   Hi all,

              I am a new comer for the EPICS (10 days ), and  I am now porting the RTEMS + EPICS to mvme3100 board. I meet the following case ,



 1)      For the  NFS mode,  after i downloading a ICO simple example example.boot, it shows the following infor.

192.168.10.9> pwd
/tftpboot/demo/iocboot/ioctest
          
                 I can't mount the nfs server , the  st.cmd can't be called by the example.boot .

   The  server is Debian lenny. I used another Unbuntu linux to mount the nfs server exported directory successfully .

   Any fast method to work aroud the issue ? 



2) Since the nfs does't work, i try to turn to the TFTP mode . however,  the error as the following ,


vmeTsi148 - IRQ manager using VME CSR to flush FIFO

6 I2C devices registered

Registering /dev/console as minor 0 (==/dev/ttyS0)

           I don't know wether the st.cmd file would be downloaded from the server automatically or not.  It is really no file, only empty directory.

 Anyone who knows about this issue ?
