Update the MC75Ax Using Update Loader

7:21 PM 0



An update package file is a ZIP file which can be unzipped to Update Loader files.
Update Loader Files:
Pkgs.lst – This is a list of the files to update.  They can be .cab files, .sig files or .bin files.  This file can be edited in Notepad or any other text editor.
Update Files – the .cab, .bin or .sig files that will be written to the terminal.  The IPL partition & OBM partition CANNOT be updated using Update Loader.  If you want to update a terminal OS that was built with the Symbol Certificate, you can only use files that were also built with the Symbol Certificates.   Also, you CANNOT load an older version of Update Files on the terminal.
StartUpdLdr.exe – This is the application that will find the pkgs.lst file and start the update process. 
Please follow these steps.
1)    Place the Update Files, the pkgs.lst file and the StartUpdLdr.exe in the root of the SD card or the \Temp directory of the terminal. 
2)    Place the MC75Ax device into a Single-slot cradle or 4-slot cradle with Power supplied.  The update will not start without AC power provided.
3)    Click on StartUplLdr.exe to start the Image update process.
Alternative procedures for updating form an SD card:
1)    Place the Update Files and the pkgs.lst file in the root of the SD card
2)    Place the MC75Ax into a Single-slot cradle or 4-slot cradle with Power supplied.  The update will not start without AC power provided.
3)    Press 1-9-PowerButton from keypad.  This will cause MC75Ax to ColdBoot.  Within 1 second of ColdBoot, press any one of the Trigger keys (yellow button) on the MC75A0 to activate the updateloader.

When the process is complete, the terminal will boot to the calibration screen, this may take approximately 5 minutes. The calibration itself may go very slowly for 30 seconds or so.
