This section describes how specific components operate on the HD224 and HD1024.
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. | |
Service 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 Button
The Reset button 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 HD224 and HD1024 have one microSD slot, which supports transfer modes up to UHS-1 DDR50 (50Mbit/s). There is no inherent limit on the storage capacity of microSD cards used with the player.
Wireless Module
The HD224 and HD1024 have an internal M.2 slot for installing a compatible wireless module. The M.2 wireless module connects via cable to an external, attachable wireless antenna.
