TI-Android-JB-4.2.2-DevKit-4.1.1 guide issue

Maxim Podbereznyy

Hi!

I'm trying to build TI-Android-JB-4.2.2-DevKit-4.1.1 for am335EVM. What I did:

1) Installed Ubuntu 14.04 with required software

2) downloaded [http://downloads.ti.com/sitara_android/esd/TI_Android_DevKit/TI_Android_JB_4_2_2_DevKit_4_1_1/exports/TI_Android_JB_4.2.2_DevKit_4.1.1.bin]

3) installed it

the following steps are based on the guide processors.wiki.ti.com/.../TI-Android-JB-4.2.2-DevKit-4.1.1_DeveloperGuide

4) export PATH to gcc... works

5) make TARGET_PRODUCT=am335xevm OMAPES=4.x -j4 sdcard_build

I can see how u-boot and kernel have been built, but your guide states the following:

This command will build boot loader, kernel and filesystem with SGX for the specified product name

everything builds without any errors and now I expect to see anything in out/target/product/am335xevm, but this directory is absolutely empty. What should I do next to have u-boot, kernel and SGX drivers in there?

Hello,

Android must be built prior to build kernel.
It turns out that the rule sdcard_build will first build the kernel without detecting if Android was built or not.

To workaround this:

1) please build without the sdcard_build parameter first:
$ make TARGET_PRODUCT=am335xevm -j4 OMAPES=4.x

2) After it built successfully, then build with the sdcard_build parameter
$ make TARGET_PRODUCT=am335xevm -j4 OMAPES=4.x sdcard_build

If this still doesn't work, try the same commands but without "-j4", to prevent parallelization problems.

Hi!

Thank you for the answer!

I've started the full build, but actually I need only u-boot, kernel, SGX and wifi drivers because there is a prebuilt filesystem publicly available:

downloads.ti.com/.../TI_Android_JB_4.2.2_DevKit_4.1.1_am335xevm.tar.gz

what should I do to have firmware built and placed to necessary directories? I'm going to use the ready filesystem image

Hello,

TI_Android_JB_4.2.2_DevKit_4.1.1_am335xevm.tar.gz contains everything to prepare a SD card, extract this archive and use "mkmmc-android.sh"

Otherwise, the build procedures for the different parts are detailed here: processors.wiki.ti.com/.../TI-Android-JB-4.2.2-DevKit-4.1.1_DeveloperGuide

If you need to replace u-boot, once recompiled, go to u-boot/, you should copy MLO and u-boot.img to "Boot_Images" (replace the existing files) and use "mkmmc-android.sh"
If you need to replace the kernel, once recompiled, go to kernel/arch/arm/boot/, you should copy uImage to "Boot_Images" (replace the existing file) and use "mkmmc-android.sh"
