Compiling custom modules... failed to insmod

Hi,
I am trying to make custom mtd module, to expand the mtd devices to read whole nand and i am using as an example msm_nand.c
So what i have done is added a few devices to mtd partition and compiled. But at the compilation ld says msm_dmov_exec_cmd in not found.. Does not sound good, because original msm_nand.c compiled good as well as the whole kernel.
Could someone help me?
Here is the code i added, i left last lines from the original and my addition due to the code length restriction here:
Code:
/* drivers/mtd/devices/msm_nand.c
.....
msm_nand_release_ex(&info->mtd);
dma_free_coherent(/*dev*/ NULL, SZ_4K,

kfree(info);
}

And also i get in dmesg weird message that my kernel version string is wrong, though i used same kernel except the last modification string. And i can't find any other kernel..
Thanks guys!

you should edit the Makefile and set
EXTRAVERSION = <your kernel version>.

Yes i managed to bypass it but the insmod then says msm_dmov_exec_cmd is not found..
Weird..

[?]How to read binary file in xna?

I need read 10 byte in fileName and save it into bitLevel
My code:
PHP:
test = 0;
byte[] bitLevel = new byte[10];
string fileName = "levels\\";
switch(iChap){
case 1: fileName += "beginner.dat";
break;
case 2: fileName += "normal.dat";
break;
case 3: fileName += "intermediate.dat";
break;
case 4: fileName += "expert.dat";
break;
}
using(FileStream fileStream = new FileStream(fileName, FileMode.Open, FileAccess.Read))
{
fileStream.Seek((iLevel - 1) * 10, SeekOrigin.Begin);
fileStream.Read(bitLevel, 0,10);
test = 1;
}
but bitLevel is empty
It seem it's not into codes under using, because I set test = 1; but it = 0;
can anybody help me?
//sorry my bad english

Use IsolatedStorageFile & IsolatedStorageFileStream instead of FileStream.

is that ok?
can you show me demo code?

Code:
using (IsolatedStorageFile isf = IsolatedStorageFile.GetUserStoreForApplication())
try
{
using (IsolatedStorageFileStream inStream = new IsolatedStorageFileStream(fileName, FileMode.Open, isf))
{
byte[] buffer = new byte[10];
int numRead = inStream.Read(buffer, 0, 10);
Debug.Assert (numRead == 10);
}
}
catch (Exception e)
{
Debug.WriteLine(e.Message + "\n" + e.StackTrace);
}
But this code for ISF only; I don't really know where are your files located (as resources or may be content). You should understand what are you trying to read first
If you added these files as a content to your project, you should read 'em from the TitleContainer
Code:
using (var inStream = TitleContainer.OpenStream(fileName))
using (StreamReader streamReader = new StreamReader(inStream))
... and so on...

Android 4.2 Change Default orientation to Portret

Hi!
I`m porting Android 4.2.2 to my Device, and have a problem with screen default orientation!
Code:
public DisplayDeviceInfo getDisplayDeviceInfoLocked()
{
String str;
if (this.mInfo == null)
{
this.mInfo = new DisplayDeviceInfo();
this.mInfo.width = this.mPhys.width;
this.mInfo.height = this.mPhys.height;
this.mInfo.refreshRate = this.mPhys.refreshRate;
if (this.mPhys.secure)
this.mInfo.flags = 12;
if (this.mBuiltInDisplayId != 0)
break label264;
str = SystemProperties.get("ro.sf.hwrotation");
this.mInfo.name = LocalDisplayAdapter.this.getContext().getResources().getString(17040667);
DisplayDeviceInfo localDisplayDeviceInfo = this.mInfo;
localDisplayDeviceInfo.flags = (0x3 | localDisplayDeviceInfo.flags);
this.mInfo.type = 1;
this.mInfo.densityDpi = (int)(0.5F + 160.0F * this.mPhys.density);
this.mInfo.xDpi = this.mPhys.xDpi;
this.mInfo.yDpi = this.mPhys.yDpi;
this.mInfo.touch = 1;
this.mInfo.rotation = 0;
if (!"270".equals(str))
break label224;
this.mInfo.rotation = 3;
}
while (true)
{
return this.mInfo;
label224: if ("180".equals(str))
{
this.mInfo.rotation = 2;
continue;
}
if (!"90".equals(str))
continue;
this.mInfo.rotation = 1;
continue;
label264: this.mInfo.type = 2;
this.mInfo.name = LocalDisplayAdapter.this.getContext().getResources().getString(17040668);
this.mInfo.touch = 2;
this.mInfo.setAssumedDensityForExternalDisplay(this.mPhys.width, this.mPhys.height);
if (!"portrait".equals(SystemProperties.get("persist.demo.hdmirotation")))
continue;
this.mInfo.rotation = 3;
}
}

[MOD][CM12][COLOROS 2][HYDROGEN OS] Splash Screen Image Injector v1.2

This is a program that I wrote to decode the newer style "logo.bin" files used in some OPPO, and OnePlus devices. Please read below so you can better understand this type of encoding being used:
What Is A Raw Image?
A raw image, whether it be a file or an image in memory, is simply pixel data. There is no extra information like width, height, name, end of line... Absolutely nothing, just pixel data. If you have an image that is raw and the resolution is 1080x1920 and you are using a typical RGB24 or BGR24 (like the ones used here), then your exact filesize or size in memory will be 1080x1920x3! We use 3 here because there is one byte for the R or red component, one for the G (green), and one for the B(blue).
What Is A Run Length Encoded Image?
A run length image encoding uses a count ;usually a single byte (char), 2 bytes (short int), or 4 bytes (long int); and then the pixel components. So instead of writing out 300 bytes of '0's to make a line of 100 black pixels. Black is RGB(0,0,0). You could encode this as 100, 0, 0, 0. And only use 4 bytes of data to get the exact same image as the 300 byte raw image. All the run length encoding I've found, except the Motorola style which is a little different, use a run length encoding that is pixel-oriented like this.
Now I've figured out this new one and it is a byte-oriented run length encoding. This is for runs of bytes, not pixels. You may think, well whats the big deal? When you add a little area of color, you increase the run length encoded image in you logo.bin immensely! You use 6 bytes per pixel if there aren't any runs of color data. If you had an image that was a 1080x1920 black image with a 25 pixel wide, by 25 pixel high red box in the middle. The encoder would be doing runs of black data efficiently until it reached the red area.
.....0 255 0 255 0 255 0 255 0 255 0 99 /// we've reached the top left corner of the red square /// 13 1 30 1 255 1 // << that was just one red pixel!! in bgr color order (13, 30, 255) <<// And it keeps going through the rest of the red pixels on that line using 6 bytes per pixel, which is the opposite of compression. Before reaching the red square the encoding was decoding to 255 zeros over and over, until finally 99 zeros. 255 zeros is 85 black pixels stored in just 2 bytes!
This type of encoding is only good for grey scale images. It is not good with color, but it still will handle color of course. In grey scale, the Red, Blue, and Green data components are always the same values. All the way from black (0,0,0) to white (255, 255, 255); including every shade of grey in between>>>(1,1,1) (2,2,2) (3,3,3)....(253, 253, 253) (254, 254, 254)<<<
One other difference in this method of run length encoding is that the color byte is before the count, which is backwards from all of the other methods.​
The attachment contains the C source code (which is also in the 2nd post) and the executable that was compiled using mingw32 on a 64 bit Windows 7 PC. The PNG library that I used is LodePng, the source is in the download.
To use logoinjector:
Decode your logo.bin:
Code:
logoInjector.exe -i logo.bin -d
All the PNG 's will be extracted from logo.bin. Edit the PNGs that you want to change...
Note:
Your original "logo.bin" file is never changed, it is just read. If the file you try to load isn't a logo.bin file, or if it is the older style, then the program will tell you and exit​
Inject the image(s) back in to the logo.bin:
Code:
logoinjector.exe -i logo.bin -j image_name_1 image_name_3....
To list whats in your logo file:
Code:
logoinjector.exe -i logo.bin -l
For a more detailed list:
Code:
logoinjector.exe -i logo.bin -L
If the colors are messed up use the "-s" switch while decoding.
Code:
logoinjector.exe -i logo.bin -d -s
If you had to use the "-s" switch to decode properly, you'll have to use it to inject also:
Code:
logoinjector.exe -i logo.bin -j image_name -s
Note:
With version 1.2, you can put as many names after "-j" as you want, and it's not case sensitive. You also don't have to put the whole name. If you just put "-j fhd" every image in the logo.bin that starts with "fhd" will be injected. There has to be a PNG with the name in the directory though​
The size of your modified.logo.bin will displayed along with the original size, if everything went good. Please know the size of you logo partition. I made this program to encompass any device using this format, and there is no set size of the logo partition between devices. Fastboot will just error out if you try to flash data bigger than the partition before it writes anything. But if someone gets brave and tries to "DD" to the logo partition, it could get ugly.:cyclops:
Flash the "modified.logo.bin" file through fastboot.
v1.2
made it possible for multiple injections in one command
doesn't add png to the decoded png if it was already in the name
fixed out of scope with image 26 in OPPO find 7 logo.bin
added LodePng source in the download
made the default color order BGR
displays the modified logo file size as well as the original file size
runs the modified.logo.bin back through the list function after injecting
checks the number of offsets between the original and modified logo.bin
Use this at your own risk.
Always make backups.
Always.

Interesting Can you tell me where do I find the logo.bin in my boot.img. I've extracted mine and don't see any sign of logo.bin. I own a OnePlus 2

Did you download a system image? If so, unzip it, and look for the folder "firmware-update". The logo.bin should be in there.

Works well for me! Thanks!

Thanks!! Removed this:
This is untested on the oneplus 2, however I've looked at the logo.bin from your firmware and it is identical to the newer oneplus one logo.bin. Let me know! Thanks!​

how did you flash your modified logo.bin? if done through "fastboot flash logo logo.bin" it just quits with this error:
Code:
target reported max download size of 536870912 bytes
sending 'logo' (1581 KB)...

this also happens with an unmodified logo.bin

You have to flash "LOGO" partition and not "logo"

gotta love case sensitivity. thanks, it worked.
awesome mod

It worked, thanks

This will work with Stock Oneplus 2 rom too, right?
Edit:
Working fine with my Onelus2 too, just got logo.bin from my stock Oxygen rom. Thanks again.

From where can I extract my logo.bin from my phone? I dont have the stock rom with me. I need this from 1+2 if this works with it?

I went into changing the splash screen only after I'd already changed to custom rom ( bliss 6 ), so I didn't had any official OPT rom zip.
I tried to use the "logo.bin.p" from latest OTA updates FROM HERE... but the LogoInjector telling me that "This is NOT a valid Logo.bin".
Solution I found -> I managed to EXTRACT THE LOGO.BIN FILE FROM THE OPT ITSELF !!!
I got it right after I read about this command and saw the "updater-script" from one of the official OTA updates that included a hint about logo.bin place in the OPT internal storage :
apply_patch("EMMC:/dev/block/bootdevice/by-name/LOGO:305152:567b5d4deed7f4875809ae8b7f071ab38e5a94d5:305152:16c76f9c0cadf8be18eed0961dfbcf3b7bd0aacf",
"-", 16c76f9c0cadf8be18eed0961dfbcf3b7bd0aacf, 305152,
567b5d4deed7f4875809ae8b7f071ab38e5a94d5, package_extract_file("patch/firmware-update/logo.bin.p"));
Click to expand...
Click to collapse
so... how to extract to logo.bin ?
Note: If you don't know what you're doing - DO NOT DO IT ! DD command is DANGEROUS !
Using adb open shell and run the following command:
dd if=/dev/block/bootdevice/by-name/LOGO of=/sdcard/logo.bin bs=305152 count=1
Click to expand...
Click to collapse
This will create a "logo.bin" file inside the root of your internal memory aka /sdcard folder.
I got from that the following image files list:
Resolution - Offset - Name
1080x1920 | 0............ | fhd_oppo_1080_1920_result.raw ---> THE SPLASH IMAGE !!!
536x60.........| 65536 | fhd_at_536_60_result.raw
300x1020....| 75264 | fhd_charger_300_1020_result.raw
1080x1920 | 89600 | fhd_fastboot_1080_1920_result.raw ---> THE FASTBOOT IMAGE !!!
1080x1920 | 145920 | fhd_lowpower_1080_1920_result.raw
392x66 ........| 277504 | fhd_rf_392_66_result.raw
487x69 ........| 285184 | fhd_wlan_487_69_result.raw
Note, inorder to load the png to the logo.bin you need to rename the png you make as *.raw according to this list above.
Now... inorder to "flash" the logo.bin back to the OPT I use the attached zip.
you only need to add "logo.bin" to the root of this zip, then flash it through TWRP.
@makers_mark - once again, after your OPO development - Thanks A LOT for developing & sharing with us LogoInjector for the OPT as well

@makers_mark
Could you make one for oneplus3?
Thanks in advance.
logo.bin for oneplus3 is attached.

Samsung Galaxy Core Plus (G350 / CS02) CWM & CyanogenMod development

Hey,
I think we have completely stolen the other thread about CWM for our device (SM-G350).
So I started a new one dedicated to development of this phone.
Currently I'm trying to port CyanogenMod 10.1 (4.2.2JB) from Trivalent's source code in GitHub. (Thanks to warlinegtr for finding it)
IF you have any skills that might help with this project, please contact me.
And please don't post links to some basic tutorials, I have already read them.
You can freely post source code that might help us in the future.
Regards, santeri3700

Status 12.9.2015 (DD/MM/YYYY)
Current issue: CM10.1 Cannot boot because of the wrong CWM made for cm_mint. It overwrites init.rc and adds wrong fstab to the system partition.
My own built CWM has graphical bug. Half the screen is black and other half is stretched and pink-ish. Still possible to operate.
