OPTEE 2.0 tee-supplicant issue

Shengye Wan

Hi experts,

Today I was trying to use the latest OPTEE version to replace my previous one (v1.1.0) on my Juno board and I met one issue about tee-supplicant.

I used the initialization script from ashwildingarm 's post with the choice "Juno, latest, openembedded".

Now I have booted up my board with the new system.
I could successfully run the command modprobe optee_armtz while I got the error -sh: tee-supplicant: command not found when I was trying to use the command tee-supplicant &.

Is there anything I missed for running tee-supplicant?

By the way, now I'm following the instruction of optee_test for running TA.
If you have any other document about running a TA / xtest on latest OPTEE, please let me know so I could check the document by myself.

Thank you.

    Hi Ash,

    Thank you for the reply.

    I just tried the script with the choices: build-from-source, Juno, lsk-4.4-armlt, OpenEmbedded LAMP.

    I build the OS and make the hello_world program successfully.

    For your notes,

    # mkdir -p /lib/teetz/    <-- Note: I *think* this is actually supposed to be /lib/optee_armtz/ but my notes are outdated

     

    # mv *.ta /lib/teetz/     <-- Same as above, I think you need to change this to /lib/optee_armtz/

    Yes, the TA part should be saved in the folder optee_armtz instead of teetz now.

        # insmod optee.ko         <-- You may not actually need to insmod this

     

        # insmod optee_armtz.ko   <-- Same as above, you may not actually need to insmod this

    I didn't find any file with name "*.ko" under my workspace. I also checked the folder which contains the source code of optee.ko and optee_armtz.ko while I got no ".ko" file there after building.

    In this case, I didn't insmod anything on my board.

    However, I could execute the command tee-supplicant & so I assume these steps are not necessary.

    Now, when I running the client application, I got the error

    ERR [2098] TEEC:TEEC_InvokeCommand:567: TEE_IOC_INVOKE failed

    hello_world: TEEC_InvokeCommand failed with code 0xffff0000 origin 0x2

    after the program outputs

    Invoking TA to increment 42

    correctly.

    For the secure OS side, I got the debug information as follows:

    DEBUG:   [0x0] TEE-CORE:tee_ta_init_static_ta_session:160:    Lookup for Static TA 8aaaf200-2450-11e4-abe20002a5d5c51b

    DEBUG:   [0x0] TEE-CORE:tee_ta_close_session:318: tee_ta_close_session(0xff05bf20)                                     

    DEBUG:   [0x0] TEE-CORE:tee_ta_close_session:337:    ... Destroy session                                               

    DEBUG:   [0x0] TEE-CORE:tee_ta_close_session:358:    ... Destroy TA ctx

    I'm not sure this error is caused by missing "*.ko" files or something else.

    Could you please check this and see if you have any idea about what might be wrong?

    Thank you very much.
