Thank's Joel
Adding '#define CONFIGURE_MAXIMUM_DRIVERS 15' to my system.h config file
make me one step further...
I still get a non-0 return value for mount_and_make_target_path. I
printed errno value before 'assert(err == 0)' line and it's errno=22
(EINVAL: invalid args); but can't tell which API function returned this
errno.
Still puzzled !

Hi
I'm trying to mount a NFS partition from a server on a sparc board.
My app is basically configuring the network, and trying to mount
the NFS server share using mount_andmmake_target_path() API.
err = mount_and_make_target_path(
"6331.1150 at 10.160.7.217:/home/marcosjl/",
"/nfs",
RTEMS_FILESYSTEM_TYPE_NFS,
RTEMS_FILESYSTEM_READ_WRITE,
NULL);
assert(err == 0);
It fails miserably :
Network initialization OK.

Registering NFS driver failed -
When digging in ./cpukit/libfs/src/nfsclient/src/nfs.c, It seems
that call to 'rtems_io_register_driver' is not successful,
probably related to misconfiguration of my app ?
This is the excerpt of my system.h file (the one containing the
configuration directives to RTEMS) :
/* Specific configuration for NFS */
#define CONFIGURE_FILESYSTEM_NFS
#define CONFIGURE_MAXIMUM_MESSAGE_QUEUES 20
#define CONFIGURE_MAXIMUM_SEMAPHORES 15
#define CONFIGURE_NUMBER_OF_DRIVERS 5
I don't think this is the right configuration parameter. It should be
CONFIGURE_MAXIMUM_DRIVERS. I don't know if 5 is the right number but
you need 1+ driver slots empty beyond the static drivers configured to
account for the dynamically installed one.
https://git.rtems.org/rtems/tree/cpukit/sapi/include/confdefs.h?h=4.10#n856
should be the section of code you are tripping.
That should get you beyond this error.
Not sure of what's going on here (I'm pretty new to RTEMS !). Is
it the correct way to configure resources expected by NFS client ?
(as per what's specified in ./cpukit/libfs/src/nfsclient/README -
section "RTEMS Resources Used Byy NFS/RPCIOD")
Thank's in advance...
