Hello, we have created a MicroZed carrier card that provides the 5V power source through the expansion connectors. However, we like to plug in the USB cable sometimes to see the serial printout. Some questions:
1) Is there any issue in having both supplies connected at once? So USB cable connected as well as the 5V regulator on our carrier card?
2) Is there any way to disable getting powered via USB? I'd like to test some power cycle reboot stuff while watching the USB UART data, but I need a true power cycle (including the carrier card components which is not powered by USB). Any recommendations?
