Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

Hello, when I launch the demos on the gh-pages branch, it works. But when I launch the demos on the current master branch, I get this error :

Yes, sorry about that. You need a newer kernel binary. Since Linux 4.0 or 4.1 they changed the endianess behavior of virtio. I didn't update the kernel, because the smp version doesn't work yet and everytime I update the kernel the repository increase by a few MB.

you can try http://jor1k.com/jor1k/bin/or1k/vmlinux.bin.bz2

Also I plan to change a lot of drivers to use virtio. That's why I might wait until Linux 4.2 until I update everything.

@s-macke : thanks ! I tried without success, same error. By the way, could you send me the source code for http://jor1k.com/sync/upload.php and the "how to setup the websocket server" wss://relay.widgetry.org/ ? I'd like to have a working installation on one server. How is going the local file system integration ? Also waiting for linux 4.2 ? Great job, I love your projet !

@remisharrock The websocket server is easy to setup, just run the Python script: https://github.com/benjamincburns/websockproxy

The cloud function was broken. Fixed it. :)

Here is the script. It never worked flawless.

I. e. the user seems to have to upload the whole file and then it is checked if the size matches. This check should be done before uploading somehow and then the file should be rejected. Also I am not sure, if the error messages are returned correctly.

There is also some shell command executed dependent on a user provided string. This is not a good style. Even if the string is cleared of special signs.

It might be also good to send an already compressed version of the file for improved upload speed.

<?php
header('Access-Control-Allow-Origin: *');
ini_set('upload_max_filesize', '1M');
ini_set('post_max_size', '1M');

function clean($string) {
   $string = str_replace(' ', '-', $string); // Replaces all spaces with hyphens.
   return preg_replace('/[^A-Za-z0-9\-\.]/', '', $string); // Removes special chars.
}

$target = "tarballs/";
$target = $target . clean( basename( $_FILES['uploaded']['name']) ) ;
$ok=1;

//This is our size condition

if ($uploaded_size > 1048576)
{
        echo "Your file is too large.<br>";
        $ok=0;
}

//This is our limit file type condition
if ($uploaded_type =="text/php")
{
        echo "No PHP files<br>";
        $ok=0;
}

//Here we check that $ok was not set to 0 by an error
if ($ok==0)
{
         Echo "Sorry your file was not uploaded";
}
//If everything is ok we try to upload it
else
{
        if(move_uploaded_file($_FILES['uploaded']['tmp_name'], $target))
        {
                echo "The file ". basename( $_FILES['uploadedfile']['name']). " has been uploaded";
                shell_exec('bzip2 -f '.$target);
        }
        else
        {
                echo "Sorry, there was a problem uploading your file.";
        }
}
?>

I have started to move all binary into a submodule. Once finished I won't have to worry anymore about the size of repository. d49616932af50f9f9cc6a1366ded18c25b3c5840

Done, the last commits change all binary folders to the submodule. The master branch is finally usable again. Can you test it?
