Note: The following methods are reprinted. I have adopted a combination of methods.
Mount-T nfs-O intr, nolock, rsize = 4096, wsize = 4096-o tcp 192.168.1.3:/root/somedir/Host
NFS: server is not responding, still trying SolutionMethod 1:
The following error message is displayed when I share files through NFS on the arm.
NFS: server is not responding, still trying
Cause analysis: the default NFS transmission protocol is UDP, and serious Nic packet loss occurs when the PC interacts with the embedded system through UPD.
Solution: switch to the TCP protocol on the client and use the following command,
# Mount-o tcp 10.10.19.25:/home/export/mnt/local
Method 2:
Problems encountered when copying large files on the PC to the target board through NFS on the target board:
NFS: Server *** not responding, still trying
Modification method:
NFS crashes during NFS mount. Mount the NFS as follows:
Mount-T nfs-O intr, nolock, rsize = 1024, wsize = 1024 192.168.1.3/root/somedir/client

essential, you have to pass some options to the kernel on terminal
boot, and this varies depending on whether you are using etherboot or
PXE.

for a deeper explanation of the problem and the cure.
// Note: The reason is that the transmission rate of the NIC of the server and the target machine conflicts, so that the target machine needs to copy a large number of data packets in a large amount of time. In fact, if the NIC speed of the target machine is large enough, no need If there are so many packets, there will be no conflict.
Appendix 4: During the test, "./progressbar-qws" prompts the same as Q3, which should be handled by Q3.
