For what it is worth, I turn on NNCASE_DEBUG https://github.com/kendryte/kendryte-standalone-sdk/blob/28ff67adf27f06a92cd4f1b81ab9aa5d0bb93740/lib/nncase/nncase.cpp#L25 it will output layer timing statistics. It might be enough. For example ```KPUConv2D: 0.084000ms KPUConv2D: 0.485000ms KPUConv2D: 0.083000ms KPUConv2D: 1.441000ms...

I saw something similar. Try increasing the timeout. `-t 0.01` To `-t 1`
