OPTEE 2.0 tee-supplicant issue

Hi Simon,

It's been a while since Iast did this so some of this may be outdated, but please find my notes below for running the OP-TEE Hello World example TA found in this GitHub repository, hopefully this will help you identify any steps you may be missing for running your own TA (note how we build tee-supplicant and copy it to the board, then run it).

1) Use the workspace script to sync a new build-from-source Juno lsk-4.4-armlt + OpenEmbedded LAMP workspace

1) Boot the Juno to the OpenEmbedded LAMP terminal prompt and get its IP address using ifconfig

2) Execute the following commands on your host Linux computer:

    $ export HOST_CROSS_COMPILE=<workspace>/tools/gcc/gcc-linaro-4.9-2015.05-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-

    $ export TA_CROSS_COMPILE=<workspace>/tools/gcc/gcc-linaro-4.9-2015.05-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf-

    $ export TEEC_EXPORT=<workspace>/optee/optee_client/out/export

    $ export TA_DEV_KIT_DIR=<workspace>/optee/optee_os/out/arm-plat-vexpress/export-ta_arm32

    $ cd <workspace>/optee

    $ git clone https://github.com/jenswi-linaro/lcu14_optee_hello_world

    $ cd lcu14_optee_hello_world/

    $ make

    $ scp host/hello_world root@<juno_ip_address>:~

    $ find -name "*.ta" -exec scp {} root@<juno_ip_address>:~ \;

    $ cd <workspace>/optee/optee_client/out

    $ tar zcf export.tar.gz export/

    $ scp export.tar.gz root@<juno_ip_address>:~

    $ cd <workspace>/optee/optee_linuxdriver/

    $ find -name "*.ko" -exec scp {} root@<juno_ip_address>:~ \;

3) Execute the following commands from your Juno OpenEmbedded LAMP terminal prompt:

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-- Note: I *think* this is actually supposed to be /lib/optee_armtz/ but my notes are outdated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

    # 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

    # tar xzf export.tar.gz

    # export LD_LIBRARY_PATH=~/export/lib:$LD_LIBRARY_PATH

    # ./export/bin/tee-supplicant &

    # ./hello_world

And you should see this printed:

    Invoking TA to increment 42

    TA incremented value to 43

Which shows that the Trusted Application (TA) is working.

Hope that helps!
