The Updater is an add-on and not part of the emLoad software. It has been designed to give the end user the possibility of an easy firmware update without using the HEXLoad program. It is shipped as source code, which is required to modify and to recompile the tool.

How the Updater works

After the Updater is started it shows the dialog shown above which gives the user the possibility to set up the COM port of the PC. After the Updater tool gets contact with the target it shows a notification message in the application window. Now the user should only press the ‚Start™ button or the key to update the target. The tool now clears the flash, programs the new file into the flash, makes a CRC check and makes the target application valid.

Using the Updater

The following steps show how to use the Updater: Connect the target UART with the desired COM port of the PC. Start the Updater and select the desired COM port.
Connect the target to the power supply.
Press the "Start" button or the (ENTER) key.
Now further targets can be updated.
