Hello,

my power plug stopped working while I was trying to flash Kirkwood on my NSA320S. Now all that is lighting up are the blue power-LED and the yellow/green LED next to it and there is nothing on the serial console. I guess it's bricked. Is there still a chance to get it working again?

Thanks

zc5,

Yes. You will need to connect serial console first. Do you have another Linux box and can connect serial console to the NSA320S?

Hi bodhi,

thank you for the fast reply.

The 320S is my only NAS. I have a USB to RS232 converter since my laptop don't have a dedicated serial port.

1. You will need a separate Linux box. So that laptop must be able to run a Linux distro such as Ubuntu, Mint,... If not, you can use a Live Linux DVD/USB disk.


2. USB to RS232 is not appropriate to use. See here for USB TTL serial module adapter:
https://forum.doozan.com/read.php?8,13263,13264#msg-13264

Or you can buy a low cost rPi Zero to use for this purpose (it is easy to connect just the wires to the Pi and the NSA320S).

The NSA320S aready has a serial header. So you can use jumper wires to connect to those header pins. The Cp2102 on eBay that I mentioned in the link, most of them packaged with 3 jumper wires already.

bodhi,

I have a laptop running Linux and a RPi3. I connected TX and RX according to (1) to the pins 8 and 10 on the Pi. For TX and RX i tried the second and the third pin on the 320S, as seen in the second image on (2). According to dmesg ttyAMA0 is connected, but screen /dev/ttyAMA0 does not show any output.

2 http://mud-slide.blogspot.de/2013/12/installing-linux-on-zyxel-nsa-320-part_722.html

=======================

bodhi's Note: Usually, you can use kwboot from your Linux host distribtion (no need to download kwboot). But the latest kwboot has been greatly improved recently and will boot many Marvell Armada SoC boards successfully. See here to download:

https://forum.doozan.com/read.php?3,27280

=======================

First some background. The NSA320S is a different box from the NSA320 (in the 2nd link you posted).

I believe the NSA320S serial header is the same as all these other Zyxel NAS boxes (NSA310S, NSA320, NSA310, NSA325, and NAS326). It looks like this:

+----+----+           
          |    |    |
+----+----+----+----+----+
|3.3V| TX | RX |    | GND|
+----+----+----+    +----+

Now, it is not surprising if you did not see any output, regardless of whether the connection is correct. If power went out during flashing u-boot, or a wrong file was flashed to the box mtd0, then u-boot cannot start when you power up (the image was corrupted), hence nothing will come out of the serial console.

To recover from a bad u-boot flashing, we need 1) serial console connection like you already did. 2) The next step is to use kwboot to load the good uboot image using serial console. As I mentioned in the u-boot release thread:

Quote
https://forum.doozan.com/read.php?3,12381

UART Booting: If possible, try to test this boot image with UART booting before flashing to NAND. See davygravy's UART booting using kwboot instruction here in this thread. The latest u-boot image released here should be used for UART booting, if your box is the type that supports it (these do not: Dockstar, Pogo E02, iConnect).

Basically, you would download the latest u-boot for NSA310S/320S:

Quote
https://forum.doozan.com/read.php?3,12381


uboot.2017.07-tld-1.nsa310s.bodhi.tar
md5
4af9c6f16e1705e7a4345e6f7cc01fa7
sha256
724cb6ac5baf2053e63dc44489693c6772264ca326f4bdb2506c81f654ea84dc

And then from the rPi, instead of running picom/minicom/screen, you would run kwboot (install u-boot-tools if it was not already installed).

The command to run kwboot in rPi is:

kwboot  -t -B 115200 /dev/ttyAMA0 -b uboot.2017.07-tld-1.nsa310s.mtd0.kwb -p

Note: from other Linux rootfs the device would be USB0, so the command can also be:

kwboot  -t -B 115200 /dev/ttyUSB0 -b uboot.2017.07-tld-1.nsa310s.mtd0.kwb  -p

When you see u-boot outputs its banner and the rest of the booting activities, you've unbricked your box!

bodhi,

that was a very easy to follow walkthrough, thank you. I tried it on my RPi first, since my laptop wouldn't run the precompiled kwboot binary. It stopped as soon as the NAS got turned on.

My next attempt was using it from within a docker container and that kind of worked:

./kwboot -t -B 115200 /dev/ttyUSB0 -b uboot.2017.07-tld-1.nsa310s.mtd0.kwb -p

As you see, it tried to boot from kirkwood-pogo_e02.dtb which I don't understand. Maybe I used a wrong image last time?

When trying to boot with a USB stick containing a rootfs (as described in Linux Kernel 4.15.2 Kirkwood package and Debian rootfs) connected it succeeds to enter BusyBox!

I didn't get to see the u-boot bunner, but it booted!

I meant "When trying to run kwboot while a USB is connected to the NAS".

Sorry for posting three times in a row (should have created an account). Using kwboot it now runs Debian. I just misspelled the partition label.

bodhi,

thank you for your great help! After using kwboot to get to Debian, I went through the flash instructions again and this time everything went right. The 320S now boots directly to Debian on the USB drive.

Thank you again!

Hi Bodhi,

I shall post in this topic.

First thank you for prompt reply. I have tried the followings:

0. connect usb cable to serial console of the NSA320s; lsusb shows:
Bus 003 Device 010: ID 067b:2303 Prolific Technology, Inc. PL2303 Serial Port

1. turned on NSA320s by pressing button;

2. run 'kwboot -t -B 115200 /dev/ttyUSB0 -b uboot.2017.07-tld-1.nsa310s.mtd0.kwb -p' command from a Linux laptop.

Sending boot message. Please reboot the target...-^C

and wait but nothing happens ... I had to ^C to return to prompt.

this cable worked before when I have opened the serial console and connect to NSA320s on the same laptop port....

Did you try running serial console before the mtd0 was bricked?

Reverse the steps


1. run 'kwboot -t -B 115200 /dev/ttyUSB0 -b uboot.2017.07-tld-1.nsa310s.mtd0.kwb -p' command from a Linux laptop.

You can take as long as you want before pressing the button.

Yes, it was working (saw uboot messages and I could stop loading further the kernel etc) before mtd0 was corrupted. It should work ...

I followed:

1. run 'kwboot -t -B 115200 /dev/ttyUSB0 -b uboot.2017.07-tld-1.nsa310s.mtd0.kwb -p' command from a Linux laptop.

and then
2. turned on NSA320s by pressing button;

still the same behaviour rolling nothing '/\' like I have seen from others with % sending the kwb ...

I shall try again.

Oooops I haven't realised that I need to continue with booting and reset it again. I am trying again to send kwb to mtd0 ...

Bodhi,

I sent kwb again. boot but I realised the envs are the ones which are looking for rootfs usb disk ...

Bodhi,

When I do rootfs disk do I need to do this step?

4. Create uImage with embedded DTB for booting with older u-boots (2012 or earlier). Do not do this step if you have installed the latest U-Boot for Kirkwood (or are installing this u-boot at the same time).

Please replace kirkwood-goflexnet.dtb below with the correct DTB name for your box (see the folder /media/sdb1/boot/dts for the exact spelling of your Kirkwood box name).

Generate the uImage with DTB embedded inside:
cd /media/sdb1/boot
cp -a zImage-5.2.9-kirkwood-tld-1  zImage.fdt
cat dts/kirkwood-goflexnet.dtb  >> zImage.fdt
mv uImage uImage.orig
mkimage -A arm -O linux -T kernel -C none -a 0x00008000 -e 0x00008000 -n Linux-5.2.9-kirkwood-tld-1 -d zImage.fdt  uImage
sync

Hi Bodhi

Now all sorted as I managed to boot the kernel. The problem was that the two sata disks were on and when I took them out usb disk has been recognized and was used to boot ... no need to make new uImage and uInitrd as the kwb contains everything to boot from the kernel as it is.

Cool! So after you've booted into Debian, you can reflash u-boot quite easily.

Without the sata disks in usb booting works.

Any ideas how to fix usb booting with the two sata disks in? Thank you in advance.

The quickest way to work around the problem is to tell u-boot that you don't want to scan all types of disks

setenv devices usb

Because you are booting with USB rootfs, you can do this and then figure out what cause the "EHCI timed out on TD" error later.

=======


This error was supposedly fixed by ray's patch that I included in U-Boot 2017.07-tld-1. But I guess your HDDs types are another case where the patch did not work. Some old WD and Seagate HDDs are problematic during booting (the SATA driver is not the same one used in the kernel).
