I have read the official data manual, the recommended voltage of USB_VBUS is 3.3V, when I designed the IMX8MM development board, I directly connected the USB1_VBUS pin to the 5V of USB_OTG_VBUS, what problems will be caused if I connect it like this?
And when I used mscale_ddr_tool for ddr4 stress test, when I clicked download button, it got stuck in "Waiting for board configuration from PC-end..." Is the USB_VBUS connection 5V causing this problem?If not, then why？
