      hello,
      I just received my new Core2 and, after following the excellent UIFlow Quick Start I was able to successfully install the Win10 driver, and run the M5Burner.
      however, while burning the UIFlow_Core2 v1.7.1-core2 (or any other previous version actually) successfully completes, after the device resets I only see an on but empty screen - no UIFlow logo or the expected mainpage is displayed.

      this is especially puzzling to me as I can successfully burn and run other apps, such as the downloadable Core2FactoryTest or draw_by_touch for example, without any issue.
      am I missing something here ?
      thanks a grand for your help.
