Nfs: server 192.168.37.200 not responding, still trying Solution

Nfs: server 192.168.37.200 not responding, still trying solution problem: 1. You want to use NFS to load the root file system to the target board to debug the root file system. However, after the NFS service is configured on the host, you can see the content in the root-pdu-422 through # sudo mount-t nfs localhost:/nfsroot/root-pdu-422/mnt # ls/mnt, it indicates that the nfs server has been set. 2. The previous system successfully mounted the root file system through nfs. The current system is reinstalled. I tried many methods to modify the bootargs of the target board u-boot, but the problem persists. Solution: 1. after a dog is searched, it is not a problem. Basically, there are many network problems. 2. because the current network is added with a vro192.168.192.168.37.1 under the vro1.1 192.168.1.1, it is suspected that it is a problem with the vro; change the target board to the 1 network segment and restart the target board, the target board is mounted to the root file system through nfs. The problem is solved.
