In summary, the following steps are used to program the Flash and verify the assembly process:
(1)
Reconfigure jumpers on 1-2, 3-4, and 5-6 of jumper block J20.The factory default is 5-6, 9-10, and
15-16.
(2)
Power up the system.
This will automatically start the Flash programming step procedure described in section 8.
Since the Flash is initially empty, the module retrieves its IPL code from the BOOTP server.
The IPL code runs and retrieves various other portions of software from the TFTP server.
(a)
Get the file “u-boot-uartboot.bin.scr” from the server and write to Flash.
(b)
Get the file “u-boot-env.scr'” from the server and write to Flash.
(c)
Get the file “u-boot.bin.img” from the server and write to Flash.
(d)
Get the file “uImage” from the server and write to Flash.
(e)
Get the file “ubifs-image” from the server and write to Flash.
(3)
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.
(4)
Turn power off.
(5)
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.
(6)
The manufacturing functional verification tests will execute in an endless loop.
(7)
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.
