You can run Linux VM on your Mac, too. Usually putty on Windows or screen on Mac should work fine. But for recovery purpose (i.e. running kwboot to boot over UART, you will need Linux). So getting a low cost rPi is handy, it already provides the serial converter.

Yes, for most of the serial module converters RX-TX need to be crossed. A few (old) converters with CP2xxx chip alrady crossed.

But as always, if you don't see anything on serial, then try crossing RX-TX.

I have some Rasp, and I'm doing some tests.... but nothing works :( sometimes moving the pins in the board I get som characters, but it's strange because with a multi tester the connection between both works... honestly I don't know that else I can do.

Do I need to connect any hardrive?

Check GND wire. You should connect only 3 wires GND, TXD, and RXD.

> Do I need to connect any hardrive?

Not need.

====

You probably can find serial console info in the WD Ex2 Ultra working thread, and confirm the correct pinouts.

The connector has the following pin map:

5 o <-- RX Data
4 (No pin)
3 o — N/C (3.3V)
2 o — GND
1 o --> TX Data

Also

On the PCB inside the EX2, there is an (un)populated 5pin header on the back (side opposite the CPU). You can see the header I am talking about in the bottom image on this review: http://www.eteknix.com/western-digital-ex2-2-bay-8tb-my-cloud-nas-review/2/ 59

In my earlier post I mentioned the connection order for the pins.

Indeed this the pin map I’m following. It was really hard to solder the pins.

I’ve tried with the cross connections and direct, but it did not work. Sometimes, as I mentioned before, I can see some characters when I move the wires, but I don’t know how to double check if everything is well solder

Thanks for your help

That would be the noise on the wires when you move them.

You can check one end to make sure it is OK (on the server end, i.e. the rPI). Loop back to RX to TX on this end, and type something, it should echo back the character. If you don't see any thing, then you'd know something wrong with the console settings (baud rate, data bit,....).

On the NAS end, I don't know anyway to check the soldering. Perhaps others might have some idea.

Thanks for your advice, I’ll do it tomorrow… time to sleep in Ams :)

Done, and works fine I can type and see what I am writing

Open for any idea here :)

I'm done.

I have rechecked the solders, all has continuity in both sides, but it's clear that something is broken in my board, and I don't have enough skills to figure it out and/or fix it.

Now it would be nice if I could boot from usb, or an internal drive to try to unbrick it.

I followed the steps below and after that, the box is not booting anymore:

## Usage 
# Update Kernel if you have access to shell
wget https://raw.githubusercontent.com/vzhilov/WDMC-Ex2-Ultra/master/uImage (--no-check-certificate in case of error?)
dd if=/dev/zero of=/dev/mtdblock1
dd if=uImage of=/dev/mtdblock1

# Update ramdisk if you have access to shell
wget https://raw.githubusercontent.com/vzhilov/WDMC-Ex2-Ultra/master/uInitrd
dd if=/dev/zero of=/dev/mtdblock2
dd if=uInitrd of=/dev/mtdblock2

I don't know what is trying to look for in the hard drive to boot, any help will be appreciate it.

Thanks for your time to read my nightmare :)

New chapter, I have had lucky and the box has booted up from a USB key.

So I guess I would be able to flash an modified uImage and uRamdisk to work with the uBoot from the command line, right? But which one could I use?

Thanks,

Do you have a serial bootlog? if serial console still not working then

dmesg
mount
cat /proc/mtd

Why not using the latest Debian rootfs nad kernel on USB?

Why not using the latest Debian rootfs nad kernel on USB?

That would be great!! It's the idea, but I don't know how :)

You are booting with stock kernel and rootfs on NAND. And the envs cannot be listed without serial console. So we cannot adjust the envs to boot USB rootfs. It's a catch-22 :)


Now connect serial console and see if it works. Hit return a few times to see the prompt appear.

It's the first thing I did, to connect the serial cable. But same, nothing is coming :(

So, just to understand, no matter I can compile the kernel, an uImage and a uRamDisk, it won't work, right?

Right, it is quite risky to flash the kernel files to NAND without serial console. You would need to have some way to boot it from RAM or USB first.

However, you mentioned that

How did you do this? are the kernel files on this USB drive? If that how you boot the kernel, then there is a chance that could work.

-bodhi

Yes, the files are in the USB, there are no drives. I've created a folder named boot, and just copy uImage and uRamdisk as follow

/ # ls /mnt/boot
uImage    uRamdisk
/ # ls -l /mnt/boot
-rwxr-xr-x    1 root     0          4177681 Nov  3  2022 uImage
-rwxr-xr-x    1 root     0          2679866 Nov  3  2022 uRamdisk

There files come from here: https://hackers.cx/wdnas/WDMyCloud-Mirror-Gen2/Debian/Dev/

And the way to boot from USB is:

** Put the USB 2.0 in the slot 2
** Press and hold the reset botton, then power it up.
** Release it after 40 seconds.

i5Js ,

Follow the instruction and create the released rootfs Debian-5.13.8-mvebu-tld-1-rootfs-bodhi.tar.bz2 on a different USB drive.

You need to do Step 3 and use armada-385-wd-ex2-ultra.dtb

Quote

3. Create uImage with DTB appended. I am using the Zyxel NAS326 as an example here. Please replace armada-380-zyxel-nas326.dtb below with the appropriate DTB name for your box.

cd /media/sdb1/boot
cp -a zImage-5.13.8-mvebu-tld-1 zImage.fdt
cat dts/armada-380-zyxel-nas326.dtb >> zImage.fdt
mkimage -A arm -O linux -T kernel -C none -a 0x00008000 -e 0x00008000 -n Linux-5.13.8-mvebu-tld-1 -d zImage.fdt uImage

Save your current stock kernel uImage on the VFAT USB that you was booting with.

Quote

/ # ls /mnt/boot
uImage uRamdisk
/ # ls -l /mnt/boot
-rwxr-xr-x 1 root 0 4177681 Nov 3 2022 uImage
-rwxr-xr-x 1 root 0 2679866 Nov 3 2022 uRamdisk

And copy the uImage from the new rootfs over to/mnt/boot, and keep the uRamdisk as is.

With both USB drives in the port, reboot. See if it can boot into Debian.

Ok! many thanks, !'ll do,

Question: can I do it from a Linux VM using crosscompile?

PS: Fingers cross!

i5Js,

No need to cross compile anything. The rootfs creation steps are universal.

-bodhi

Ok!! Thanks

You can also do it in stock OS.

which tar
which mkimage

I shlould restore all the box first, because it’s completely empty, just an usb with two files :)

I’ll try with the VM

Should I rename the uInitrd to uRamDrive ?

> Should I rename the uInitrd to uRamDrive ?

No, the Ramdisk for booting is stock initrd on the FAT USB.

The new rootfs initrd is quite larger than stock, so pretty good chance is that it wont boot.

But if the new kernel+old RamDisk combo does not boot, then try the uInitrd anyway (in this case, yes, copy it to uRamdisk).

-bodhi
===========================
Forum Wiki
bodhi's corner (buy bodhi a beer)

Ok, understood: first try new kernel + oldramdisk second try all new

Let’s see

First try: new kernel + old RamDisk -> doesn't boot. I guess the kernel is ok, because it is the same behaviour: try to boot, with the red led and blue blinking, but the it's off.



Edited 1 time(s). Last edit at 11/04/2022 11:25AM by i5Js.

We are close:

Bonus: new kernel+new Ramdisk, but remain the name as uInitrd -> The box boot it up in safe mode, I can access to the web interface to flash whatever.
Bonus2: new kernel+old Ramdisk, but remain the name as uInitrd -> The box boot it up in safe mode, I can access to the web interface to flash whatever.

I did it, there are two usb drives, USB1 with the old boot, and USB2 with the rootfs created. Unless I didn't understand your step, I've overwritten the USB1 uImage over USB2, letting the uInitrd untouched.

It booted again with the old kernel, as expected. But I can't see a difference.

more info if it helps,

Reading and reading, I think the problem here, perhaps, is the u-boot:

1) Update u-boot. It is needed to adjust load addresess for new Kernel and Ramdisk. See UBoot folder for details.

Checking this:

https://github.com/vzhilov/WDMC-Ex2-Ultra/tree/master/1.UBoot

I have dumped the u-boot and the size is significantly different:

-rwxr-xr-x 1 root 0 5.0M Jan 1 00:03 u-boot.org

vs

-rw-r--r-- 1 root root 933K Nov 4 17:51 u-boot-a38x-GrandTeton_2014T3_PQ-nand-uart.bin
-rw-r--r-- 1 root root 936K Nov 4 17:51 u-boot-a38x-GrandTeton_2014T3_PORQUE-nand.bin

I don't know if I could write it into the nand.

The 2 cases when it boot into WD recovery: because uRamdisk is missing. So the kernel did not start. The recovery web page is from this u-boot.

So basically the same as it was with USB recovery.

The reason it's 5MB vs less than 5MB is: the entire mtd0 is 5MB, actual u-boot is less than 1MB. Just so happens that this rebuilt u-boot is 936K.

It is risky without serial console. Usually we run kwboot to load another u-boot over UART and run it. If it can run then it is a recovery path, even if the new u-boot is bad, or the flashing is bad, we can still recover.

Since serial console works for others, I would spend more time to investigate your serial console problem first.

And then if you decide to flash that u-boot without serial console, you must get vzhilov or CyperPK or others to dump the envs image. And then flash both u-boot image and the envs image in the same session.
