CONFIG_USERSPACE on its own will not do much.

Hi Andrew,

 

I tried only with that config option…did not launch a thread with K_USER perms. Maybe I will try that.

 

Many Regards,

I'm not sure if anyone before you has tried this. We do have system calls for the socket APIs.

 

Ø  I tested out with CONFIG_USERSPACE=y

 

Did you do only this, or did you make API calls from a thread created with K_USER?

Can the current mqtt_sock implementation run in user mode thread? Are there obvious limitations that prevent it from running it in user mode?

When I tested, i didnt find any limitation . I tested out with CONFIG_USERSPACE=y
