Looking for a Post about Linaro and Juno from Old Website

Hi experts,

I once bookmarked a weblink https://community.arm.com/docs/DOC-10804 which is showing how to set up a workspace for Juno board with OP-TEE 16.02.

Now I want to find a way to set up a new workspace with OP-TEE 16.02 while the URL is automatically redirected to the new website Using Linaro .. . In the new webpage, all of the set-up work has been done with a script.

I tried to use the new script with OP-TEE 16.12 while there is an OP-TEE issue when I was actually running my issue.

Since ARM doesn't officially support Linaro products and I couldn't solve my bug, I have to stay with the OP-TEE 16.02.

My question is: Is there any way for me to find the old instructions from https://community.arm.com/docs/DOC-10804 so I can set up my workspace again?

Thank you very much.

Hi Ash,

Thank you for updating the FAQ.

I just tried it again while I still got error in the last step.

Here is my terminal information from normal world:

root@genericarmv8:~# ./export/bin/tee-supplicant &
[1] 365
root@genericarmv8:~# ./hello_world 
Invoking TA to increment 42
ERR [366] TEEC:TEEC_InvokeCommand:567: TEE_IOC_INVOKE failed
hello_world: TEEC_InvokeCommand failed with code 0xffff0000 origin 0x2

I think I execute the tee-supplicant successfully while I have no idea the TEEC_InvokeCommand was failed.

Also here is my output from secure world:

DEBUG:   [0x0] TEE-CORE:tee_ta_init_static_ta_session:160:    Lookup for Static TA 8aaaf200-2450-11e4-abe20002a5b

Looks like I load the dynamic TA while it met some error. Have you met this before?
