I can only assume the fault is within the new uboot but I have never tested the provided rootfs+kernel in a working scenario either.
I took the opportunity to upgrade the internal drive from bookworm to trixie with kernel 6.12. But I sure wish I wouldn't have to worry about the next kernel breaking WD's uboot limits again.

There are several observation to be made here:
- Network still doesn't work, but it also doesn't crash the box anymore. I'll get back to that.
- USB seems to work fine.
- SATA works BUT only if the box has been initialized with stock uboot first then soft rebooted to kwbooted uboot. On cold boot, kwbooted new uboot can't initialize SATA drive. Basically it doesn't spin up so it returns an error.
- back to the network. Since SATA kinda works, I decided to boot my working (internal SATA) debian to check if network could be initialized from the OS side. Unfortunately, the
[ 89.209179] mvpp2 f10f0000.ethernet eth0: could not attach PHY (-19)still came back to bite me. I read somewhere that extracting the .dtb from the running kernel gets you the active state as seen by the OS, not the .dtb that's been baked into the kernel. So I pulled the .dtb from the broken uboot and the one from the working stock uboot. Next is decompilling the two and see if something's obviously different in the way the ethernet port is configured. TBH, I have no idea if I'm onto something or just going on a wild goose chase.

This is a generic PHY. While the DS215j has Marvell PHY, and it is identied as such and has no problem connecting to the PHY. The DS215j is also has Ethernet problem, though.

Yes, I've added a recently published 2026 patch to this version. I might want to rebase this u-boot to the 2026.01 version.

OK. So we need to find the SATA GPIOs in the GPL source. Stock u-boot apparently brings up SATA inside the code, not initially when it's up. I'll write a test to be executed at stock u-boot prompt.

If the stock kernel is new enough then there is a DTB. But if it is 3.x, then most likely there is no DTB. Could you post the stock OS dmesg? easy to find out if I can see it. In stock OS,
dmesg ls -l /proc/device-tree/

I wasn't talking about WD's stock firmware/OS. I ran it just long enough to delete it and that was over a decade ago. I just pulled the latest GPL code from https://support-en.wd.com/app/products/product-detailweb/p/126 (still no uboot source code, of course), it seems to be running 4.14.22 and comes with .dts. Would the SATA GPIO pins your looking for be any of these?
&pinctrl {
sata_sd_pins: sata-sd-pins {
marvell,pins = "mpp63", "mpp66";
marvell,function = "gpio";
};
sdio_st_pins: sdio-st-pins {
marvell,pins = "mpp44", "mpp45";
marvell,function = "gpio";
};
};
&sata {
status = "okay";
nr-ports = <2>;
pinctrl-0 = <&sata_sd_pins>;
pinctrl-names = "default";
sd-gpios = <&gpio1 31 GPIO_ACTIVE_HIGH>, <&gpio2 2 GPIO_ACTIVE_HIGH>;
};

If it is not the same as FW running on the box then I'm not sure if it's accurate. Please post the entire DTS file. And any DTSI file that it includes.
Also, with stock u-boot running, at the prompt, dump the registers:

Re: WD MyCloud Gen2 (Glacier, Armada 375) February 19, 2026 05:33AM |
So the above snippet comes from WD's armada-375-db.dts in their GPL source. Since it's explicitly written
Now, what I'm running as a daily on the internal drive is a Debian 13 with kernel 6.12. This installation runs fine on stock uboot. Rootfs and kernel don't come from your archive.
In addition I have your kernel 6.17+ Debian 12 rootfs on a USB stick for the purpose of testing the new uboot. I also cross tested that new uboot with my internal installation. That's how I can verify that the OS can't initialize the network with the new uboot and some random misconfiguration on the unproven USB (stock uboot expects a secondary FAT boot partition with initramfs and also can't boot from USB3).
Unfortunately, no change between spin down and spin up. If I remember correctly, this mvebu SATA controller doesn't do AHCI, it's only capable of IDE.
PS: I've never been happier that I soldered a serial port at the back of my nas years ago.
model = "WD My Cloud Gen2: Marvell Armada 375";at the top of the file, I would assume that's the file they use when they build their stock kernel. I'm not running that though.
Now, what I'm running as a daily on the internal drive is a Debian 13 with kernel 6.12. This installation runs fine on stock uboot. Rootfs and kernel don't come from your archive.
In addition I have your kernel 6.17+ Debian 12 rootfs on a USB stick for the purpose of testing the new uboot. I also cross tested that new uboot with my internal installation. That's how I can verify that the OS can't initialize the network with the new uboot and some random misconfiguration on the unproven USB (stock uboot expects a secondary FAT boot partition with initramfs and also can't boot from USB3).

Unfortunately, no change between spin down and spin up. If I remember correctly, this mvebu SATA controller doesn't do AHCI, it's only capable of IDE.
PS: I've never been happier that I soldered a serial port at the back of my nas years ago.

I have not seen the dmesg log for this box stock OS so we can't say for sure if they actually use this DTS to run the stock kernel on your box. It could be work-in-progress or used in a newer FW for this box.
With that said, since you see the correct model info in the DTS, then chance is good that we can use it for new u-boot and kernel.

Right! But USB 3.0 seems to work fine in new u-boot.

Yes, I forgot that for Armada 375, old stock u-boot use ide reset command. And new u-boot use sata init command. scsi command is used in the Armada 38x.
And the registers dump showed that the HDD GPIOs are the same, so the HDD spin up is hardcoded inside stock u-boot code.
Please try the "sata init" command in new u-boot.

So could you post the entire DTS file content here (with its associated included DTSI files), the new u-boot needs the correct DTB, too.

Attached here is the new u-boot build. This version implemented SATA GPIOs. So to verify that, it should be kwboot with the box from power off (cold start), not reboot.

This tarball contains 4 files
From another Linux box, connect serial console to this NAS, and use kwboot to load and run the kwb image.
Interrupt the countdown and
Note: ipaddr must conform to the local network, for example, 192.168.0.100, if your router IP address is 192.168.0.1.

Could not get PHY for mdio@c0054: addr 0 mvpp2 mvpp2-0: cannot connect to phy Using mvpp2-0 deviceWe'll try another test.
SATA test:
My bad, I did not add an important piece of code in the board file. Will make another build.

Attached here is the Feb 25 u-boot build. This version implemented SATA GPIOs. So to verify that, it should be kwboot with the box from power off (cold start), not reboot.
uboot.2026.01-tld-1.wd-glacier.bodhi.260225.tar
This tarball contains 4 files
From another Linux box, connect serial console to this NAS, and use kwboot to load and run the kwb image.

The result stays unchanged. I have a sneaking suspicion initializing sata and ethernet controllers is about figuring out what data to put in which registers and that's got to be a nightmare unless you have access to marvell's documentation.

Yes of course. That would be nice. But we'll live with what we have: GPL source and stock u-boot. Most of the time these 2 are enough to find certain info.
I guess we just need to digging in the source to find the info, and hope it's there.

"Failed to identify" means the driver recognized there is a disk attached. And it tried to query the model and capacity.
What kind of HDD (eg. model, capacity) is the one in slot 0? is it true that it's the only HDD attached?

The sata HD in slot 0 is the original internal 3.5" HDD. It's a standard 2TB WD red, same as those that could be bought separately and used with any standard SATA controller.
It's using a GPT table, has 3 partitions (swap, ext4, ext2 in that order) and the third one is the boot partition to keep stock uboot happy. Nothing wrong with the drive's health. Obviously, no hardware encryption either. Just a bog standard sata drive with bog standard linux partitions.
Physically, there's a single SATA port (SATA1 working in IDE mode), a single USB port (USB3.0) and a single 1Gb ethernet port. Now, the armada 375 can support 2xSATA, 2xUSB and 2xGb ethernet if the proper circuitry was populated so uboot might probe ports/PHY that aren't physically available.

I've looked at the GPL. Unfortunately the only thing useful I could find was what you've already found: the DTS.
SATA GPIO 63 and 65 are useful, but the property sd-gpios is not.
I'll add the SATA regulators to the DTS to see if it helps u-boot. And also revisit the stock u-boot registers dump.

Don't worry, good fun for me hacking these boxes :)
This NAS will continue to be updated if I can keep the kernel size down, regardless of whether we can get the new u-boot working.
