AM335X starter kit Android kernel build



Hi all,

I found a page: http://processors.wiki.ti.com/index.php/TI-Android-JB-4.1.2-DevKit-4.0.1_DeveloperGuide

It is quite easy to follow but a few questions I had in mind and I would like to get some clarification from experts!

1. I can manually build

a. the U-boot (Actually is uboot + xloader, am I right).

b. the kernel.

c. the Android File System.

2. If it is 'yes' for the above question, then what is the point to have this "Filesystem without SGX" step in the wiki?

a. If I want to use SGX 3D accelerator then I have to skip this step mentioned in the wiki, am I right?

b. If I want to use SGX 3D accelerator but I only want to compile the Android File System, what command should I used? 

 make TARGET_PRODUCT=am335xevm OMAPES=4.x -j4 (As I know this is to make a fully system build included Kernel + other modules)

- $ make TARGET_PRODUCT=am335xevm_sk droid kernel_build wl12xx_compat -j<N>  (This look more individual built but it is under "Filesystem without SGX" topic)

3. So if I have modify my kernel or using different wifi module, what command line I should used to build module and Android file system?

Please advice. Thank you very much!
