3. Febr. Februar in Debug/Flashen/Bootmanager-Probleme? Nokia Dbox2 für Kabel gekauft 1x geflasht – rennt 14 Tage wunderbar – Netzteil defekt, bekomme eine andere Box im .. p.s. gibts für das Löten ne Anleitung?. ich habe versucht meine dbox2 zu updaten mit hilfe der anleitung debug: DDF: Calibrating delay loop debug: DDF: BogoMIPS debug: BMon V mID. Bengt Mårtensson > Private Site > dbox2 It is possible for the dBox (in debug mode!) to boot entirely from a server, not using any (nonvolatile).

The goal of this guide is to proved help on setting up a Unix or Linux server for providing the dBox with some useful services. It is aimed at the beginner to intermediate user.
Nothing really new is presented here. The emphasis is on traditional Unix services, getting them to work, to troubleshoot them. It is only when you network the dBox, that you can take advantage of its full power. A number of services exist, and new are invented regularly.
Some of these are multimedia related, and enables the box to digitally record DVB-transmissions, or to reproduce video or audio material. This is not the topic for the present guide, that instead focuses on the more traditional Unix services. It is possible for the dBox in debug mode!
The necessary parameters for booting will be received from a server, another possibly different server provides it with the necessary boot loader u-boot, in the past “ppcboot” and secondly with a Linux kernel. The root file system is NFS-mounted from a server. This mode of operation has many advantages:. In many situations, computers have to be referred to in a unique fashion.
This can be done with IP-Numbers, or, if the involved computers can understand it, symbolic names. To translate the symbolic names to IP-numbers “hostname resolving”anlwitung number of mechanisms have been proposed.
For a small home network, this may look like:. This file is then distributed to all computers in the network. Now the symbolic names can be used in configuration files. The dhcpd-daemon supplied with most Linux distribution is a very versatile program. This file will typically look like:.
The MAC-address of the dBox needs to be entered here. Often, it is printed on the back plate of the dBox. Otherwise, a command like arp -a can often be used to determine it.
The MAC-number vbox2 a dBox always starts with ” For more information, see the man-pages for dhcpd and dhcpd.

Unfortunately, unless you remove the Ethernet cable from the dBox when booting, unlike the NFS-server and the TFTP-server, the dhcpd-daemon interferes with normal operation of the dBox — it will simply force the box to boot ableitung the server.
I do not know of a really elegant solution: As can be inferred from the configuration file, there is a fair number of things that can go wrong. Also, as is discussed in this threadsome versions of dhcpd do not work with the Tuxbox.
For reference, we show a successful boot “godzilla” is the server, “dbox” the dBox, having MAC-address TFTP is a very simplified file transfer protocol. For the Tuxbox, it serves the client with the boot loader u-boot and the Linux kernel kernel-cdkas well as optionally the logo files logo-fb and logo-lcd. This is where u-boot and kernel-cdk reside. It should normally be the same as the –with-bootdir parameter to configure.
There is not too much that can go wrong, basically only “File not found”. Since the TFTP-daemon dbx2 to its base directory, all file names are interpreted with respect to this directory, which can sometimes be confusing. For a file server for the dBox, there appears to be a consensus that it offers better performance and reliability than other alternatives.
The NFS server is in general quite robust, and seldomly makes problems. Most problems are permissions problems.
However, the Tuxbox does not implement file locking anleitjng NFS, so file systems have to be mounted using the “nolock” option on the client, that isotherwise the mount may hang. There is a vast number of different services that may or may not be of interest. Multimedia related services are, e. There are also the traditional Unix-Services.
These can, possibly after installing some client software component, in general be used with the Tuxbox. To have your own nameserver in your LAN may be useful, or at least nice.
The dhcpd daemon, setup like here proposed, takes over the task of these services, which are therefore not needed. In this article a non-interactive flashing using the “dboxflasher”, a specially compiled u-boot, is described. For trouble shooting, a log from the serial console also called bootlog dboxx2 indespensible.
See wiki for some more details. Without it, no sensible debugging is possible, just guessings.
Yet another guide o The dBox IR Keyboard. Yet another guide on setting up a Linux server? The three services we will cover are: It is sometimes sensible to anleifung up only, e. This mode of operation has many advantages: The flash memory, i.
Using the flash functions of, e. Neutrino, the flash can be read out, or the flash can be new debjg. Disk space, also in the root partition, is “unlimited”. Very practical for development: After a successful build, the changed software immediately resides on the dBox, without need for flashing. Host name resolving In many situations, computers have to be referred to in a unique fashion.
For a small home network, this may look like: This file will typically look like: This is a template for dhcp. You may have to modify this file manually. Please see the documentation for your server and for dhcpd. Troubleshooting As can be inferred from the configuration file, there is a fair number of things that can go wrong. Troubleshooting There is not too much that can go wrong, basically only “File not found”. Typically, the file may look like: Troubleshooting The NFS server is in general quite robust, and seldomly makes problems.
