Hi,

Where can i find information on where I can set kernel parameters for the vu+uno kernel booting?

Are there tools available on how to extract root filesystem, boot filesystem, second stage loader if applicable, specific for vu+uno?

I want to learn more on how the image is glued together specific for vu+uno.

I have a dm8000 where I find the second stage loader very handy to play with parameters via telnet, but apparently the vu+ doesn't have such a menu ? or is it a config via serial line?

Are there ways to boot up the kernel from a usb stick partition and mount root file system also from a partition on the usb stick?

nfidump 9 on your dremabox can nicely extract the ubifs root file from their ZIP files without any nandsim modules, etc and it can also extract their old nfi format.

BA 9 can also nicely extract and boot such images on your Dreambox.

ok thanks for the nfi dump tip. I'll check it out.

Is this tool also available on linux PC?

Any idea where I can modify kernel boot parameters for Vu+?

Use the source code. See the wiki for instructions.

The kernel source code is off course the best place for a user to change kernel command line parameters :-)

You can enter the bootconsole when you have a nullmodemcal, and use STRG+C to interrupt booting, then you can
enter kernel command line.

When booted cat /proc/cmdline will at least tell you which parameters you booted with.

nifdump ins only available on original dreamboxes, I stopped creating Linux and Windows PC versions and both pli and vu+ lack a useable block2mtd driver so you can only unpack with nandsim driver (on the box or on a Linux PC).
