The device is based on Texas Instrument AR7, so you need the target.ar7 in OpenWrt trunk.
Untested, probably unsupportable due to limited RAM.
|AR7 TNETD7300AGDW||16MB||2MiB||4 x 1||No||Yes||Yes|
The device has the following connectors on the rear (left to right).
- Auxiliary antenna.
- ADSL input connector.
- Power connector (12V 1.2A).
- Reset button.
- Large On/Off button.
- 4 numbered RJ45 10/100 MBit connectors.
- Main antenna.
The flash chip is an Intel TE28F160C3-B 16Mbit (2MiB) 3.0V Flash memory.
A serial console can be connected to J4.
The serial signals are at a 3.3V level, so you need to use a level convertor, see port.serial
The serial signal itself is 115200 baud, 8 databits, 1 stopbit, no parity (8N1).
The pinout for the serial is
Disposition on the board:
To enable JTAG functionality, you must short-circuit SHORT pins or put 100R resistor. (At your own risk)
The AR7 chip has a small memory banks on the chip : 4Kb PROM (@0xBFC00000) and 4Kb RAM (@0x80000000)
The FLASH is located at 0x90000000 (CS0) and RAM is located at 0x94000000 (CS1)
