XD5 Theory of Operations

This section describes how specific components operate on the XD235 and XD1035.

On-Board LEDs

The four on-board LEDs have the following indicators:

LED

Indication

LED

Indication

Green power (Pwr)

Displays when the board is powered up and not in reset mode. Flashes during firmware update process.

Green file-system activity (Bsy)

Flashes any time there is file-system activity (on any storage device)

Blue (WiFi)

Flashes when the player is connecting to the wireless network. Displays solid when connected.

Red status (Err)

Flashes a certain number of times to indicate which error is occurring. The flash codes are described below:

  • 2: Unspecified error

  • 3: Network recovery script is preparing to run on a device configured for network recovery

  • 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

On-Board Switch / SVC Button

The Service (SVC) button provides a dedicated GPIO button (GPIO12) for the OS. Pressing the SVC button pulls the pin low. Conversely, releasing the button pulls the pin high.

Reset Switch / GPIO Button

The Reset button is connected to the reset circuit. Pressing the Reset button will send an initial signal to the system software and holding the reset button low for approximately 4 seconds will cause a hard reset.

MicroSD Slot

The XD235 and XD1035 each have one MicroSD slot, which supports transfer modes up to UHS-1 DDR50 (50MB/s). There is a 2TB limit on the storage capacity of microSD cards used with the player.

Wireless Module

The XD235 and XD1035 have a dual antenna connection which allows users to install a BrightSign wireless module. BrightSign modules are configured to work with 802.11.N or 802.11.AC access points.

This connection has a Bluetooth option.
