Embedded Target for OSEK/VDX

Tutorial 3: Downloading the Application to RAM
via SingleStep

In this section, we will download the osek_mrate.elf file (generated in the previous tutorial) to RAM on the target system.

We assume that the target system is a Phytec PhyCORE-MPC555 board. We will use the SingleStep debugger to download the generated osek_mrate.elf file to RAM on the target system, via the BDM port on the target board. We will then initiate a debugging session, set breakpoints, and verify real-time operation of the program.

Note    The SingleStep options and user interface screens discussed below are based on SingleStep version 7.6.2 and 7.7.x and may differ from your installed version of SingleStep, or with future versions of SingleStep. The MathWorks provides the configuration information below only as a convenience. To resolve questions or difficulties with SingleStep, refer to the SingleStep documentation, or contact Wind River Systems.

Make sure you have done the following before you begin:

• Configure a shortcut to SingleStep that starts up SingleStep with the correct options (see Setting Up SingleStep).
• Connect the BDM port of your development board to parallel port LPT1 of your host PC.
• Make sure that the jumpers on the phyCORE-MPC555 board are set as described in Jumper Settings.
• Cycle the power (or perform a hard reset) on your development board to set the board to a known state.
