Demo peripherals under Atanasoff 1.4.2 using the Cirrus Logic EP9312



This document describes how to setup and demonstrate various peripherals in Linux.
The peripherals covered include USB, IDE, Audio, Touch Screen, and Ethernet.

1. redboot.bin, ramdisk.gz, and zImage are in the directory 
   cirrus-arm-linux-1.4.2/edb9312 on your Linux host.
  
   Use the download utility to program redboot.bin to edb9312's flash.
   
2. Copy ramdisk.gz and zImage to /tftpboot.
       
3. Connect the Ethernet port on EDB9312 to a hub or switch.
   Power on EDB9312.  Upon RedBoot prompt, use fconfig to set configuration.
   Power off then power on EDB9312 so the new configuration can take effect.

4. Upon RebBoot prompt, do the following:

   load -r -v -b 0x800000 ramdisk.gz 
   load -r -v -b 0x80000  zImage 
   exec -r 0x800000  -s 0x600000 

   Make sure you can bring up Linux.

5. (Optional) Program ramdisk and zImage to flash.

   Power off then power on EDB9312.
   
   load -r -v -b 0x800000 ramdisk.gz 
   load -r -v -b 0x80000  zImage 

   fis init -f 
   fis create -b 0x800000 -l 0x600000 ramdisk
   fis create -b 0x80000 -l 0x100000 zImage
   fis list

   Power off then power on EDB9312.

   fis load ramdisk
   fis load zImage
   exec -r 0x800000  -s 0x600000 

   Make sure you can bring up Linux.

6. (Optional) Run script from RedBoot to bring up Linux.

   Power off then power on EDB9312.

   Upon RedBoot prompt, do the following:

   RedBoot> fconfig
   Run script at boot: true
   Enter script, terminate with empty line
   >> fis load ramdisk
   >> fis load zImage
   >> exec -r 0x800000 -s 0x600000
   >>
   Boot script timeout (1000ms resolution): 3
   Use BOOTP for network configuration: false
   ........................
   Update RedBoot non-volatile configuration - continue (y/n)? y

   Power off then power on EDB9312.
   Make sure Linux can be loaded automatically.
 

7. Power off EDB9312.
   Connect the peripherals to be demonstrated to EDB9312.

   Ethernet: MUST connect the Ethernet port to a hub or switch.
             Prefer DHCP server in the network.
   USB devices: storage drive(Thumb drive).
   IDE devices: hard disk (master), CD ROM (slave).
   Audio: connect speakers to I2S Line Out L/R (J10).
   PS/2 keyboard: connect to J15.


8. Power on EDB9312 and bring up Linux.


9. Demo for peripherals:

9.1 PS/2 Keyboard:  
    You can use it immediately after Linux has been loaded.


9.2 USB Thumb Storage Device:

    cd /mnt
    mkdir thumb
    mount  -t vfat /dev/sda1 /mnt/thumb
    (or "mount /dev/sda1 /mnt/thumb" if the file system type
     is not FAT or unknown.)
    cd thumb
    ls


9.3 IDE Hard Disk:

    cd /mnt
    mkdir hd
    mount  -t vfat /dev/hda1 /mnt/hd
    (or "mount /dev/hda1 /mnt/hd" if the file system type 
     is not FAT or unknown.)
    cd hd
    ls


9.4 IDE CD ROM:


    cd /mnt
    mkdir cdrom
    mount  -t iso9660 /dev/hdb /mnt/cdrom
    (or "mount /dev/hdb /mnt/cdrom" if the file system type 
     is not iso9660 or unknown.)
    cd cdrom
    ls


9.5 Ethernet:

    Use ifconfig to check IP address. Type:
    ifconfig

    (If no DHCP server in your network, you can manually assign one by
    ifconfig eth0 xxx.xxx.xxx.xxx
    However, telnet server and HTTP server may not start.)
 
    Telnet server and HTTP server are running on EDB9312.

    From Web Brower on your computer, you can connect to the HTTP server by

    http://xxx.xxx.xxx.xxx(IP Address of EDB9312)

    You can connect to the telnet server by

    telnet xxx.xxx.xxx.xxx(IP Address of EDB9312)


9.6 Touch Screen

    Use the USB keyboard (not serial port or telnet connection), type
    
    set

    to make sure QWS_MOUSE_PROTO is set to TPanel:/dev/misc/ep93xx_ts

    cd /usr/qt/examples/launcher
    ./launcher -qws

    Use a pen for touch screen) to click Canvas, Scribble,
    Magnifier, or drawline at the upper right corner, and play it.

    Click "Quit" at the lower right corner or press ALT+CTRL+BackSpace 
    to go back to command line.  Upon the command line, type

    clear

    to clear the messy screen.




9.7 Audio Output:

    - Play the music funky.mp3 by:

        playmp3 /funky.mp3 /dev/audio

    - The audio volume can be adjusted by
  
        cmix vol xx
 
      where xx could be a number between 0 to 100.
