OpTEE + Android in Hikey960

Try flashing the boot.img you had built earlier using the instructions from https://github.com/vchong/optee_android_manifest/blob/wip/tmp.txt.

Boot failed after flashing the boot.img

Failed how? Anyway, going through the source code the boot.img from step 1 above should have worked as well. Did you do “Building the kernel” from https://source.android.com/setup/build/devices#960hikey?

Hi @vchong
I did the following and not able to bring up the HiKey960 board using OP-TEE with AOSP

1. Build aosp for hikey960 based on https://source.android.com/setup/build/devices#960hikey. 
	Boot successful without OP-TEE.
2. Build AOSP with OP-TEE using  https://github.com/linaro-swg/optee_android_manifest/tree/lcr-ref-hikey-o 

and device/linaro/bootloader/arm-trusted-firmware, device/linaro/hikey/uefi-tools, device/linaro/bootloader/edk2, device/linaro/bootloader/OpenPlatformPkg from #1
3. Flash fip.bin & boot.img from #2 but boot failed

4. Building the kernel from https://source.android.com/setup/build/devices#960hikey2? on #2 environment
	Then executed steps at #3 but the result is same

Don’t use the boot.img from #2. Use the boot.img from #1 environment. If you build the kernel, also build it in the #1 environment.

Hi @vchong thanks for your help.

Finally able to boot the hikey960 board using OP-TEE with AOSP.

  1. Recovery from tools-images-hikey960
    https://github.com/96boards-hikey/tools-images-hikey960

  2. Flash reference build
    https://snapshots.linaro.org/96boards/reference-platform/components/uefi-staging/69/hikey960/release/
    Install UEFI on HiKey960 from Binaries [Instructions]

  3. fip.bin from Fresh build…
    https://github.com/OP-TEE/build

  4. Boot and System images from AOSP960 build
    https://source.android.com/setup/build/devices

  5. Build latest boot image using updated kernel
    https://source.android.com/setup/build/devices

  6. xtest, tee-supplicant and .ta from build https://github.com/linaro-swg/optee_android_manifest/tree/lcr-ref-hikey-o

But getting the error while running the xtest

console:/ # xtest 200

You’re welcome! Good job putting the pieces together and thanks for sharing!

Din you run xtest as root? In yes, then try adding these selinux policies:
https://android-review.linaro.org/#/c/17177/12/sepolicy/file_contexts
https://android-review.linaro.org/#/c/17177/12/sepolicy/tee.te
https://android-review.linaro.org/#/c/18062/2/sepolicy/tee.te

Now xtest is running OK except the following few test cases related to SDP

For xtest 200, did the selinux policies help?

Sigh, one more missing piece. The kernel you specified in

  1. Build latest boot image using updated kernel
    https://source.android.com/setup/build/devices

is not fully patched for SDP, i.e. missing CFG_* for SDP in the defconfig and etc.

Try this. Run https://github.com/linaro-swg/optee_android_manifest/tree/lcr-ref-hikey-o until step 3.4. Then stop. Next cd to kernel/linaro/hisilicon. After that:

make ARCH=arm64 hikey960_defconfig
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-android- -j24

After that, continue with step 2 and 3 in the ‘Building the kernel’ section of https://source.android.com/setup/build/devices#960hikey. In step 2, make sure you copy hi3660-hikey960.dtb and Image file over to the hikey-kernel directory of your hikey960 aosp source tree! Then run step 3 in your hikey960 aosp source tree, and reflash the boot img.

Btw, this hack is so bad and ugly at this point I don’t know if I’d recommend anybody using it.

What are you using this build for?

Basically trying to bring up the board with OP-TEE with AOSP and after that planning to do some hardware decoding related stuff.

@vchong,

Is there any plan to release OP-TEE with AOSP 8.X for HiKey 960 boards?
That would be very helpful for those who are trying to work on HiKey960 board with OP-TEE + AOSP.

Thanks,
Rabi

Hi @vchong,

This hack does not work for me. Getting boot time issues, board is not booting up.
Planning to integrate SDP related patches on HiKey 960 AOSP build (https://source.android.com/setup/build/devices).

Could you please suggest what are the patches need to be applied and where. That would be very helpful for me.

Thanks,
Rabi

Hi @vchong,

From where I can download
libstagefrighthw.so
libOMX_Core.so

for HiKey960 board.

Thanks,
Rabi

Hi Rabindranath,

Thank you for sharing your solution. I am also very interested to have op-tee with aosp running on hikey 960.

What does it mean in practice, TAs won’t work at all or only some features?

I was able to run test cases except the SDP related 3 test cases. SDP is not properly integrated with this customized build. In order to run SDP related test cases, need to integrate SDP patches properly which I am not aware of.

Hi @vchong

I am trying to integrate the SDP patches for Hikey960 by manually applying all the patches mentioned in https://android-review.linaro.org/#/c/17907/1/hikey-optee-4.9.

The build that I am using is Kernel build from Android source.

But the main issue that I am facing is after reverting commit 5634cf8762d848b673a0de5259264fb5681d5d00 (https://android-review.linaro.org/#/c/18281/).

I am getting a build error.

drivers/gpu/drm/hisilicon/kirin960/kirin_fbdev.c: In function ‘kirin_alloc_fb_buffer’:
drivers/gpu/drm/hisilicon/kirin960/kirin_fbdev.c:97:2: error: implicit declaration of function ‘ion_map_iommu’ [-Werror=implicit-function-declaration]

_ table = ion_sg_table(fbdev->ion_client, fbdev->ion_handle);_

This is quite obvious as the revert mentioned compromised the functions from ion.c and ion.h.

Do you have any idea how to proceed with the SDP feature?

Hello Rabindranath,

What did you do to achieve this? Did you add the selinux policies as suggested by vchong?

Should I also flash the vendor.img and userdata.img images?

Thanks

Yes need to modify selinux policies.

Yes

Hi,

I want to build Android with OpTEE but I have some issues when I run xtest.

Environment configuration

For UEFI I use UEFI Hikey960 Debug #76 binairies.

For Android environment I use this (Update 08/19) known good manifest.

For hikey-kernel -> 02ba176613f0fca9599f0c481b65edf23138d2bf

optee_os --> e07aecdb99a2f7b57ded29373c3ed23e7af5dc4b

To integrate optee in apply this patch : https://android-review.linaro.org/#/c/17833/

xtest issues

With this configuration I’m able to boot with android + optee (even if I can use mouse or keyboard for an unknown reason).

By default tee-supplicant wasn’t started, I don’t know if it’s a normal behaviour. So I started it. To counterbalance sepolicy patches which I didn’t applied I run the following command : setenforce 0.

Command: xtest

Result
hikey960:/vendor/bin # ./xtest

I don’t know why I have this issues maybe one of my components (UEFI, Kernel, AOSP + OPTEE) is wrong. Someone can say if I missed something to do ?

Thanks in advance
