X4x0 Autoboot Configuration

Updated Jul 2, 2026

By default, the Ettus USRP X4x0 Series requires a manual press of the power button to boot up after power is applied. However, this behavior can be changed by enabling the "autoboot" setting in the device's internal EEPROM causing the device to automatically boot on after power failures. This is managed via the System Controller Unit (SCU).

  1. Connect to the SCU Console: Connect the USB-C Console port on the front of the USRP X410 to your host computer.
  2. Open a Serial Terminal: Open a serial terminal emulator (such as PuTTY on Windows or `screen`/`minicom` on Linux) and select the serial port corresponding to the MCU/SCU. Set the baud rate to 115200. (Note: The SCU usually enumerates as the second or third USB serial port).
  3. Enable Autoboot: Once connected, press Enter to bring up the `>` prompt. Type the following command and press Enter: `eeprom-set-autoboot on`

The USRP X4x0 device will now boot up after power is applied.
