  • Page 11: Licensing The On-board Integrated Debugger

    Licensing the on-board integrated debugger A 30-days evaluation period starts after the debugger (winIDEA) connects to the ITLPC2138 for the first time. Within the evaluation period, the user should request a regular license from iSYSTEM. Run the request wizard to obtain the license INIT string by pressing the ‘Request INIT…’ button in the ‘Hardware/Hardware/License’ tab.

  • Page 12: Use Of The On-board Integrated Debugger

    Use of the on-board integrated debugger Follow below instructions, in order to get a sample application running with “out of the box” experience. All jumpers are set in the default position during the final tests in the manufacturing. If winIDEA 2006 CD is not part of the package, please obtain winIDEA 2006 setup from your local iSYSTEM office or from www.isystem.com.

  • Page 13: Use Of An External Debugger

    Use of an external debugger An external debugger can be: • a JTAG debugger, which connects to a 20-pin P3 connector • a development tool supporting JTAG debugging and ETM (on-chip trace), which connects to a 38-pin Mictor P2 connector Setting up a debug environment for the first time •...

  • Page 14: Troubleshooting

    There was a case, where the code was programmed in the flash, which disabled the JTAG debug port shortly after reset. Due to the Philips implementation, the debugger cannot take over control over the CPU immediately after reset, but a part of code is executed before the CPU can be stopped by the debugger. In this particular case, the application disabled JTAG port before the debugger took control over the CPU and the debugger could not connect to the CPU at all.
