Removing the power plug and inserting it again while the power supply is energized may damage the AM574x IDK EVM and/or other devices attached to the board such as emulators that provide an alternate path to ground. Removal of AC power from the external power supply is a safer method, if required. It is also recommended that the external power supply have the common return bonded to earth ground. If this is not possible, a separate connection from the board ground to earth ground may need to be provided. Test fixtures that repeatedly cycle main power on and off should have the board ground bonded to earth ground at all times during this testing.
