ULINK USB-JTAG Adapter

The ULINK USB-JTAG Adapter allows you to debug and test programs and to program Flash memory on the MCB2400 Evaluation Board. To setup ULINK for Programming Flash within the µVision IDE, you must:

1. Connect the ULINK to the JTAG connector of the MCB2400 Board.
   Note that the red cable marks pin 1 of the JTAG-connector.

   

   Note

   • The Embedded ICE in the LPC2000 core is disabled when the device is in Power Down or Idle mode. ULINK stops working if your code puts the ARM device into Idle or Power Down mode. Therefore, do not enable either of the power saving modes of the LPC24x8 during the software development cycle in your application program.
2. Power up the MCB2400 Board.
3. Set the JTAG clock for your ULINK or ULINK2 adapter.
4. Configure Flash Programming in the Project — Options for Target — Utilities dialog.

   Click the toolbar button and select the Utilities tab.

   Set the Use Target Driver for Flash Programming option, then select the ULINK ARM Debugger as the Flash programming tool.

   
   
   
   

   Check the Update Target before Debugging option to ensure that the Flash ROM gets programmed whenever the debugger starts.

   Click the Settings button to open the Flash Download Setup dialog for the next step.

5. Configure the Flash Download Setup dialog.

   In the RAM for Algorithm section, set the Start: parameter to 0x40000000 and the Size: parameter to 0x0800

6. Click the Add button and select the LPC2000 IAP2 512kB Flash algorithm.

   

   Finally, click the OK button to save the Flash Download settings.

7. Download your application to Flash.

   Use the Download to Flash toolbar button to download the application program into the LPC2400 device.

   The ULINK-JTAG adapter can also be used for downloading and debugging application code in Flash ROM or in RAM of the LPC2400 microcontroller.
