The following procedure shall be used to set-up the text fixture, load the necessary kernel and test software to validate the results. The intent of these test steps are to ensure the quality of EVIC’s production boards.
Sections
Kernel Loading
The EVIC will need the production kernel binary files installed on the device. The following steps will provide you with the instructions on how to perform this process.
Install the ADIM-Flasher tool onto your workstation. You can choose between x86 or x64 installers.
Go through the setup wizard to successfully install it.
Install boot jumper into the 20-pin wiring harness.
4. Plug USB cable from EVIC to Workstation (Host computer)
5. Launch the ADIM-Flasher tool and power on the EVIC display with +12V. The board should go into boot mode and initialize. You should see a similar screenshot as shown below.
6. Go to the “Settings” page in ADIM-Flasher and select the following binary files: XLDR_NAND.bin → EBOOT.bin → NK.bin → boot_screen.png (any image cropped at 800x480). Press the “Save” button.
7. Select the “Flash” button and wait until it is succesfully flashes EVIC. You can monitor the progress bar on the bottom right-corner.
Test Fixture Setup
Analog Inputs
Use x5 22k resistors in series, powered from 5V to generate different voltages for each channel. See schematic below for wiring connector pins P4 and P5.
Digital Inputs and Outputs
Use x7 inverters on pins 1-7 on connector P3. The inverters are used to convert ground to 12V. No inverter is needed for pin 8. See schematic below for wiring connector pins P3 and P5.
CAN Channel
A test EVIC board is needed to transmit CAN messages onto the CAN lines of a production EVIC board. Each CAN line (High and Low) will need to be wired to both the Test and Production EVIC boards.
EVIC Verifier Test Application
Test Verification application will need to be loaded onto production EVIC board prior to testing.
Please select “skin.xml” file from the provided software to selection application.
2. Power “Off” and “On” EVIC board. The test application will automatically start and execute the tests for each analog and digital inputs and outputs. The tests are normally done in 2-4 seconds.
3. If the board Passes, the following message will appear:
4. If the board Fails, the following message will appear:
Note:
If the CAN messages are not set-up, the application will continue to test in absence of CAN.
