Hello,

Two days ago, i re-install optee from scratch. I'm using fvp i can execute xtest for instance. When i downloaded comcast crypto demo, i can't build it. It says "Not Supported" can you please explain me where is the problem ?

I removed the cases you test, it seems to work but no ta is generated.

Thanks.

Hello,

When I compile and run this example on QEMU using the build instructions I get the following error:

comcast_crypto_demo: TEEC_InitializeContext failed with code 0xffff0008

I have looked at the GlobalPlatform client API and according the error table it says that errors 0x00000000 to 0xFFFEFFFF are implementation specific errors. See page 25.

I am trying to run this example on the QEMU build from the dev repo manifest. I also have tried the Hello World example and it gives me the same error.

Any ideas?

Hi,
I wondered if there is a way to debug a trusted application which is running on top OP-TEE/LINUX, where qemu is the emulator used.

Thank you very much!

Hi,
I has run the setup_fvp_optee.sh successful, but when I make this TA, some error has happened. It shows this
"arm-linux-gnueabihf-ld: error: out-client-aarch64/636f6d63-6173-7420-63727970746 f2074.elf uses VFP register arguments, /home/opensuse/fvp-tee/optee_os/out-os-fv p/export-user_ta/lib/libutee.a(ta_trace.o) does not"
It seems the TA need to be build with soft float.
Best Regard,

When I run TARGET=fvp ./build_comcast_cryptoapi_ta_example

I got the error
