2.2 Board descriptions

The SJA1105SMBEVM (SJA1105S Mother Board Evaluation Module, see Fig 1) is designed for evaluating the capabilities of the SJA1105P/Q/R/S Automotive Ethernet switch family and the TJA1102 Automotive Ethernet PHYs, by developing and running customer software. Therefore, the board features the MPC5748G MCU with a rich set of peripherals for communication and automotive applications.

It is designed to allow early adaptions of applications, like a X-to-Ethernet gateway, communication hub, etc.

4.1 Preparing graphical user interface operating environment

If you want to download and run SW on the SJA1105SMBEVM you also need a JTAG-Debug adapter. The easiest solution is the PEMicro “USB Multilink Universal” USB-to-JTAG debug probe (http://www.pemicro.com/products/product_viewDetails.cfm?product_id=15320168), as this is already integrated into the S32 Design Studio IDE.

The following steps are required to bring the SJA1105SMBEVM into operation:

1. Installation of the software development environment S32DS for Power Architecture
2. Import the example project for SJA1105SMBEVM and build an executable file
3. Flash the executable and start it
4. Connect ethernet stations and send traffic
5. Modify the Software according to the special needs of the project

4.2 Install S32DS
