Hi.

Please tell me.

I follow the procedure below the website

but SGX Kernel Module Building issue stop the my project.

I have two questions about AM5728.Android SDK build

1.export path

SDK  not include arm-linux-androideabi-4.9.x-google files. 
Do I need to get it from anywhere?




2.lunch command
I see the below E2E comment.
e2e.ti.com/.../636081

Q.
Did you set ANDROID_ROOT, OUT_DIR and TARGET_DEVICE in your environment correctly?
A.

$ source build/envsetup.sh
$ lunch

Is this command the same as for AFS?

my case is

lunch am57xevm_full_userdebug

Correct?

Hello Takai,

Could you please share which PSDK Android you are using? In 5.2, the cross compiler will be "..android-devkit/arm-linux-gnueabihf-7.2.1/bin/arm-linux-gnueabihf-". In 4.0, the cross compiler will be "android-devkit/arm-linux-androideabi-4.9.x-google/bin/arm-linux-androideabi-" (Please refer to relevant Rules.make file)

In order to build the Android FS, please refer to the following threads: thread1 and thread2

Regards,

Krunal

Hi,Krunal.

Thank you for kindness.
I used sdk version 5.0.0.15. Your advice has been reflected.
But, I am still warned "Did you set ANDROID_ROOT, OUT_DIR and TARGET_DEVICE in your environment correctly?"
Is there a setting method"ANDROID_ROOT"　?

Hello Takai,

I do not see any warnings about ANDROID_ROOT, OUT_DIR and TARGET_DEVICE and please confirm the following build steps:

cd ~/<AFS_DIR>
export KERNELDIR=<path to kernel dir>
. build/envsetup.sh
lunch am57xevm_full-userdebug
make -j<x>

All my output files are located under <AFS_DIR>/out/target/product/am57xxevm.

Regards,
Krunal

Hi,Krunal.

I am confused.
Your procedure is an AFS build procedure, is not it?
I want to know "Building SGX Kernel Module"

Hi Takai,

In order to build the SGX Kernel module, please follow the following build steps:
1. Navigate to the folder "<AFS_DIR/vendor/ti/dra7xx"
2. git checkout git-ti-com/sgx-km-from-source
3. git checkout HEAD~1 (Ensure Commit ID=493daaec1e59310ccbd342fdd918d069e495b769)
4. Navigate to the folder "<AFS_DIR>" and make
