This section describes how specific components operate on the XC2055 and XC4055
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) | Illuminates when WiFi is connected and flashes when searching for a connection |
| Red status (Err) | Flashes a certain number of times to indicate which error is occurring. The flash codes are described below:

On-Board Switch / SVC Button
The on-board switch is connected to the GPIO02, which is pulled low when the service (SVC) button is pressed. Conversely, a pull-up on the button normally sets the GPIO02 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 XC2055 and XC4055 have one MicroSD slot, which supports transfer modes up to UHS-1 DDR50 (50MBytes/second). There is no inherent limit on the storage capacity of MicroSD cards used with the player.
Wireless Module
The XC2055 and XC4055 both have a dual antenna connection. This allows users to install a compatible wireless module without disassembling the unit. This connection has a Bluetooth option.
