  • 4: No upgrade file found

  • 5: Failed to load kernel module

  • 6: Board is not capable of running the current firmware version

  • 7: A piece of on-board hardware is not working correctly

  • 8: Problem related to the storage device (either the USB drive or MicroSD card)

  • 9: Problem related to the registry/NAND

  • 10: The autorun script encountered a load/run error

  • 11: WiFi-related error

  • 12: Unable to find bootable image

A solid error light is displayed during the micro-controller update in BOS 9.0.36. Updating from an earlier OS version to BOS 9.0.36 or later will trigger this light.

On-Board Switch / SVC Button

The SVC button is connected to the GPP_D6 GPIO on the processor. The RESET button is also sent to the PMIC (support micro), which when the button is asserted for four seconds will initiate a hard reset.

Reset Switch / GPIO Button

The RESET button is connected to the GPP_D5 GPIO on the processor. The RESET button is also sent to the PMIC (support micro), which when the button is asserted for four seconds will initiate a hard reset.

MicroSD Slot

The XC2055 and XC4055 have one MicroSD slot. High density memory cards with a capacity of up to 2TB, and SDR104 and microSC3.0 UHS-I ultra-high speed memory cards, are supported

Wireless Module

The XC2055 and XC4055 both have a dual antenna connection
