This section describes how specific components operate on the HD225 and HD1025.
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 the 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 board is being updated | |
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 | |
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 HD225 and HD1025 have one MicroSD slot. There is
...
a 2TB limit on the storage capacity of
...
microSD cards used with the player.
Wireless Module
The HD225 and HD1025 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.
