How to pack my own ZImage (kernel) to a new boot.img #2

Hi there

I can use your tools to unpack stock boot.img to zImage and ramdisk... then I can make change to ramdisk and then re-pack ok .... very good!!

unfortunately I have download kernel source and re-build (customize) my kernel and build new zImage

but I cannot pack my own (new) zImage and the ramdisk, I belive dt.img need to re-build....

can you tell me how to use your script to do that? it seems no paramter for me to pass dt.img path

大大, 簡單的是怎樣把我自己compile的kernel (zImage), 合拼ramdisk + dt.img 為boot.img ?
貌似dt.img 要compile過, 同時你的script不能指特定zImage 戓 dt.img
謝謝幫忙

###For example,e330s:

      page_size      : 2048
      base_addr      : 0x00000000
      kernel size    : 6911360
      kernel_addr    : 0x00008000
      ramdisk_size   : 2685222
      ramdisk_addr   : 0x02000000
      second_size    : 0
      second_addr    : 0x00f00000
      dtb_size       : 1427456
      tags_addr      : 0x01e00000
      cmdline        : console=null androidboot.hardware=qcom user_debug=31 maxcpus=2 msm_rtb.filter=0x3F

make recovery.img:

    mkbootimg_dtb --kernel zImage --ramdisk ramdisk.gz --base 0x00000000 --offset 0x02000000 --tags-addr 0x01e00000 --dt dt.img --cmdline "console=null androidboot.hardware=qcom user_debug=31 maxcpus=2 msm_rtb.filter=0x3F"  -o recovery.img

在你编译完内核以后，在arch/arm/boot/下，没有生成*.dtb文件？
如果有的话，直接运行：

    scripts/dtbTool -s 2048 -o arch/arm/boot/dt.img -p scripts/dtc/ arch/arm/boot/
    DTB combiner:

就可以生成dt.img
如果没有dtb文件，需要自己编译dtb文件：

    scripts/dtc/dtc -O dtb -o arch/arm/boot/msm8974-sec-ks01-r00.dtb -b 0  -d arch/arm/boot/.msm8974-sec-ks01-r00.dtb.d arch/arm/boot/dts/msm8974-sec-ks01-r00.dts

    scripts/dtc/dtc -O dtb -o arch/arm/boot/msm8974-sec-ks01-r01.dtb -b 0  -d arch/arm/boot/.msm8974-sec-ks01-r00.dtb.d arch/arm/boot/dts/msm8974-sec-ks01-r01.dts

Yes i has the following dtb files:

msm8974-v2-ef56s-pp10.dtb
msmsamarium-rumi.dtb

zImage

What is the param -p scripts/dtc/ ??? for

./dtbTool -s 2048 -o /usr/android/kernel/dt.img -p scripts/dtc /usr/android/kernel/obj/KERNEL_OBJ/arch/arm/boot

@hkfriends 我用你给的boot.rar成功生成了dt.img，命令如下，我在dtbTool里加了调试代码，终于发现是你的命令参数里的路径(-p scripts/dtc)有问题，需要改成-p scripts/dtc/。

你把dtcTool放在内核的scripts目录下运行试试吧，scripts/dtbTool

你要确定dtc所在的目录是否正确，dtc文件是否存在，dtb目录是否正确，*.dtb是否存在。

我上传了一个编译好的dtc文件，你可以放在一个目录下比如 /usr/android/下，运行：

你的dtc路径错了。
/xxxx/dtbTool -s 2048 -o /xxxx/dt.img -p /xxxx/dtc/ /xxx/kernel/arch/arm/boot/

这条命令要保证 /xxxx/dtc/dtc存在
/xxx/kernel/arch/arm/boot/*.dtb存在。

good... it is working :)

I tested either -p or without -p is ok (as I already installed DTC by apt-get install device-tree-compiler

the output parameter must ended with "/"

Many thanks^^

Ok , then how can i use this dt.img and with my own zImage + ramdisk ==>to make my boot.img?

Ok , then how can i use this dt.img and with my own zImage + ramdisk ==>to make my boot.img?

It seems your script "mkboot" has no such handling paramter:

repack boot.img：
mkboot [img] [ramdisk.gz or ramdisk dir] [newbootfile]
mkboot boot.img ramdisk newboot.img
unpack boot.img & decompress ramdisk：
mkboot [img] [output dir]
mkboot boot.img boot20130905

###For example,e330s:

make recovery.img:

    mkbootimg_dtb --kernel zImage --ramdisk ramdisk.gz --base 0x00000000 --offset 0x02000000 --tags-addr 0x01e00000 --dt dt.img --cmdline "console=null androidboot.hardware=qcom user_debug=31 maxcpus=2 msm_rtb.filter=0x3F"  -o recovery.img

it is strange:
my dt.img is based on my own zImage to build, now myboot.img should be ok to boot...
but i still got FAILED (remote: dtb not found)

./mkbootimg_dtb --kernel /usr/android/kernel/obj/KERNEL_OBJ/arch/arm/boot/zImage --ramdisk ./tmp/ramdisk.gz --base 0x00000000 --offset 0x02000000 --tags-addr 0x01e00000 --dt ./dt.img --cmdline "console=null androidboot.hardware=qcom user_debug=31 maxcpus=2 msm_rtb.filter=0x3F" -o myboot.img

H:\sdk>fastboot boot myboot.img

--offset 0x02000000 --tags-addr 0x01e00000 --cmdline 这几个参数需要从原版boot,img获取
./mkboot boot.img tmp就能获取到

I upload my files
zImage ==> my own zImage
dt.img ==> this dt.img is based on same (zImage+DTB) to build
myboot.img

This is the stock boot.img (good image from original)

我对比了两个boot.img，官方用的dt和你的不太一样，建议你使用官方的dt.img+你的zImage+ramdisk打包试试

@hkfriends 官方用的是tp20.dts ，开源内核里编译用的是pp10，是不是这个原因呢。

官方的dt.img+new zImage+ramdisk打包 ==> OK

but another problem... now my device is very slow....... not normal
I think the dt.img is not good for my new kernel zImage

@hkfriends

i think i need to build my own dt.img
but my own dt.img is not able to boot

what is the diff of tp20.dts and pp10

@hkfriends 你把编译得到的 *.ko放在/system/lib/modules/下了吗？
你的手机很慢和dt（device tree）应该没有关系的，可能是源码给的是比较老的，没有更好的优化过。

TP20为主板的硬件版本，可以拆机查看主板，例如A840工程机主板型号WS20
20130529093125138

或者在/system/build.prop中可以找到ro.product.board_ver=TP20

从build.prop得出A880正式机主板型号为TP20，而其它型号可能为工程机。

在内核源代码include\pantech\BOARD_REV.h中指定需要编译的主板型号
#define PT10 0X0010
#define PT20 0X0020
#define WS10 0X0030
#define WS20 0X0040
#define TP10 0X0050
#define TP20 0X0060
#define PP10 0X0070

#define BOARD_VER TP10 (官方提供的源代码为TP10，可能用来测试工程机的，自己编译时应该改为TP20)

理解 , 讓我再試一次. 以前编译 a850,860,870 沒有這樣的問題..

我这里运行dtbTool时发现这一句：
/* Open the .dtb files in the specified path, decompile and
extract "qcom,msm-id" parameter
*/
while ((dp = readdir(dir)) != NULL) {
if ((dp->d_type == DT_REG)) {
上面这个if判断会导致无法识别我的dtb文件，注释掉这个判断就OK，求解：这个DT_REG是什么？在何处定义的？

@ziyouwa
DT_REG 在 /usr/include/dirent.h定义。
表示这个是个常规文件，不是目录，不是符号链接，不是设备。

@xiaolu 谢谢！还是不明白为什么识别不正确，的确是常规文件

Hello @xiaolu! I compiled dt.img from my msm8226-g2mds.dtb file in /arch/arm/boot/. But after I repacked boot.img and replaced dt.img in it and flash my phone did not boot! If I repack boot.img with stock dt.img phone working. In what can be problem?
This is my kernel sources: https://github.com/NikitaProAndroid/android_kernel_lge_msm8226_g2mds/tree/cm-12.x
My stock dt.img: https://yadi.sk/d/0N-k6tK2g38ys
My own compiled dt.img: https://yadi.sk/d/li7GgtCQg396M

And what is VERy strange - they have the same size in bytes!!
But with stock phone starting, with my - not starting...

I fix this problem using dtbToolCM with -2 parameter.

@ziyouwa 我发现，在我的电脑分区文件系统为reiserfs时，d_type始终为0。那么，很可能是文件系统的问题。

@xiaolu I am tried for a long time with this tool.
I failed and failed to create dt.img using dtbTool.
Today I tried dtbToolCM and it creates the dt.image succesfully.

  • what is the difference of dtbToolCM and dbtTool ?
    Thanks
