This section describes how specific components operate on the HD223 HD224 and HD10233HD1024.
On-Board LEDs
There are four on-board LEDs that indicate the following:
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 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. | |
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 HD223 HD224 and HD1023 HD1024 have one microSD slot, which supports transfer modes up to UHS-1 DDR50 (50MB50Mbit/s). There is no inherent limit on the storage capacity of microSD cards used with the player.
Wireless Module
The HD223 HD224 and HD1023 HD1024 have an internal M.2 slot for installing a compatible wireless module. The M.2 wireless module connects via cable to a single an external, attachable wireless antenna.
