(This is a work in progress!)
The Qualcomm Atheros DB120 is the AR9344 (Wasp) reference platform.
The Qualcomm Atheros DB120 reference platform consists of:
- AR9344 SoC - mips74k core, USB, ethernet, 10/100 ethernet switch, 2x2 2/5GHz 802.11n wireless
- 128MiB DDR RAM
- 16MiB NOR flash
- 128MiB NAND flash
- AR9380 3x3 5GHz 802.11n wireless, connected via PCIe
- AR8327 10/100/1000 ethernet switch
It also includes a variety of external ports, including:
- I2S digital audio
- mini-PCIe (which requires a board modification to disable the AR9380 3x3 chip)
- External MAC connection (the mini-PCI connector) to speak to slave devices over the MAC/PHY bridge
The board has a bunch of different modifications that allow it to do a variety of things, including enabling i2s audio, enabling the mini-pcie slot for an external NIC and booting off of NAND flash directly. No, the board modifications aren't public.
The default flash layout is:
- 256KiB (uboot)
- 64KiB (uboot environment)
- 6336KiB (rootfs)
- 1408KiB (kernel image)
- 64KiB (mib0)
- 64KiB (ART)
The ART partition holds the configuration for both wireless devices and the on-board ethernet MACs. Check DB120.hints for the locations of these.
