* Ethernut 5 general board support
|
||||||
|
*
|
||||||
|
* Ethernut is an open source hardware and software project for
|
||||||
|
* embedded Ethernet devices. Hardware layouts and CAD files are
|
||||||
|
* freely available under BSD-like license.
|
||||||
|
*
|
||||||
|
* Ethernut 5 is the first member of the Ethernut board family
|
||||||
|
* with U-Boot and Linux support. This implementation is based
|
||||||
|
* on the original work done by Ole Reinhardt, but heavily modified
|
||||||
|
* to support additional features and the latest board revision 5.0F.
|
||||||
|
*
|
||||||
|
* Main board components are by default:
|
||||||
|
*
|
||||||
|
* Atmel AT91SAM9XE512 CPU with 512 kBytes NOR Flash
|
||||||
|
* 2 x 64 MBytes Micron MT48LC32M16A2P SDRAM
|
||||||
|
* 512 MBytes Micron MT29F4G08ABADA NAND Flash
|
||||||
|
* 4 MBytes Atmel AT45DB321D DataFlash
|
||||||
|
* SMSC LAN8710 Ethernet PHY
|
||||||
|
* Atmel ATmega168 MCU used for power management
|
||||||
|
* Linear Technology LTC4411 PoE controller
|
||||||
|
*
|
||||||
|
* U-Boot relevant board interfaces are:
|
||||||
|
*
|
||||||
|
* 100 Mbit Ethernet with IEEE 802.3af PoE
|
||||||
|
* RS-232 serial port
|
||||||
|
* USB host and device
|
||||||
|
* MMC/SD-Card slot
|
||||||
|
* Expansion port with I2C, SPI and more...
|
||||||
|
*
|
||||||
|
* Typically the U-Boot image is loaded from serial DataFlash into
|
||||||
|
* SDRAM by the samboot boot loader, which is located in internal
|
||||||
|
* NOR Flash and provides all essential initializations like CPU
|
||||||
|
* and peripheral clocks and, of course, the SDRAM configuration.
|
||||||
|
*
|
||||||
|
* For testing purposes it is also possibly to directly transfer
|
||||||
|
* the image into SDRAM via JTAG. A tested configuration exists
|
||||||
|
* for the Turtelizer 2 hardware dongle and the OpenOCD software.
|
||||||
|
* In this case the latter will do the basic hardware configuration
|
||||||
|
* via its reset-init script.
|
||||||
