I'm facing the issue were the USB connection is re-connecting, which results that STM32CubeProgrammer re-flashing the device over and over again when the fip-boot has be fully loaded.
So what can cause this restarting and re-connection? Is it something with U-boot?
I have heard that CubeProgrammer may having some issues with timeouts, but in this case, the board is just restarting itself. FAQ : STM32MP1 STM32CubeProgrammer USB reconnect e... - STMicroelectronics Community

Here is the schematic of the USB. I'm using USB Micro.
This is the configuration of the USB-OTG for U-boot.
&usbotg_hs{
pinctrl-names = "default", "sleep";
pinctrl-0 = <&usb_otg_hs_pins_mx>;
pinctrl-1 = <&usb_otg_hs_sleep_pins_mx>;
status = "okay";
/* USER CODE BEGIN usbotg_hs */
/* This board does not have any USB-C connector */
/* USER CODE END usbotg_hs */
};
Full configuration here: Configuration U-Boot
