This kind of issue comes often when tee-supplicant is not running on kernel side. @tprrt Can you please help me with link of images on which this issue is seen?

[tprrt]

Hello @sahilnxp,

Yes, your distro doesn't use systemd as init manager and your recipe doesn't provide sysvinit support, like the meta-arm's optee-client recipe.

Kind regards, Thomas

Can you start the tee-supplicant manually and then run xtest just to verify if this is tee-supplicant issue only ? There is some issue we had some time back wrt tee-supplicant not starting automatically, Will discuss with @thochstein for a fix with this.

Hi @tprrt, we use systemd for our meta-imx distro. As I remember, systemd dropped sysvinit support on Scarthgap, and I added the following in order to start tee-supplicant.

https://github.com/nxp-imx/meta-imx/commit/a546b67f088b0207e3b19a5307ff6b889d488379

Would you happen to know how to adapt that for sysvinit?

[tprrt]

Hello @thochstein ,

We don't use your meta-imx distro, especially images for manufacturing products.

Sysvinit is still supported as init manager in OE / Yocto.

Kind regards, Thomas
