I've created /etc/network/interfaces file with sample content:

...but if network device isn't available I can't bring it up.

so it seems our problem is failing loading of firmware that this module need

That is right but there is class_c2000.elf inside /lib/firmware :scratch

[fvdw]

the files needed are in /lib/firmware
The reason of failure could be that the files there do not have executable permission
So do this

Code: Select all

chmod 755 /lib/firmware/*

Check that the files have now executable permission
Then boot again the wd cloud

ps there is also an " missing in /etc/init.d/rcS line 57

Code: Select all

echo "add ip 192.168.1.200

this should be

Code: Select all

echo "add ip 192.168.1.200"

[fvdw]

I edited my last post

....missing in /etc/init.d/rcS line 57..

[matt_max]

Still no luck with loading firmware - console output.

Code: Select all

~ # ls -ll /lib/firmware/

I found that

There are some words about firmware in Documentation/firmware_class (and this works in debian!) but also there is "Userspace firmware loading is deprecated, will go away, and sometimes causes problems" in
/usr/share/doc/systemd/README.

and late

In Fedora systemd is compiled without userspace firmware loading support, and requires at least kernel 3.7 to function properly. If you're using kernel 3.2 then things will break. You can recompile systemd (up to version 216)
with --with-firmware-path=... but this not supported by the distribution.

Someone tried to run Fedora on WD MyCloud.

[fvdw]

I am going to look into wd firmware to see how they load the module

[fvdw]

seems this script /etc/init.d/kmod loads the modules using a file /etc/modules
this is the line we see as output in wd firmware when loading modules
Look to this part of kmod script

Code: Select all

.....
load_module() {
  local module args
  module="$1"
  args="$2"

  if [ "$VERBOSE" != no ]; then
    log_action_msg "Loading kernel module $module"
    modprobe $module $args || true
  else
    modprobe $module $args > /dev/null 2>&1 || true
  fi
}
..

the /etc/modules file contains this

Code: Select all

# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.
# Parameters can be specified after the module name.
pfe lro_mode=1 tx_qos=1 alloc_on_init=1 disable_wifi_offload=1

So our modprobe line in rcS script should be

Code: Select all

modprobe pfe lro_mode=1 tx_qos=1 alloc_on_init=1 disable_wifi_offload=1

Try to modify the modprobe line like that

[fvdw]

when that does not work we we have to look into this possibility

Firmware loader for the Gen1 WD MyCloud network interface when there is no udev available
(https://gist.github.com/marcsello/3622b ... -loader-sh)

Code: Select all

So our modprobe line in rcS script should be

modprobe pfe lro_mode=1 tx_qos=1 alloc_on_init=1 disable_wifi_offload=1

Try to modify the modprobe line like that

First I remove module with rmmod pfe to be sure it is not loaded:

Code: Select all

Then I try to load module with parameters:

Code: Select all

~ # modprobe pfe lro_mode=1 tx_qos=1 alloc_on_init=1 disable_wifi_offload=1
