The Ugoos AM3 is a small set-top box based on the Amlogic S912 SoC,
|
||||
with a board design that is very close to the Q20x development boards.
|
||||
The MMC max-frequency properties are copied from the downstream device
|
||||
tree.
|
||||

||||
https://ugoos.com/ugoos-am3-16g
|
||||
|
||||
The following functionality has been tested and is known to work:
|
||||
- debug serial port
|
||||
- "update" button inside the case
|
||||
- USB host mode, on all three ports
|
||||
- HDMI video/audio output
|
||||
- eMMC, MicroSD, and SDIO WLAN
|
||||
- S/PDIF audio output
|
||||
- Ethernet
|
||||
- Infrared remote control input
|
||||
|
||||
The following functionality doesn't seem to work:
|
||||
- USB role switching and device mode on the "OTG" port
|
||||
- case LED
