XDx33 Theory of Operation

this section describes how specific components operate on the xd233 and xd1033 on board leds there are four on board leds that indicate the following led indication green power/update ( pwr ) displays when the board is powered up and not in reset mode flashes during the firmware update process green file system activity ( bsy ) flashes any time there is file system activity (on any storage device) blue wifi ( wifi icon ) flashes when the player is connecting to the wireless network displays 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 a bootable image 13 the root file system has failed verification, which is used to detect whether the file system has been tampered with you can recover a player that is showing this error code by performing a firmware update with secure boot 14 boot loader failure red alternate the red status led may give one long initial flash to preface an alternate code, described below 2 erase failed 3 write failed 4 verify failed 5 failed to find ubi partition 6 attempt to write unsigned cfe to unit with secure boot enabled 7 failed to find ubi partition 8 failed to create/attach ubi partition 9 unexpected error 10 upgrade script exited abnormally 11 upgrade took longer than expected 12 update completed but update file could not be deleted 13 firmware update file could not be read (from firmware v5 1 40) on board switch the on board switch is connected to the gpio12, which is pulled low when the service (svc) button is pressed conversely, a pull up on the button normally sets the gpio12 to be pulled high reset switch / gpio button the on board switch is connected to the reset circuit pressing down 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 xd233 and xd1033 have one microsd slot, which supports transfer modes up to uhs 1 ddr50 (50mb/s) there is no inherent limit on the storage capacity of microsd cards used with the player wireless module the xd233 and xd1033 have an internal m 2 slot for installing a compatible wireless module the m 2 wireless module connects via cables to two external, attachable wireless antennas ssd module the xd233 and xd1033 have an internal m keyed m 2 slot for atapi ssd drives see ssd requirements docid\ aedgj5b7oao861a on62 for all ssd specifications
