Since there isn't an RFC, I'll drop this comment here, what does a somewhat
working example look like?
Updating the micro tvm tutorial as inspiration :
target = "c --system-lib --runtime=c"
input_tensor = "dense_4_input"
input_shape = (1,)
input_dtype = "float32"
dev_config = micro.device.arm.stm32f746xx.generate_config("127.0.0.1", 6666)
mod, params = relay.frontend.from_tflite(tflite_model,
shape_dict={input_tensor:
input_shape},
dtype_dict={input_tensor:
input_dtype})
with micro.Session(dev_config) as sess:
ctx = tvm.micro_dev(0)
with tvm.transform.PassContext(disabled_pass={'FuseOps'},
config={"tir.disable_vectorize": True}):
graph, c_mod, params = relay.build(mod, target=target, params=params)
micro_mod = micro.create_micro_mod(c_mod, dev_config)
mod = graph_runtime.create(graph, micro_mod, ctx)
mod.set_input(**params)
mod.set_input(input_tensor, tvm.nd.array(np.array([0.5],
dtype="float32")))
mod.run()
# Get output
tvm_output = mod.get_output(0).asnumpy()
print("result is: "+str(tvm_output))
This feels like it should be close however it fails at
micro.create_micro_mod

Should that be expected for the time being?
