Hi Michael,

I’m setting up an IOC, BASE-3.15.7 and autosave 5-10-1, on an Motorola board MVME-2100 using RTEMS-4.10.2.
The comand save_restoreSet_NFSHost fails on it with mount failed: Invalid argument . But my IOC is using nfs to mount it’s “st.cmd” file, so I don’t know why it is not seeing the autosave folder, that is also exported via NFS.

I remember seeing something like this problem when we switched from RTEMS 4.9.2 to 4.10.2. You are successfully mounting the /soft partition:

***** RTEMS Version: rtems-4.10.2(PowerPC/Generic (classic FPU)/mvme2100) *****
Startup.
...
***** Initializing NFS *****
Mount 192.168.99.1:/soft on /soft

I think our fix might have been that we needed to build an appropriate rtems_config.c file into the IOC (copy the version from base/src/libCom/RTEMS and edit it as necessary), but I don’t really know what the settings are in that file or if/how they might affect your application.

The base-3.15/src/libCom/RTEMS/rtems_init.c file registers the nfsMount command with iocsh, and that expects 3 arguments:

rtems_init.c:static const iocshArg nfsMountArg0 = { "[uid.gid@]host",iocshArgString};
rtems_init.c:static const iocshArg nfsMountArg1 = { "server path",iocshArgString};
rtems_init.c:static const iocshArg nfsMountArg2 = { "mount point",iocshArgString};

As Mark asked, can you use that command by hand to mount the /autosave partition?
