OzXodus released their cromwell sources, so you don't even need to look in the binary

Maybe you should make a "Xenium Gpl Violation Thread" in the ozxodus forum, and not thread crap this one.
And since its obvious looking at your posts that you are "with" franz, maybe you have never heard the expression, "Those who live in glass houses should not throw stones".  At least 1 'group' of code from smartxxOS has been shown to be taken from cromwell already here, how many have you found in xenium's OS?
and dont answer here, go start your own thread.

[...ReLLiK]

BTW, where is Franz after all these allegations he is getting? I can't seem to ever remember a whole lot of good coming out of his name! Sorry if this is a bit of topic, but it just gets to me.

ou, trust me!
HE IS ARROUND!

FRANZ! HUH HUUUU  

He just cant hear you for the moment. He has sand in his ears!

ozxodus has a full xdk unit with kernel debuger  i highly doubt this is a ozxodus issue  more then a smartxx as i recall smart xx making the statement they scraped the old stuff when they spilt and started making their own.

Foir awhile.. alot of people were screaming for them to release their source.. in the end.. only part was released.

However.. someone could/should look into their binaries.. if only to be fair and clear.

Course.. that research wouldn't be posted in this thread.. or this forum.

( -> OzXodus/Xenium forum on XS )

Do we really need the attitude that has already been expressed by one poster above, the "us" and "them" concept.  Come on....are we really going to let this divide our community this way?  Its good that we are able to have checks and balances like this thread to help all of us understand what exactly is going on inside of out XBoxes, but we dont need to turn it into a debate which will set up camps on either side, leading to a breakdown of the communal spirit that I think we all, for the most part, try to keep up around here.  

paul, do yer work, this is a good idea, keep it up.  Like I said checks and balances.  Altho I do think that even if there is a multitide of evidence of GPL violation, no sources will be released, but I could be wrong.  

To everyone else, just lets stop (myself included) the stupid name calling and divisions we are letting into this community.

Hi There all

Now this is only "my opinion for whats its worth" which as free speech dictates we ARE ALL entitled to.

I think the whole reason for this thread being started is to once again highlight how untrustworthy the smartxx team are, this is not my opinion but proven fact.

Look at the Evo-x M8 bios saga, and for example when the initial  hype over smartxx chip with LCD feature it was hyped and hyped, but when hard facts about the features of the LCD feature was asked for by myself and others in their IRC forum, No reply was forth coming now upon pushing the point to clarify the technical details of this feature I was kick/banned from smartxx 's IRC channel.

I for one think that when this sort of behaviour is going on what else can the smartxx team be guilty of

They are after all doing all this to line their own bank account possibly at cost to others.

So the bottom line is that OZPAUL is excersizing HIS right to free speech and this allows YOU & I the people who put cash in the smartxx teams bank accounts the  information about what type of people WE are dealing with. This information empowers us to make decisions about where we spend our cash dollars.

And I for one personally will not use the smartxx units after initally purchasing one for evaluation purposes which were not very long indeed before offloading this
"in my opinion" inferior unit

So to OZPAUL  Sir I salute you as a gentleman, please keep us mere mortals informed of the shady charcters out there, as many of us are not in the position to understand and spot when we are being shafted by the shady bunch.

very well put markduncan, I couldn't have said it better.

thanks oz_paulb for the heads up.

[greengiant]

The work being done is very good, trying to find if GPL code has been used or not in Smartxx OS. And add onto the list of things against Smartxx.
Thats fine, people should know whats going on.
But I find this to be somewhat sided against smartxx, withought even looking at XOS. Others have pointed out this fact.

And as Ozpaulb has pointed out, Franz was on XboxLinux and he did write some of the cromwell stuff. So it is his right to include his work in his project. (Please tell me if this is wrong via GPL)

Shallax put the XOS perfectly. Those 3 questions should be discussed and if possible investigated.

I checked the Xenium section, and there is no thread started. So Iam guessing no one is interested, i guess the scene is just just con smartxx at the moment.

[ShALLaX]

... it was just released to fob us all off, perhaps?

2) That didn't answer the question ;p.  Cromwell has been openly available to evaluate for fitness of purpose for a hell of a long time.  It should have been obvious that it wouldnt have made a great OS to start with.  How comes they didnt use their own OS from the outset?  Saying "it was easier to use Cromwell" will only suggest it was a rush job.

3) My bad, thought the *OZ(xodus?)*_paulb indicated he is/was associated.  *shrugs*

1) Maybe instead of being released to fob everyone off, it was released to comply with the requirements of the GPL.

2) Yes it did answer the question.  I fail to see how using existing code is "a rush job".  Certain goals were met using cromwell as a pseudo kernel for the 1.x xenium os's.   The desired features for the 2.x series were WAY past what cromwell could ever provide.  Hence the reason for the rewrite.

3) Oz generally refers to australia  Not OzXodus.  You probably should lay off the conspiracy theories if you don't even know who works for who.

I have no connection with any modchip company (other than occasional correspondence).

"oz" (in "oz_paulb") does in fact mean "Australia".  I'm not Australian, though - I created the 'handle' while I was vacationing there, and it just "stuck".

Here's a snippet of part of the "StartBios()" function from that date:

CODE

Here's a snippet of the current CVS version of "StartBios()" (checked-out today: June 2, 2004):

CODE

Now, here's a disassembly of the same code in SmartXX OS 3311 (of course, the function/symbol names were made by me, but I think it'll be clear that it's the same code):

I believe the similarities are clear so far.  But, let's follow it a bit further.

Andy wrote the ISO9660 code in Cromwell used for booting from CDROM.  This starts at the function "BootLodaConfigCD()" (note: this has since been renamed (spelling fixed) to "BootLoadConfigCD()").

Here's a dump of part of the current CVS version of "BootLoadConfigCD()":

CODE

ISO_PRIMARY_VOLUME_DESCRIPTOR * pipvd = (ISO_PRIMARY_VOLUME_DESCRIPTOR *)&ba[0];    char sz[64];    memset(&sz,0x00,sizeof(sz));    BootIso9660DescriptorToString(pipvd->m_szSystemIdentifier, sizeof(pipvd->m_szSystemIdentifier), sz);    VIDEO_ATTR=0xffeeeeee;    printk("Cdrom: ");    VIDEO_ATTR=0xffeeeeff;    printk("%s", sz);    VIDEO_ATTR=0xffeeeeee;    printk(" - ");    VIDEO_ATTR=0xffeeeeff;    BootIso9660DescriptorToString(pipvd->m_szVolumeIdentifier, sizeof(pipvd->m_szVolumeIdentifier), sz);    printk("%s\n", sz);    printk("  Loading linuxboot.cfg from CDROM... \n");        dwConfigSize=BootIso9660GetFile("/linuxboot.cfg", (BYTE *)KERNEL_SETUP, 0x800, 0x0);    if(((int)dwConfigSize)<0) // not found, try mangled 8.3 version  dwConfigSize=BootIso9660GetFile("/LINUXBOO.CFG", (BYTE *)KERNEL_SETUP, 0x800, 0x0);

Here's the same code in the current SmartXX OS "BootLodaConfigCD()":

This gets us to the ISO 9660 functions, written by Andy.  The top of "fs/cdrom/BootFileSystemIso9660.c" in the current CVS has the following notice:

Here's the source to "BootIso9660DescriptorToString()" from the same file:

CODE

void BootIso9660DescriptorToString(const char * szcDescriptor, int nLength, char * szStringResult) {    int n=0, n1=0, nLastNonspace=0;    while(n  if((n1!=0) || (szcDescriptor[n]!=' ')) {     szStringResult[n1++]=szcDescriptor[n];     if(szcDescriptor[n]!=' ') nLastNonspace=n1;  }  n++;    }    szStringResult[nLastNonspace]='\0'; }

Above, with just a small section of code, I believe I've shown that there is Cromwell code authored by Andy/Numbnut, released under the GPL, inside the SmartXX OS.  I've found similarities in several other sections of the code.  I haven't dug through 100% of the code, so don't know what percentage of SmartXX OS is Cromwell.


I'll eventually upload an ".idb" file (for IDA Pro) if anyone wants to take this further.

That's all for now...
