Hi, I am trying to setup a scenario where the parent starts a child PD in the C code, i.e., there is no <start> node for the child in the config file. It is similar to the rm_nested test example [1].
But in my scenario, I would like to start a server in the child and have the parent make RPC calls to it, and I need some help setting that up. I think the answer should be in some configuration of the ChildPolicy used to start the child, but I am missing something.
My code is here [2,3] and is a hybrid of the hello_tutorial and the rm_nested test case. Like rm_nested, the parent starts a child with the same binary and uses the failure to reach the RM service to indicate that it is in the child. But then, in my scenario, I start a HelloServer in the child, and the parent tries to establish a connection to this service.
I am seeing two errors: 1. An error that Genode complains that it wasn't expecting the child to announce a service. I tried fixing that by defining announce_service() in the Test_Child before starting the child, but that didn't fix it. TBH, I am wondering what to add to that function. 2. The parent cannot find the "Hello" service to connect to. I think that fixing (1) would fix two as well.
Any help pointing me in the right direction would be very helpful. Thanks as always!
