AVR32 Network Gateway Kit for Embedded Linux Development - Atmel

Atmel’s ATNGW100 Network Gateway (NGW) is a development kit for AVR32 microcontrollers. The Network Gateway kit is targeted for AVR based  embedded Linux network application development. The development kit includes a board with AT32AP7000 processor with preprogrammed Linux 2.6.18 operating system, dual Ethernet interfaces, high-speed USB 2.0, SD card slot, RS232 port and I/O extension header. This kit also provides protocol stacks, peripheral drivers (royalty-free) and communications interfaces software. Complete Linux development and debug tools are also provided along with this development kit.

Using this kit, developers will be able to explore the features of AVR32 (in this case AT32AP7000) and also to evaluate the embedded Linux kernel handles serial link/communication and network protocol. The Network Gateway development kit includes some application samples, such as: routing and filtering of traffic between  TCP/IP network to other TCP/IP network and to other interfaces, such as SD cards and USB.

Developer will be able to evaluate application software including USB-to-TCP/IP bridge, USB-to-SD card storage driver and TCP/IP-to-SD card file system driver (FTP, SAMBA). The TCP/IP protocols supports HTTP, FTP, DNS, DHCP, SNMP, SSH, Telnet and SAMBA.

The AVR32 AT32AP7000 processor features:

• Vectored multiplier co-processor
• 32 KB on-chip SRAM
• 16 KB instruction cache
• 16 KB data caches
• DMA controller
• Two 10/100 Ethernet MACs
• 480 Mbps USB 2.0 with on chip transceivers (PHY)
• 16-bit stereo audio DAC
• 2048×2048 pixel TFT/STN LCD controllers
• Serial interfaces: USART, RS232, I2S, TWI/I2C, AC97, SPI, PS/2 and SSC (synchronous serial modules). 

Price of  ATNGW100 Network Gateway is US$69

Latest issues of AVR 32 Network Gateway from AVRfreaks:

• SPI,dataflash does not work at 33 MHz
  Trying to interface the dataflash on the NGW with the SPI at 33 MHz does not succeed in writing the data. The blocks seems to not be written. Erasing is ok.
• USB mass storage does not work with Linux/SAMBA
  Can not use the NGW100 as a USB mass storage device and at the same time have the sd-card mounted in Linux (i.e. made available for Samba).
