I would appreciate it, if you can share this script. There is not only "the lack" of trust, with this script, it's easy to keep the binarey up to date.

And by the way with the latest ethernet-patch from bodhi wol works fine with a 4.13 kernel, maybe I should update my github. :-/

Here's the script. I've only tested it on debian stretch, for debian stretch.
Not much of any error handling in it either.

As someone previously noted, you should modify initrd/bin/resume to use -e instead of -h to find "init", when you're on a linux dist that has init as a regular file instead of a symbolic link. Like stretch.

I'm trying to put a 4.14 kernel together.

I didn't get WOL working.

Can you elaborate, what you did? Which wakeup tool do you use, with which commandline? Are you setting flags with ethtool? Which patch do you use?

Thanks!

I updated my mcm-daemon repo with patches and configs for newer kernels.

I got 4.14.18 running and fixed the missing ethernet. It was due to needed changes to the dts file.

I also added bodhi's ethernet and LED patch, but WOL still doesn't work for me, the LEDs are not yet tested.

Thanks MM!

I think if hmartin can get this mcm-daemon to work on the WD My Cloud EX2100, it would be great!

MM: I was looking through the commit you did to your repo, 4f949e169b254b78ee76978e2e192525df36f330, which was the LED and WOL patch.
I'm not seeing any WOL based functionality added there, just a few debug prints. So perhaps that's why it's still not working for you?

Br

Yes, that's why I was asking which patch he used. I didn't find anything else.

The LEDs work fine by the way, thanks bodhi!

Hi MM,

The WOL did not really have any patch other than debug prints while we were trying it.

I recall that I've concluded that the network chip has WOL built in and all we need was using ethtools to activate it. So I left the the debug prints in there to see the progress. However, this has not been finalized, WOL still does not work on my NAS326 either.

Hey,
I can have a look how I get WOL working within my "old 4.13" build, this weekend.
As it is working fine, after you activated WOL with ethtools.

Cheers Carl

Sounds great! wonder if we have the same chip on your WD box and my NAS326?

Hello everyone,
this is my first post and I'm a newbie to the topic of compiling a kernel and working with the arm toolchain.
I've read almost all the topic, the how to by MM and the topic by fox_exe in wd forum about the alternative firmwares.
I actually own a WD MyCloud Mirror Gen2 and I want to update to debian to install openmediavault or anything else better than the buggy and limited WD MyCloud.
I've read also the topic into the WD forum and considered the option to update to DSM, but I feel uncomfortable about the bugs and being a black box because I'll continue to use this device for Backups.

Anyway, I'm a little paranoid, and I would like to build everything by me. Also I want the ability to update when required and I would like to encrypt the drive using the hardware acceleration.
For these reason I think I'll follow the how to from MM trying to get think working.

I'm a bit confused about the dts provided in this forum being different with the one created by fox_exe on wd forum.
Also he provides an easy wd_to_debian binary upgrade and a Stretch rootfs, that I think would fit nicely in the nand but for some reason is fitted in the drive.

To avoid the drives being always on, there isn't any way to prevent the rootfs being written in the hard drives? Cannot fit in the nand? Cannot use an external usbdrive?

There wasn't any update from March. Is this topic abandoned?

In conclusion if the nand cannot contain a minimal debian install, I would like to chain the rootfs in the hard drive to the nand. Than, from the rootfs mount the raid with the password that I'll manually input after every reboot.

Thank you very much for your hard work!

Although there is some free space in the Nand flash I do not think that it is advisable to try to put your whole Debian in flash. The few GB you lose on the disk are not worth the effort.

Someone has described in this forum how to encrypt the whole disk using luks and he stored the pwd in flash. Asking for the password at each boot is problematic because at this stage you have no ssh available. Most probably it would be easy to put the password on an USB stick.

@ CyberPK,

I do agree with LinAdmin about not to put Debian on NAND flash.

However, to me it is more important that when you run your Linux distribution on NAND, it tends to be unsecure. IOW, you will not update your system to get security patches as often as when it is on USB or SATA.

Thank you for answering.
As you have understood I'm not an expert.

Do you think is a good idea to run debian from an usb drive? This way I'll avoid the drive spinning all the time?
What about the differences in the dts file by this forum users and the fox_exe version?

At now, I've used the fox_exe binary to convert the wd to debian Stretch and flashed his rootfs. Then I've compiled the kernel 4.14.59 and flashed but can't go over the initrd (only recovery available). I've flashed also the initrd, with the same behaviour.
Initially the problem was the label of the partition was not "rootfs" but "ROOTFS".
Now, if I launch the 'resume' command, I get an error about the /dev is in use and the exec switch_root /mnt/root /sbin/init does not produce the expected result.
Actually the drive has 3 partition in raid: swap, rootfs, data. Maybe the md1 partition cannot be used?

CyberPK,

Yes. I have several plugs that are running 24/7 with USB rootfs. Some preparation suggestions to make sure the USB drive will not be worn out by constant write access:

I can't comment on that since I did not work on this box. I think you need JanN, MM, and Peacemaker, perhaps others in this thread to chime in.

Hello,

I've compiled the kernel by my own, but I cannot boot to debian installer with ssh.
Because I'm not able to find an usb to com adapter, I'm trying to use the network-console initrd modified with the preseed.cfg.
I'm able to boot from usb drive following the instruction from https://themm.net/public/ex2u/start but if I use the network-console initrd with or without the preseed, the wd starts and after about a minute reboots and keep the light flashing red.

These are the commands that I run to generate the uRamdisk:
wget http://ftp.debian.org/debian/dists/stretch/main/installer-armhf/current/images/network-console/initrd.gz
mkdir initrd; cd initrd
gzip -d < ../initrd.gz | cpio --extract --verbose --make-directories --no-absolute-filenames
cp ../preseed.cfg ./
find . | cpio -H newc --create --verbose | gzip -9 > ../initrd_preseed.gz
cd ..
mkimage -A arm -T ramdisk -n "debian stretch installer with preseed" -c gzip -d initrd_preseed.gz uRamdisk

this is my preseed.cfg:
d-i netcfg/disable_autoconfig boolean true
d-i netcfg/get_ipaddress string 192.168.1.42
d-i netcfg/get_netmask string 255.255.255.0
d-i netcfg/get_gateway string 192.168.1.1
d-i netcfg/get_nameservers string 8.8.8.8
d-i netcfg/confirm_static boolean true

d-i anna/choose_modules string network-console
d-i network-console/password password test
d-i network-console/password-again password test

Can you help me?
Keep in mind I cannot access the serial at thi point, otherwise I had already installed debian following themm instructions.

Regards

***EDIT***
The problem was caused by the kernel I've compiled (4.14.59 following the themm wiki). Using the precompiled one the setup has started correctly via ssh

Can I use the files in this topic? https://forum.doozan.com/read.php?2,32146 (Advanced Linux Kernel 4.18.5 MVEBU package and Debian armhf rootfs)

Hi Fran,

Yes. You can use the rootfs (and kernel 4.12.4-mvebu-tld-1 in it) to start.

Debian-4.12.4-mvebu-tld-1-rootfs-bodhi.tar.bz2

The special patches and stuff that people have done this this tread will make it complete for this box (I myself do not provide supports for this box).
