Page 11: 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 12: Use Of An External Debugger
Use of an external debugger An external debugger can be: • a JTAG debugger, which connects to a 20-pin P33 connector • a development tool supporting JTAG debugging and ETM (on-chip trace), which connects to a 38-pin Mictor P32 connector Setting up a debug environment for the first time •... -
Page 13: Troubleshooting
Troubleshooting The flash boot loader code is executed every time the CPU is powered or reset. The loader can execute the ISP command handler or the user application code. P0.14 is sensed on a rising edge on the RST (CPU reset) pin. If a low level is detected, ISP command handler starts and takes over control of the CPU after reset.
