Unable to find firmware in the file.

Hi,

As the software say, please report the driver file (preferabiliy by private mail) plus machine and OS description.

Regards,
Étienne.

Same driver file here, MacOS X 10.6.2 on a MacBook Pro 2.

Ubuntu Karmic x86, MacOS 10.6.2, isight-firmware-tools-1.5.90

** (ift-extract:10598): WARNING **: Unknown driver.

I have the same problem (as above reported by other people).

My system is: Apple Aluminium iMac 7.1 24" (cpu Intel Core 2 Duo @ 2.4GHz 64bit)
My Mac OS X version is: 10.6.2
My Linux Ubuntu distro is: 10.04 Alpha 3
My isight-firmware-tools package version is: 1.4.2-3

I will not attach any firmware file, since mines is exactly/binary equal to the above ones (i checked the one ulpoaded by xx user).

Here it is the terminal output for this command:
          ift-extract -a /media/Poesia/System/Library/Extensions/IOUSBFamily.kext/Contents/PlugIns/AppleUSBVideoSupport.kext/Contents/MacOS/AppleUSBVideoSupport

** (ift-extract:20195): WARNING **: Unknown driver. Please report it to https://bugs.launchpad.net/isight-firmware-tools/+filebug with machine description and Mac OS X version.

** ERROR **: Unable to find firmware in the file.
aborting...
Trace/breakpoint trap (core dump creato)

Other driver (md5sum: f023f4c062081c4091c3eff865e66602), but same problem: no firmware found.

MacBookPro6,2, MacOSX 10.6.3

Hi, same as bug #487330. The firmware is declared half sized. That should be an update of 10.6.2.

Hi,

Can you try 10.6.3 driver with ift-extract 1.5.91 ?

Étienne

Sure, no problem! I just cannot find the new version on launchpad:
https://launchpad.net/isight-firmware-tools/+download .

And please note that on my firmware, my 'tool' gives about 20
possibilities. I do not yet know how to find the correct one. Could
you help me perhaps? I had some trouble understanding the directions
in extract.c, and I assume you do understand them. This is the hint on
where to find the firmware in extract.c:

  * If a file does not work, you may need to add an entry here. To find
  * the offset in the driver file, use a hexadecimal editor (e.g. ghex)
  * and search for "USBSend". You will find data like this :
  *
  * "start USBSend #4 returned 0x%x.....X.....4.~.........%\"
  * ^
The thing is, I cannot find this complete, exact string.

I was experimenting with the offset from the other patch in Launchpad
for MacOSX.6.3. That offset happens to 'work' for me (the firmware
extractor extracts something from that offset), but I'm not sure that
offset is correct. Using an hex-editor, I end up 5 characters before
the '%\', just as indicated in extract.c . Is this the way to go:

- find the sentence 'start USBSend #4 returned'
- find the next occurrence of '%\'
- count back 5 bytes.

Hi Étienne!

Thanks for your reply - I appreciate it! I have just cloned your tree
and built it on my newly install lucid machine. This is the output I
got:

sudo ift-extract -a
/media/hd/System/Library/Extensions/IOUSBFamily.kext/Contents/PlugIns/AppleUSBVideoSupport.kext/Contents/MacOS/AppleUSBVideoSupport
** Message: Found firmware signature at offset 0x2010.

** ERROR **: Invalid firmware data_length 16453, load aborted
aborting...
Aborted

My osX install is 10.6.3 - no updates available and I am using a new
lucid 64 bit install. I will be happy to try whatever needed.

Thanks!

Hi,

That should be fixed in latest 1.5.92 :)

Actually, Apple did an update on the firmware. I now guess the version bytes in the head of the firmware. I added a tests/Makefile.am to run ift-extract on all the driver i collected so far. Everythings looks good.

While debugging stuff with linux UVC driver maintainer, i added 3 fixes to the firmware USB self publishing. So everyone is encouraged to update. That may increase quality. All fixes apply to both old and new firmware.

Thanks for the report and help.

Regards,
Étienne

Hi Etienne,

You've been busy! This seems like much more user- (and maintainer- :)) friendly version! Extracting seems to work for my driver, as a firmware file of 10852 bytes is extracted (fw version 2.38.83). Does that make sense to you?

I tried programming the firmware anyway, without actually running 'make install':

user@laptop:~/projects/isight-firmware-tools-1.5.92$ sudo ./src/ift-load --firmware isight.fw
ift-load: USB device 0x05AC:0x8300 not found
ift-load: No iSight found
user@laptop:~/projects/isight-firmware-tools-1.5.92$

It seems the device code has been changed for the new macbooks pro, so I've attached the relevant part of 'sudo lsusb -v'.

Note that I spotted various typo's in the ift-export manpage, you might want to have a look at those before a next release.

Thanks for the credits,

Jeroen.

Works perfect!

Thanks!
Yuval

Hi,

Actually, i will release it as 2.0. The change is quite substancial.

The product id is supposed to be exposed by the firmware. Can you check
you're firmware has "AC 05 01 85" and not "AC 05 07 85" at offset 0x2356
of your firmware (or send it).

I'll check this. I updated the website (2 years without update). And
translations have to be updated too.

Étienne
