Can rpmsg lite work well as master and remote at the same time? #28

On my board, there are three cores. 1 APU and 2 R52s. Then APU works as a master to communicate with R52 A, also R52 A should actively send some message to R52 B. So for R52 A, it should run both rpmsg_lite_master_init and rpmsg_lite_remote_init. I want to know if the rpmsg-lite code can support the use like this? someone's share may help me a lot , tks.

Hello @zhangjk2752 you have to create two rpmsg_lite instances on the R52 A, each having own shared memory and link_id. It is not possible to use just one rpmsg_lite instance in case of R52 A that is intended to be both the master and remote.
