2.2 Running the self-test program
The MPS2+ FPGA platform uses a self-test program to test its main components. This self-test program
is specific to the prebuilt image, which is based on the Cortex-M3 DesignStart Eval example system.
If you extend the example system, then you may need to modify the self-test program.
If you need to modify and recompile the self-test image, you are required to install legacy support in
Keil
®
MDK. This provides the low-level interface which is used by the self-test. Source code for the self-
test is located at m3designstart/selftest/Build_Keil/ in the deliverables.
To run a self-test program, follow these steps:
1. Connect an RS232 serial lead to the General UART connector (FPGA), on the MPS2+ platform.
2. Configure the UART according to the following settings:
Table 2-1 UART configuration
Configuration Value
Baud rate 38 400
Data bits 8
Stop bits 1
Parity None
Flow control XON/XOFF protocol
3. Select the self-test program that you want to run based on the following options available that are
displayed by the UART console window when the MPS2+ platform has booted up:

Note
To run Test 1, AACI (Audio), you must connect a 3.5mm stereo jack lead from the audio output
connector to the audio input connector.
When the test runs, the console window displays the self-test status:
