Hey guys,

Just a small guess, maybe you can try booting my initrd via tftp https://themm.net/public/ex2u/start
With the smaller Ex2u this will drop you into a small busybox, and there is everythink working, even without powerreg.
With a standard uInitrd I did'nt got it running.

Cheers

Unfortunately with usb 3.0 stick it is not working at all. :(

Ah! sorry that's exactly should happen. Thanks for trying saschadd!

When I have a couple hours free, I'll find the GPIO and we should be able to use USB drive.

Hey bodhi,

grepped through the WD kernel source and u-boot source, and couldn't find PWREN_USB_REG_OFFSET anywhere. Is it possible it's under a different name?

Yup, this boots to busybox for me. Nice!

I will need to compile this kernel with a new DTS to enable the second Gigabit interface on the EX2100...

Yes, it was a wild guess :) it could be any thing WD decided to use. I think we need to search for "yellowstone" or "yosemite" like you've found, and then read that code.

Just as a note to anyone else working with the EX2100 who doesn't want to open up the case and void their warranty (*cough*). You can get a functional uart connection without *any* soldering! Just requires kapton tape, alligator clips, and a lot of patience. On the edge connector with 3 contacts, cover the two outer contacts with kapton tape. These are (from left) 3.3v, Tx, and GND. Since the alligator clips are quite fat, we want to avoid shorting Tx to 3.3V or GND.

The edge connector with 1 contact doesn't seem to be connected to anything, or at least I couldn't determine that the lone contact did anything whatsoever. So I had to attach to pin 5 to get uart Rx, which is thankfully quite close to the edge of the board.

For ground, just attach an alligator clip to the metal at the top of the SATA slot.

Janky, but it works! See the photo if this all sounds too confusing.

Sound's good! But just to make sure: you booted the debian installer not he custom initrd; With the initrd debian should be booting as well.

Hehe, got another ugly uart installment which works ; )

I just destroyed an old isdn socket to use the pins for clipping and soldered an old cd connection cable to that to put it on my raspi. ugly but works. ;)

Meanwhile i put the cable through a hole on the first row of the air flow holes and can even close the box while still having my uart connection. so now it is less ugly and still works.

happy hacking,

Yes, I realized this once I got into it. However if you go back enough with the Debian installer, it will eventually allow you to drop to a shell.

Why are vendor GPL archives always crap?!

:)) They are crap because they paid cheap wages to people who modified SoC manufactor GPL code to make it work.

Marvell GPLs are decent (old code, old SW design but quite good). It's vendors like Xyzel and WD that made it worse.

Courtesy of the WD u-boot source code, I have figured out what Yosemite and Yellowstone are referring to:
http://www.businesswire.com/news/home/20061030005307/en/AMCCs-Expanded-Family-PowerPC-Evaluation-Kits-Accelerates

Why are these seemingly the code name for Western Digital's products? Who knows! Yosemite and Yellowstone are for a completely different CPU architecture (PPC) from a different manufacturer (AMCC).

Why are vendor GPL archives always crap?!

Edit: found in the toolchain archive:
export PROJECT_NAME=WDMyCloudEX2100
export CODE_NAME=Yosemite

OK. So we need to search for other terms. I have donwloaded WDMyCloud_EX4100_GPL_v2.30.165_20170321.tar.gz.

I did some comparison between the WD u-boot source and the mainline u-boot source. Perhaps I am too simplistic, but it seems like you could add saveenv by editing include/config/armada_38x.h to add:
#define CONFIG_CMD_SAVEENV

Since it seems not possible to uart boot u-boot, I haven't tested this yet. However, the resulting u-boot image is larger than if you build it without the above define statement:

Without CONFIG_CMD_SAVEENV:
New image size = 0xd7780[882560] Source image size = 0xd777c[882556]
====>>>> u-boot-a38x-Yosemite_2014T3_PQ-nand.bin was created

With CONFIG_CMD_SAVEENV:
New image size = 0xd7bac[883628] Source image size = 0xd7ba8[883624]
====>>>> u-boot-a38x-Yosemite_2014T3_PQ-nand.bin was created

Is there any way we can safely test to see if the new u-boot image contains saveenv?

hmartin,

It's really easy to activate saveenv. But we'll need to flash new stock u-boot. So it is not recommended without being able to kwboot it first.

Once we can kwboot the box, then I'll develop a new u-boot for it. It is practically the same as for the Xyzel NAS326.

With that said, I will hopefully figure out a way, but I'd prefer to work on that only after we booted Debian on USB. It is too early to think about saving envs.

Sorry if I'm being really dense, but haven't we already done that? Peacemaker's kernel and initrd works. I can load it and boot to Debian all on a USB 2.0 stick plugged into the rear USB 3.0 port on my EX2100.

So, apart from some DTB cleanup (e.g. Peacemaker's kernel only initializes one of two Ethernet interfaces, and rebooting doesn't work properly) isn't all that's left to flash u-boot with saveenv and then you can boot Debian entirely from USB?

I'm not sure what's wrong with your initrd that keeps kernel panic'ing, but Peacemaker's boots.

OK :) you should have posted this log. I was under the impression that you and saschadd could not do this. So the USB power activation by u-boot was enough to let the kernel mounting the rootfs.

So the remaining issue is just the size of the Initrd or something in the older kernel perhaps. Because it booted fine on the NAS326, it is most likely the size.

Sorry, before I only tried booting it with tftp, but since your feedback I wondered why not try booting from USB since that is the major issue we face?

I'm not sure which filesystems this u-boot supports, so I formatted the USB stick as ext2 just to be conservative. I am using your mvebu rootfs with the uImage and uInitrd from Peacemaker's page.

One thing that concerns me slightly is that there is no source available for this uInitrd. It's only been published in binary form. If we want to actually distribute this, we should ask cschil for the source so we can build it.

I'll post a different way to boot my kernel files so you guys can try.

The small uInitrd from peacemaker is great for testing it out, but we (this forum) need a Debian style uInitrd which has all the modules so we can run all MVEBU Armada boxes using the same kernel.

I understand. But the initrd only needs to contain the modules necessary to boot. The remainder of the modules (e.g. to support things like NFS, iSCSI, USB cameras, etc) can live on the rootfs, since they're only needed after booting.

I took a quick look at the uInitrd you're shipping in the rootfs, and there are quite a few modules I would say could be relocated to /lib/modules on the rootfs, and not living in the uInitrd.

Examples:
./drivers/hid
./drivers/hid/hid-penmount.ko
./drivers/hid/hid-roccat-isku.ko
./drivers/hid/hid-roccat-lua.ko

I totally understand if you say you don't want to remove these modules from uInitrd, because there is some edge case where they would be needed on boot. But if the issue is that the Debian uInitrd is too large to boot successfully, then removing unnecessary modules from uInitrd is an easy way to reduce the size.

I am happy to test whatever you come up with :-D

That's too much of a hack! a good hack to make it work :) but it will become a maintenance issue.

The issue at hand is not the size of uInitrd itself. It is a buggy and old stock u-boot. Once we have a new u-boot for this and the NAS326 box, this issue will resolve itself magically. For now, we are just working around this limitation by exploring different boot options.
