The problem is that I can't on Microblaze little-endian platform mount nfs without -o nolock options. (Log below) Selecting tcp or udp has no effect. I am using emaclite driver and there is no problem on big endian microblaze. ping, telnet, http, ftp, iperf, netperf work well. That's why I have a question if there is any endian specific option for NFS? Thanks, Michal ~ # mount -t nfs 192.168.0.101:/tftpboot/nfs /mnt svc: failed to register lockdv1 RPC service (errno 13). lockd_up: makesock failed, error=-13 svc: failed to register lockdv1 RPC service (errno 13). ~ # mount -t nfs -o nolock 192.168.0.101:/tftpboot/nfs /mnt ~ # mount rootfs on / type rootfs (rw) proc on /proc type proc (rw,relatime) none on /var type ramfs (rw,relatime) none on /sys type sysfs (rw,relatime) none on /etc/config type ramfs (rw,relatime) none on /dev/pts type devpts (rw,relatime,mode=600) 192.168.0.101:/tftpboot/nfs on /mnt type nfs (rw,relatime,vers=3,rsize=32768,wsize=32768,namlen=255,hard,nolock,proto=udp,port=65535,timeo=7,retrans=3,sec=sys,local_lock=all,addr=192.168.0.101) ~ # ~ # ps PID USER TIME COMMAND 1 root 0:02 init 2 root 0:00 [kthreadd] 3 root 0:00 [ksoftirqd/0] 4 root 0:00 [kworker/0:0] 5 root 0:00 [kworker/u:0] 6 root 0:00 [khelper] 7 root 0:00 [sync_supers] 8 root 0:00 [bdi-default] 9 root 0:00 [kblockd] 10 root 0:00 [rpciod] 11 root 0:00 [kworker/0:1] 12 root 0:00 [kswapd0] 13 root 0:00 [fsnotify_mark] 14 root 0:00 [aio] 15 root 0:00 [nfsiod] 16 root 0:00 [kworker/u:1] 58 root 0:00 udhcpc -R -n -p /var/run/udhcpc.eth0.pid -i eth0 62 1 0:00 /bin/portmap 64 root 0:00 /bin/inetd /etc/inetd.conf 65 root 0:01 -sh 66 root 0:00 /bin/syslogd -n 67 root 0:00 /bin/flatfsd 68 root 0:00 [kworker/0:2] 91 root 0:00 ps ~ # cat /proc/cpuinfo CPU-Family: MicroBlaze FPGA-Arch: spartan6 CPU-Ver: 8.00.a, little endian CPU-MHz: 50.00 BogoMips: 24.06 HW: Shift: yes MSR: yes PCMP: yes DIV: yes MMU: 3 MUL: v2 FPU: no Exc: op0x0 unal ill iopb dopb zero Icache: 16kB line length: 32B Dcache: 16kB line length: 16B write-through HW-Debug: yes PVR-USR1: 00 PVR-USR2: 00000000 Page size: 4096 ~ # -- Michal Simek, Ing.
