Overview

The U-Media HCA-100 is a small "kitchen radio" like device that - apart from FM radio - supports playback of digital Audio. Audio sources can be a locally-attached USB storage device, Internet Streaming Radio, as well as [[UPnP AV] sources available via WLAN.

Notes

Next to the USB A socket, there is an unpopulated RJ-45 jack and footprint for matching magnetics. Since the SoC is mainly intended to be used for Ethernet switches/routers, it's quite surprising that this jack is not populated.

[edit]

Serial Console

There is a populated four-pin header on top of the device. If you place the main pcb in a way that the "alarm" button faces downwards (FM antenna left, WLAN antenna right), then the pinout is as follows (from left to right):

  • 1: RxD (into SoC)
  • 2: TxD (from SoC)
  • 3: GND
  • 4: +5V

[edit]

Firmware

The firmware is based on linux 2.4.26-uc0. It contains busybox and some device-specific binary programs (containing DMA in their name) which actually implement the radio functionality.

[edit]

Object Code

There are no known legal sources for binary firmware images anymore. Allnet seems to have removed the object code from their server, though allegedly it was there at some point in the past.

[edit]

Firmware Image

The vmlinux kernel image can be extracted from the firmware image via 

dd if=ALLSOUND-EN-1.2.2.1.img bs=16 skip=1 | zcat > vmlinux
[edit]

Source Code

20070108: There is a sourcecode tar file available at http://www.allnet.de/downloads.php?produkt=ALLSOUND. However there seems to be no instruction how to build an image and no source for the graphic interface.
