How to build a unique SDK for custom board by i.MX6 Android BSP.

[satoshishimoda]

Hi community,

I have a question about i.MX6DL Android BSP (jb4.3_1.1.0-ga).

Our partner tried sdk buiding by following procedure, but it failed with the attached error log.

[Procedure]

1. Do the procedure from chapter 2.1 to 3.2 written in Android User's Guide (Rev jb4.3_1.1.0).

2. Execute the following command.

make sdk -j4

Actually, our partner should provide a unique SDK for custom bord to a application software vendor.

You know Google releases Android SDK, but it is not used for the custom board because the Android framework expansion is required in this case.

Then, please see my request as below.

[Q]

Could you let me know how to avoid this error?

And if there is other method to prepare unique SDK, could you let me know it, too?

Best Regards,

Satoshi Shimoda

Hi Satoshi,

I decide to make patches for this and will push the code to our default release. You can refer to the patches in attachment.

Hi Jay Tu,

To make sure, could you reply to the following questions?

[Q1]

I think I should apply the patches without the following modifications, is this right?

=====

1.

-LOCAL_MODULE_CLASS := ETC

+LOCAL_MODULE_CLASS := ETC_WPA

2.

-LOCAL_MODULE_CLASS := ETC

+LOCAL_MODULE_CLASS := ETC_DHCPCD

3.

libnetlink \

     libnetutils \

-    libreference-ril \

     libreverbwrapper \

     libril \

=====

[Q2]

To accommodate your and our environment to apply the patches, could you let me know the directory and command?

The following understanding is correct?

=====

0001-ENGR00309037-Fix-sdk-build-fail.patch :

directory :  external/wpa_supplicant_8

command : patch -p1 < 0001-ENGR00309037-Fix-sdk-build-fail.patch

0001-ENGR00309037-1-Fix-sdk-build-fail.patch :

directory : hardware/ril

command : patch -p1 < 0001-ENGR00309037-1-Fix-sdk-build-fail.patch

=====

Q1: Yes

Q2: git am xxx.patch

[satoshishimoda]

Thank you for quick response.

But sorry, I don't understand how to use "git am" command.

Should I execute it on appropriate directory?

Or can I execute it on any directory?

Best Regards,

Satoshi Shimoda

[JayTu]

You need execute it on appropriate directory.

[satoshishimoda]

The appropriate directories are following?

0001-ENGR00309037-Fix-sdk-build-fail.patch

=> external/

0001-ENGR00309037-1-Fix-sdk-build-fail.patch

=> hardware/ril

[JayTu]

0001-ENGR00309037-Fix-sdk-build-fail.patch

=> external/wpa_supplicant_8

0001-ENGR00309037-1-Fix-sdk-build-fail.patch

=> hardware/ril

Hi Jay Tu,

I tested the patches.

Unfortunately, build was failed with the following error even though I checked the patches were applied certainly before building, and tried build without the above three modifications.

[JayTu]

Please find the patch, it had new realtek driver and config directory is removed. So the error isn't shown on my environment.

Procedures

1. cd hardware/realtek
2. git am 0001-ENGR00290615-Wifi-enable-wifi-on-KK4.4.patch

[satoshishimoda]

After I copied version.h from jb4.2.2_1.1.0, the error seems be resolved, but a new error was occurred as attached.

How avoid this error?

javadoc: command not found

You can check if you have javadoc command, should be in your jdk folder.

[satoshishimoda]

Hi Jay Tu,

I have installed javadoc as the attached image with How to install Sun's JDK in Ubuntu for Android build.

However, the javadoc error was occurred.

Then, the error was resolved after the following command.

export PATH=$PATH:/opt/java/64/jdk1.6.0_45/

The build  result was the following image.

I think build was finished correctly, do you think so?

[JayTu]

Yes, I think so.

[satoshishimoda]

After apply the patch, the error was not occurred.

However, the version.h error I mentioned the above was occurred again even though I remade a build environment with Android User's Guide (Rev.jb4..3_1.1.0).

So I copied version.h from jb4.2.2_1.1.0.

Do you think this is appropriate solution?

Best Regards,

Satoshi Shimoda

[satoshishimoda]

Hi Jay Tu,

Thank you for releasing the patches.

I will check sdk build with them.

Just a moment, please?

Best Regards,

Satoshi Shimoda

[JayTu]

Try:

lunch sdk-eng

make sdk

[satoshishimoda]

Hi Jay Tu,

I got a report from our partner.

Unfortunately, "make sdk" stopped with the attached log even though they added "lunch sdk-eng" before "make sdk".

Could you let me know what should they check next?

For your information, the partner execute "source build/envsetup.sh" before this sdk build as below.

$ source build/envsetup.sh

$ lunch sdk-eng

$ make sdk -j4

Satoshi Shimoda

[JayTu]

So now your error is different,

build/core/base_rules.mk:130: *** external/wpa_supplicant_8/wpa_supplicant: MODULE.TARGET.ETC.wpa_supplicant.conf already defined by external/wpa_supplicant_8/wpa_supplicant.  Stop.

It's because wpa_supplicant.conf is defined twice.

[satoshishimoda]

Hi Jay Tu,

Thank you for your reply.

I understand what is mentioned the error message.

Then, could you how to avoid this error?

I did 'grep -r "wpa_supplicant.conf" .' on external/wpa_supplicant_8/wpa_supplicant directory, but I did not understand what line should I comment out because a lots of lines include "wpa_supplicant.conf".

Best Regards,

Satoshi Shimoda

[JayTu]

In external/wpa_supplicant_8/wpa_supplicant, Android.mk and wpa_supplicant_conf.mk both had the following definition:

Android.mk:LOCAL_MODULE_CLASS := ETC

You can try to rename it in wpa_supplicant_conf.mk like,

-LOCAL_MODULE_CLASS := ETC

+LOCAL_MODULE_CLASS := ETC_WPA

It is similar as Android 4.3 "make update-api" error
