XD5 Theory of Operation

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 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
