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.

Moreover in EC21EFAR06A05M4G_OCPU_20.002.20.002_SDK is present an trust zone example (ql-ol-sdk/ql-ol-extsdk/example/tzone)
I built it and after tried to run I got
I’m not able to got how I could use it.
Thanks a lot in advance
