RE: EPICS IOC NFS mount and TFTP issue for the mvme3100 board, please help, urgent !!!

["Zhu, Lixin" <Zhu@frib.msu.edu>]

Thanks for your quick reponse,

In fact,    I only configured the 2 env varibale,  

 1) mot-script-boot 

 2) epics-script 

MVME3100> gevShow
mot-script-boot
tftpGet -c192.168.10.9 -s192.168.10.10 -fdemo/test.boot
netShut
go

epics-script=192.168.10.10:tftpboot/demo:st.cmd
Total Number of GE Variables =2, Bytes Utilized =132, Bytes Free =3460
MVME3100> 


Before the RTEMS taking control, the networking is fine. If not, the Motload can't download the test.boot into the memory, and the code runs smoothly.


I don't know how to check the networking is working or not, as the test.boot ( IOC demo)  running and taking control of the whole system , and entering the IOC shell.


I think maybe the
                              1)  the target board and nfs server  channel broken 

                             2)     nfs server or tftp server side, need some specifial conifurations. It seems the RPCIOD ( nfs ) can't send data to the server side.

What is your RTEMS network configuration (the 'SEND failure' and 'Can't
send...'
messages indicate that networking is not configured correctly or at all)?
Did you follow the instructions:
