Jelly Bean 4.3 uImage, boot.img Issue

Former Member

Hi,


I hope someone can help me on this. This is for the Freescale IMX6Q tablet (Zenithink C-94). This really is a good tablet that never a chance. Originally came out with ICS 4.0 on it. Freescale released the source for Jelly Bean 4.3. I have built a rom from that source (and a AOSPA+ rom) , but the problem is with Zenithink. There are the proprietary blobs patched to the "boot.img" and "uImage_update". I need these blobs to get the tablet to initialize, but Zenithink hides behind a wall of silence. I have requested the source for the u-boot and boot.img, but have gotten squat. I have tried to pressure them by reporting a GPL violation here: license-violation@gnu.org and so far nothing. I have been left with reverse engineering this.

 

The "uImage_update" is essentially a uImage by what I can tell. On this tablet this writes to partition mmcblk08; basically a pre-file system that is up and running at initialization. The kicker is this is what I pulled off that:
Linux rev 1.0 ext4 filesystem data, UUID=80720123-59a2-fc56-b69d-aaf1e69ad9ae, volume name "vender" (extents) (large files)
This is a dev/zero section on that partition; meaning it overwrites the data from the first initramfs with zeros. Try to go into an adb shell:


# cat /dev/zero


and you'll see what I mean; you get nothing shown. I have extracted the initramfs from this uImage_update and this is what it looks like:

http://www.mediafire.com/download/6e30ctaz6ydn58t/initramfs_uImage.zip

This is very different from what I have seen. Check in the "res", "sbin", and "system" folders (also the "mkext2.sh). I then extracted and decompressed the .gzip data file out of the uImage_update and named it "update". I then typed:


$ binwalk update > update.walk


to get this:

This, as you can see, shows the cpio, kernel, gzip, and LZMA files. The .gzip here is the configuration file for the kernel. I did the same with the uImage I built, from the freescale ICS source. This was done so I could compare the to images to isolate the extra files from Zenithink. Then I compared the ICS source to the JB 4.3 source I built to see the changes from ISC to JB. The kernels are essentially the same. I know that threre will be a difference between the builds (ICS=GCC 4.4.3 and JB=GCC 4.6). I extracted these extra (.LZMA) files (binaries) from the original uImage_update to put into the JB uImage.

 

Next, was the boot.img to boot up the device. I have extracted the initramfs from that:

http://www.mediafire.com/download/5yj8mq7lw2grtlm/initramfs_boot.zip

As one can see, this is very different form the uImage_update. I followed the process as I did with above and I extracted the extra (.LZMA) files (binaries) from the original boot.img to put into the JB boot.img. So now you have a little history traveling down this rabbit hole, My question is:
How do I put these .LZMA files into the JB uImage (to be built and named "uImage_update") and JB boot.img? I do know it comes down to the uImage_update and boot.img to get this to work. I've tried updating the "initramfs" to match the way it is in JB, for both these images, but that did not work. I know someone here can help with this. Please help. Any and all help would be greatly appreciated.
Thanks,

    Dave,

    Have you considered that binwalk is lying to you?

     

    Take the LZMA data for example, the first part is


    10468824   0x9FBDD8   LZMA compressed data

    the last is


    12675172   0xC16864   LZMA compressed data

     

    so comparing the offsets you have a difference of 2,206,348 bytes

     

    Total up the reported uncompressed size of these and you get 15,587,317,941.  While a compression ratio of ~7000 to 1 isn't impossible, it seems implausible unless the data contained is essentially empty or otherwise very easily compressed.

     

    While it's by no means easy to draw conclusions from that, it seems much more likely that what you have is a uImage file that contains both an initramfs and a kernel. This is made more plausible by the following two lines:

     

    10454976   0x9F87C0   Linux kernel version "3.0.35 (android@amdroid) (gcc version 4.4.3 (GCC) ) #258 SMP PRersion 4.4.3 (GCC) ) #258 SMP PREEMPT Mon Nov 19 18:58:49 CST 2REEMPT Mon Nov 19 18:58:49 CST 20122012"

    11474468   0xAF1624   ASCII cpio archive (SVR4 with no CRC), file name: "oop (skipped) already calibrated this CPU"

    which look suspiciously like what you might find in a compressed kernel image.


    Have you tried feeding the file to u-boots mkimage with the -l switch to see if there are multiple files within the uImage, or running 'strings' against it to see if there are any obvious things that might give you a clue as to what it really is?

    Hi selsinork,

     

    Yes, in fact, there is the kernel and intramfs. Basically the "uImage_update" is a uImage and then there is a boot.img. I know both of these have the same kernel, and I do know that the kernel is patched with proprietary files (of which I cannot get from Zenithink). The "uImage_update" loads the vendor file and other stuff on mmcblk08. This I found in the initramfs of the uImage_update. Once this is loaded, then the boot.img comes into play for the actual booting of the device. The problem has been trying to get this updated to JB 4.3. My guess is that (from what I have read) the original uImage_update and boot.img are built with gcc version 4.4.3 and the new ones I built, are built with gcc version 4.6. These images are so close to being the same except for the proprietary files. I used binwalk more for comparison than anything else.  This was in a nutshell how I isolated these LZMA files. I did run a hex and strings on these files and I found, yes, these are the proprietary files. This has what lead me to the question of how to get these LZMA files into the uImage_update  and boot.img that I built. I am sure it can be done using the dd utility, but I am not sure how. I extracted these LZMA files from the decompressed kernels using the dd utility. They are here:

    http://www.mediafire.com/download/6s8ewdkplj17jkr/uImage_Adds.zip

    http://www.mediafire.com/download/dnij726c55of8s2/Boot_Adds.zip

    There are eleven for the uImage and eight for the boot.img. I have included the string and hex files with these. This whole thing would have been much easier if Zenithink would have provided the the sources I requested. What do you think?

  • 0 in reply to Former Member

    well yes, obviously easier of you have source... however that may or may not actually matter. It very much depends on what the files are. If you assume they're firmware that gets loaded into some piece of hardware by the kernel driver then it may not matter at all.

    If they are actual kernel modules that are only available in binary format then it's likely that you need both the exact kernel they were compiled for and to have compiled that kernel with the same compiler and the same arguments.

     

    However without some clue as to what they are and why you might need them, it's difficult to judge if they're even relevant.

     

    I'm not an android person, so this is about as far as I'm able to help.

    I agree. That is why I have been running these through IDA Pro. This is what helped get the information. I have extracted the kallsyms from the tablet so I can compare to the ICS source to make sure everything is like what I believe it is. This also will give me the addresses and symbols of the proprietary files. I am still back to the question of how to put these LZMA files into the new images. It is at least worth a try since the android kernel is nothing more then a patched Linux kernel.
