We have released a new version (System 4.0) of the system software.
Release history

Changes

  • Fixed follonwing issues of Cloning in the system menu.
    • Fixed an issue where data files with pathname lengths of 50 characters or more could not be cloned.
    • Fixed an issue where the folder on the target device side may not be deleted when cloning the data files.
  • When installing an application with the Appload utility, if you installed an application with the same version name as the currently installed application, the installed application might not start. This has been fixed.

Update procedure

You can update the system software of your device by following the steps below.
  1. Download the new version of the zip file to your PC from the following link.
    E004000.zip
  2. Unzip the zip file on your PC and you will get the following files:
    E004000.PAC
    lib.h
    logapi.h
    libSTARTUPOPH5000.a
  3. Start USB file transfer on the device and copy E004000.PAC to the FlashDisk of the device.
  4. Start Installation files on the device, select the copied PAC file, and install it.
  5. To make your application program compatible with the new version of the system software, copy the following files into your application's project and build the application.
    lib.h
    logapi.h
    libSTARTUPOPH5000.a

    Note:

    • For existing applications that do not use the functions added in the new version of the system software, you do not need to copy these files into your project and rebuild it.
    • When you install and run an application that uses a function added in the new version of the system software on a device of an older version of the system, the OS displays an error message similar to the following when the application calls the function. If you press the BS key at that time, the device will reboot.
