    STM32 strange flashing process

    Tim Baures

      Hi!

      When I flash a .hex or .bin file with a ST-LINK V2 device on my STM32F4 microcontroller (with ST-LINK utility), the program only works if both the ST-LINK V2 and my MCU board stay connected to the computer (through a USB cable). Whenever I unplug one of them the program just flashed on the board does not run anymore.

      Does anyone have any idea of what is happening ?

      Thanks for your help!
