EC21 Trust Zone - CONFIG_QTZONE

Hello,
I’m looking for any information about Trust Zone in Quectel EC21.

I’m running EC21EFAR06A05M4G_OCPU_20.002.20.002 version, and typing “make kernel_menuconfig” I found “CONFIG_QTZONE” kernel configuration.
Once enabled it, built everything and flashed, I was able to found a new device in /dev (/dev/tzone).

Now, I’d like to run ql-ol-sdk_new/ql-ol-extsdk/example/openssl/crypto-tz example but in my rootfs /usr/lib/libql_openssl_tz.so.1 is missing.

Could you help me?

Thanks in advance

Hi @sbong

Sorry,there are no relevant documents to share, because it has not been maintained for too long.
If you must use QTEE, I suggest upgrading the baseline, at least using the tz4.0 baseline.
Could you get the saler or FAE supporter

Hello @Puck-Q,
thanks for the reply.
You mean that EC21EFAR06A05M4G_OCPU_20.002.20.002 is not the latest?
What is the tz4.0 baseline?

Thanks a lot in advance.
