I/TC: Primary CPU switching to normal world boot - I/TC: Forced system reset PSCI - Restarting from the beginning

DMårt · ‎2024-08-11

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 flashlayout:

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 */
};

Here is the solution. Then it boots into U-boot.

alias {
   serial0 = &uart4;
};
