Hi Jithesh

currently nxp linux bsps support only A35 as master (linux side), though seems in theory

it is possible to use A35 as slave. Also from rpmsg documentation on below link it is possible

to initiate transfer from slave side too:

Hi Igor,

Thanks for the quick update .

Regarding Name Service Announce message, currently nxp linux bsps support NS Announcement handling by default? . In my understanding linux side is supporting only dynamic channel creation through NS Announcements from remote core. Is my understanding correct ?

Is it possible to initiate NS Announcement from Slave M4 . Linux bsp accepts the Announcement from slave even if it act as RPMsg master.

Could you please confirm.

Thanks
