Hi all!
I have currently been trying to understand the relationship between this components, in order to integrate a custom accelerator + board into TVM. As a reference, this is what I would like to try: * AutoTVM running on the host computer * Multiple boards connected to the same host computer running the AutoTVM schedules. Now, each of this boards only runs baremetal applications, so I understand that I should have a simple application running in each of them, using the MicroTVMRPCServer (similar to the [host driven Zephyr example](https://github.com/apache/tvm/tree/main/apps/microtvm/zephyr/template_project/src/host_driven)). Now in my host computer, I have the ProjectAPI of my specific configuration, already coded to communicate through UART with the board (also similar to the [Zephyr example](https://github.com/apache/tvm/blob/main/apps/microtvm/zephyr/template_project/microtvm_api_server.py)). What I am failing to understand is how the tvm.autotvm.RPCRunner and the rpc_tracker integrate with this. All examples I have seen use the RPCRunner to point to an already started rpc_tracker, which should have boards (or hardware) already registered in it. So the questions are: 1. Are there any examples running AutoTVM on baremetal devices using microTVM? (there is [one](https://tvm.apache.org/docs/how_to/work_with_microtvm/micro_autotune.html#sphx-glr-how-to-work-with-microtvm-micro-autotune-py) for microTVM but it uses the host as target). 2. Should I write my own runner in order to communicate with my board through the UART? Or should the RPCRunner be able to manage this?
