(CCES) software development tool chain is required for a full evaluation of this hardware platform. The EV-21593-SOM can also be used in a limited standalone mode while not plugged into a SoM Carrier such as the EV-SOMCRR-EZKIT or EV-SOMCRR-AUTO . The standalone mode is useful for evaluat- ing the CCES Software Development Tools and benchmarking software algorithms that do not require peripheral I/O. -

ICE-2000 to for debugging. When the EV-21593-SOM is connected to a carrier board the Debug Agent on the carrier board can be used. To use this Debug Agent, all postions on SW1 (on the carrier board) must be in the ON position. If an emulator, such as the ICE-1000 or ICE-2000, is used instead all postions on SW1 must be in the OFF position. -
