications accessing the debugger's connection to the target hardware. Close any conflicting applications or debugger instances that might be accessing the same target.
Open the debugger console in DS-5 and look for any error messages that might indicate the nature of the hardware recognition problem. Typical errors might relate to incorrect configuration or cable issues. For instance:
```plaintext
Failed to connect: Cannot identify target hardware.
```
Based on the error message, look for solutions specific to the issue encountered. Consider updating the debugger software or checking if there are patches available that address specific hardware recognition issues.
Examine Connection Interface and Cables
Debugger connectivity can be hindered by physical issues. Inspect cables and connectors for any visible damage or loose connections. Try replacing them to rule out hardware-related problems.
Verify the integrity of the board connections, ensuring the target board is powered on and functioning properly. Troubleshoot the physical setup meticulously.
Utilize Proper Initialization Commands
DS-5 might require specific initialization commands to recognize the target hardware. These can typically be found in the user's manual or provided by the silicon vendor.
You may input these initialization sequences via the DS-5's initialization script:
```plaintext
script
// Insert initialization sequence here
```
Ensure that this script runs before any connection attempt is made.
Custom Script Check
In cases where a custom initialization script has been previously set up, double-check that it doesn't contain any errors. Scripts that misconfigure the board can lead to recognition issues.
Review any custom scripts for syntax errors or misconfigured parameters.
Consult ARM DS-5 Documentation and Support
If issues persist, review ARM's documentation related to the version of DS-5 you are using. Specific version updates might address bugs causing the recognition error.
Engage with ARM support or communities. Other developers may have faced similar issues and could offer solutions or workarounds.
- If a custom board is used, provide ARM support with accurate specs and configurations used during your debugging process for more tailored assistance.
