Inserting the Battery
Once you have confirmed the firmware is successfully programmed, you can insert a battery on the board. This battery
can be used to retain power to the RTC even when the MOD is not powered.
To do this, simply insert a CR1225 or CR1220 battery into the RTC battery slot on the right edge of the MOD. Make
sure the “+” is on the top.
Note
: You will likely need to remove the MOD from the APP board when you do this. When you put the MOD back
onto the APP board, make sure that all 5 connectors are firmly snapped in place. It is a common error to not snap the
5
th
connector into place. When this happens, it will seem like the MOD is operating correctly in that it might boot up,
but then unexpected behavior can happen later. It is therefore a good idea to make doubly sure that the MOD and APP
boards are firmly connected at this stage (you should hear a slight “snap” when that fifth connector is firmly in).

Programming Other Modules
Once you have programmed one module, you can program other modules by doing the following steps:
(1) Connect the module to be programmed on the DM8168-APP-02.
(2) Power on the DM8168-APP-02
(3) Connect the MSP430 emulator to the DM8168-APP-02
(4) Click on the “AUTO PROG” button on the Elprotronic screen.
(5) [The steps to check programming was successful using u-boot or the linux software are the same as before]
(6) Once complete, power the system off, remove the power plug, and disconnect the emulator from J10.
