How to use boards with etrax mcm

This boards are accessable at GSI under etrax201-etrax248.

How to login

Only via telnet: telnet etrax2xx, where xx=01-48
There is two usefull users:
  1. root with with 4-letters password,
  2. hadaq without password and home directory -> /home/hadaq

What's happen after reboot

  1. The image of linux is unpacking,
  2. linux system is starting,
  3. network configuration. It is static and embedded in the image. This is the reason why so many images were created(see chapter: new version of net booting),
  4. the script /home/hadaq/rc is running.
  5. if you are logged in as hadaq, all in the file /home/hadaq/.profile will be run after login

Boot from net

If you have a new board without the system on it or you want to change the system, you should do the following:
  1. go to hadeb05:/home/hadaq/soft/devboard-R2_01 and change the user to root,
  2. set the board into the 'NetBoot' state,
    • for HadControl: while powering up the board short circuit the upper two pins on SWNB1 (next to the MCM)

  3. to set environment variables needed to flash type:
    $> . ./init_env
  4. to flash type (where xx=01-48):
    $> ./flashit -d eth1 -i ./etrax2xx/fimage
    • successful example output:
      $> ./flashit -d eth1 -i ./de-etrax047/fimage
        Using internal boot loader: INTERNAL_NW - Network boot (default).
        Starting boot...
        We're doing a flash write, this may take up to a few minutes...

        END
        Exiting with code 0
         
  5. set the board into the 'FlashBoot' state,
    • i.e. for trb v1: change SW1 to 7
      • restart of the board is NOT needed
    • for HadControl: just power the board, nothing to do...
  6. if you can login and see the content of directory /home/hadaq, booting proccess finished correctly

new version of net booting

Now we have many images with the same system which differs only:
  1. net configuration(IP, netmask,hostname)
  2. NFS configuration(/home/hadaq is taken from hadeb05 or lxhadesdaq).
If the new system development kit is released(a few weeks), we want to change the system for:
only one image, where all above settings will be delivered by DHCP server.
Then the procedure will be like this:
  1. go to hadeb05:/home/hadaq/soft/devboard-mcm and change the user to root,
  2. set the board into the 'NetBoot' state,
  3. set the PATH variable by: ". init_env"
  4. type: boot -d eth1 -i ./fimage
  5. set the board into the 'FlashBoot' state,
  6. login to etrax001(our new board)
  7. change MAC address
  8. restart the board, now you can login on etrax0xx
