RE: i3c application

Hello Boris,

Does there have open source repo in internet?

I can used?

use i3c-tools for? What should it contain? I'm not against the idea, but I'd
like to delimit the scope of the userspace >interface.


Sure, it definitely a user space application.
I will connect with some i3c device or have loop back interact. I3c master
<-> i3c slave

test?

next read request coming from the >>master returns what the master wrote in
its previous write access?

Thanks, if I can refer from with I3c-tools, I can start for i3c-master and
i3c slave dummy test.
