Single-board computer AS-9260
Begin: 08 (August) 2012
Participants: Oleg Astrahancev
Description: Board AS-9260 is controller based on chip AT91RM9260, core ARM9(ARMv7), with peripheral devices set. The board targeted for development (maketing) projects based on microcontrollers with core ARM926EJ-S production by corporation Atmel, also that can be used for master controller of the target system.


To the board placed sockets USB2.0 (1 Host, 1 Device, Full-speed, 12Mb/s), DBGU, RS-232, RS-485, two 12-pins sockets for placing Ethernet 10/100 Mbps interface module, besides that have place for set two 80-pins sockets type PLD-80 for connect external modules with additional interfaces.

The boards AS-9260 peripheral with processor AT91sam9260 is minimal:

  • sockets for interface USB type A and B;
  • socket DRB-9 for interface DBGU (RS-232);
  • socket PLS-3 for addition interface RS-232;
  • socket PLD-20 for connect JTAG-emulator (ATSAM-ICE, AS-JTAG);
  • chip ROM series DataFlash AT45DB642D-TU (case TSOP28);
  • 2 chips SDRAM total capacity 32 or 64 MB;
  • socket for external module Ethernet PHY connection.

Loader and kernel you can be found here To U-boot let's set loading RootFS from USB-flash:

setenv bootargs root=/dev/sda1 rootdelay=9 rootfstype=ext2

The flash will format to FS EXT2 and to it will write RootFS Debian Lenny. Run the system and configure the internet connection nano /etc/network/interfaces:

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
address 192.168.ХХХ.ХХХ
netmask 255.255.255.ХХХ
gateway 192.168.ХХХ.ХХХ

Into /etc/inittab let's set autologin:

T0:23:respawn:/sbin/mingetty console vt100 --autologin root 

Set repository for updating, into /etc/apt/sources.list

deb lenny main contrib 

After upgrade let's download OpenSCADA sources and resolve dependencies. Natively compile SCADA fails by lack of memory. Some from the situation resolving solutions are next:

  • Build image of RootFS:
    #On other PC
    sudo dd if=/dev/sdc**X** of=/home/your dir/rootfs.img bs=8M conv=sync,noerror
  • Start QEMU with RootFS image:
    sudo qemu-system-arm -M versatilepb -kernel vmlinuz-2.6.26-2-versatile -initrd.img-2.6.gz -hda rootfs.img -append "root=/dev/sda"
  • Compile with next configuration:
    ./configure --disable-FireBird --disable-SoundCard --disable-DiamondBoards --disable-ICP_DAS --disable-PostgreSQL --disable-MySQL --disable-OPC_UA --disable-Siemens
  • Write image with SCADA back to flash.
  • Load and use.

The described method is far not the best then working to improve it. Similarly SCADA is installed to board AS-9200 with processor AT91RM9200.
