4. Once all sections of the Flash are written successfully, a success message is displayed.
If the test succeeds, then proceed to the next step, otherwise troubleshoot.
5. Turn power off.
6. Next run the functional tests as described in section 7 below.
Insert the manufacturing jumper or use a pair of tweezers to place the board into manufacturing test
mode and turn power on again to start the functional tests.
When the jumper or tweezers is detected correctly, the message “
Factory jumper detected.
" is
displayed. At this point you can remove the tweezers.
7. The manufacturing functional verification tests will execute in an endless loop.
8. If the test is successful, then remove the manufacturing jumper (if one was used) and the module is
good for shipping.
Otherwise, troubleshoot the module or the process.
5 Test and Programming Setup
5.1 Materials needed
The following materials are required to perform the programming and functional verification steps.
•
A Linux PC properly configured with BOOTP and TFTP servers and the programming files
•
A serial console terminal, such as a PC running a terminal emulator.
•
Two media players to be used as source of video content.
•
A TV monitor with HDMI input, capable of displaying 1080p60 video.
•
One USB flash drive with standard format.
•
One 12V power AC-DC converter rated for 2A.
•
One Ethernet RJ-45 cable.
•
Three good quality HDMI cables.
•
One 2.5mm stereo plug to DB-9 for the serial console port.
5.1.1 The HDMI cables
Please obtain HDMI cables of good quality. For this test setup the cables need to be capable of
operating at 1080p60, so the extra-thin cables will NOT work. Ensure that the cable is capable of
1080p60 by testing it from the media player to the TV monitor, with the media player configured for
1080p60 output.
