[zifeng-radxa]

I am using RKNN_v1.6.0, and my system have been success install RKNPU2, but when i try to use rknn_server to use PC inference, I got can not start rknn_server

I have been checked my process without rknn_server, and i start rknn_server by command ./usr/bin/rknn_server
the output be like

rock@rock-5a:/usr/bin$ rknn_server 
start rknn server, version:1.6.0 (535b468 build@2023-12-11T17:05:07)
I NPUTransfer: Starting NPU Transfer Server, Transfer version 2.1.0 (b5861e7@2020-11-23T11:50:51)

without end

but I use ps | grep rknn_server, can not find eknn_server

It seem unnormal
