Enigma 2 is a framework for Linux receivers & is the default interface for several Dreambox receivers, like the DM800.

Release notes

Team DuckTales proudly presents the first enigma2 alpha image for Kathrein UFS-910.
This image should be seen as a proof of concept - there are many bugs and some hardware
which is not supported at the moment. If you are a developer, and you have experience in
(embedded)hardware/linux-dvb-api coding feel free to contact us - you're welcome!

To test this enigma2 image you need a running nfs server and a serial & network
connection to the receiver.

1. extract the tgz file on the server and set the directory in /etc/exports
   for example:
   /nfs/target_enigma2 192.168.0.0/24(rw,no_root_squash,sync,no_subtree_check)

2. restart nfs server

3. connect via serial console to the receiver

4. turn on the receiver and hit enter in serial console
   you should see the following prompt:
 
   Hit any key to stop autoboot:  0
   STB7100-REF>

5. customize the follwoing settings to your network environment and type them into the
   serial console (without the doublequotes):
  
   "set ipaddr '192.168.0.25'"
   "set serverip '192.168.0.1'"
   "set gateway '192.168.0.1'"
  
7. to set the bootargs also type:
 
   "set bootargs 'console=ttyAS0,115200 root=/dev/nfs nfsroot=/nfs/target_enigma2 rw ip={$ipaddr}:{$serverip}:{$gateway}:255.255.255.0:kathrein:eth0:off mem=64m coprocessor_mem=4m@0x10000000,4m@0x10400000 nwhwconf=device:eth0,hwaddr:${ethaddr}'"
   "setenv bootcmd 'nfs a5000000 {$serverip}:/nfs/target_enigma2/boot/uImage;bootm a5000000'"

   where /nfs/target_enigma2 is the directory you added to /etc/exports
 
8. to save the settings type "saveenv"

9. simply type "boot" or restart the receiver with the power-switch. now enigma2 should boot.
