DS411j with strange behavior, and no network

DS411j with strange behavior, and no network
September 07, 2023 03:54AM
Hi All,


I have this unit that is behaving strangely.

Short:
it boots, it beeps as it shout but it does not work.

Long:
I have console access to the unit and can see that it loads kernel and gets to the login prompt but the network is not available.
It may or may not be the only problem.

the goal is to seek advice and try to get to the bottom of the issue, if possible repair the unit.

I have read about and played a little with uboot, tried to load kernels but am not sure if I do it correctly.
I have some soldering skills and a programmer if that is required to revive the flash.
I have linux and windows computers to troubleshoot with.

The problem is that I dont fully understand the booting process, environmental variable and the sections of flash to be able to resolve this on my own.


What have I done so far:
Have tried to load another kernel/rd but not sure did it correctly as it often didnt boot or booted with missing rd message.
[   44.080000] RAMDISK: Couldn't find valid RAM disk image starting at 0.
...
[   44.160000] No filesystem could mount root, tried:  ext3 ext2 ext4
[   44.160000] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(9,0)

bootcmd=bootm F8080000 F8280000
bootargs=console=ttyS0,115200 ip=off initrd=0x00800040,4M root=/dev/md0 rw syno_hw_version=DS411jv10 ihd_num=4 netif_num=1

Where is ramdisk location for this device as it seems to me that it changes on different kernel or is it statically located in flash?
but why will it not boot when i load it manually?


I have tried change the ip-parameter to bootp and can see the nas getting an ip when kernel loads but it disappears when login prompt is shown.
when removing all other kernel paramenters besides the ip=bootp it loads to the point of halt but ip works.

conclusion, the NIC is working fine but the boot process or maybe another part of hardware is faulty?

What can I do from here?

see attachments for console output,thanks

As I can see in the log original-kernel-boot.txt, there is no other problem in booting except for the ethernet failed to get an IP address.

To trouble shoot this, you should not have to play with the way the box is booting. Just log in through serial console when you see the login prompt. And run
ifconfig -a
It's likely to show there is no IP address. And then you'd go from there to look at the log, try something to bring the network up/down, for example,
ifdown eth0
ifup eth0

And so on...

======

Here is a possible explanation why the IP was not assigned.

cat: can't open '/proc/sys/kernel/syno_skip_vender_mac_interfaces': No such file or directory
[  137.250000] eth0: stopped

:: Starting scemd

For whatever reason, the MAC address has changed. So it is likely that the router has refused to assign a dynamic IP address for this box, until a predetermined period. There are some routers that behave like this.

One way to see it is to login to the router page and find out if the old MAC address is still in its database, and clear it.

The other way is to wait a while (perhaps 1-2 hours) and then login to the 411j using serial console, and then restart the NIC, hopefully the router will accept the new MAC address.
ifdown eth0
ifup eth0

======

By the way, this box has been supported in mainline Linux. So you can potentially install and run Debian on it.

Hi Bodhi,

I Appreciate the time you invest in this,

my problem is that I dont have login to the system so I cant troubleshoot from inside the system.

regarding the router/ip, the router is fine and is assiged ip when I changed the nic's "IP"-parametre for kernel.
when booting another kernel the ip is i need pingable but as boot is halted due to ram-disk or whetever other reason the system is not functioning.
this is seen in "change-bootp-and-number-of-nics.txt"


If we'd go back to the login; is there a default user/password depending on unit/kernel used?
is there a way to reset it somehow?

What if one tried to boot another kernel/rd correctly to check the boot process, as mentioned I dont really see where the rd/kernel should be located.

what actually happens when we load the kernel/rd from tftp? do the temporaly go in the ram?
If I would test another kernel/rd, what would be the correct address space to load these to and how is that determined is what Im actually dont completely understand.

bootcmd=bootm F8080000 F8280000
is this same as 0x80000 and 0x280000 and one should always load to these adresses like this, regardless of kernel/rd versions?
tftpboot 0x80000 zImage
tftpboot 0x280000 rd.bin


What is this initrd-parameter then?
bootargs=console=ttyS0,115200 ip=off initrd=0x00800040,4M root=/dev/md0 rw syno_hw_version=DS411jv10 ihd_num=4 netif_num=1

Thanks

dmb4312,

Sorry I cannot be of much help with stock FW. I usually skip stock FW and modify u-boot envs to install latest Linux and Debian. Unless I need to find some info, I never really use stock FW.

You might be able to find the credential at some Synology forum.

Yes.

For Kirwood boxes, see this for typical load addresses for a modern kernel such as one I release here.

This stock FW boot directly from SPI flash, because they can. But usually we load the kernel files to RAM, using commands such as tftp, ext2load,... And then run bootm using the addresses in RAM.

Stock kernel might have been built with unconventional load addresses, too. So keep that in mind.

After trying several combinations of kernel options and kernels, the results are for most the same,
ERROR: flashInfoFill - Failed to get Device Base address and Size (spi_flash 0)
or
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
I gave up the idea to run the stock kernel and followed the guide to boot the 5.13.6 kernel you made, on stock uboot without success.

1.
prepared the USB as per tutorial:
Quote

Updated 26 Sept 2021:
Download at Dropbox:

Debian-5.13.6-kirkwood-tld-1-rootfs-bodhi.tar.bz2 (Bitly short link, use this if you can)

Installation can be done on any Linux box, with a fresh USB drive (SD card or HDD would work fine too).

Note: all steps below must be done while logging in as root user (not sudo). If you are not the root user then don't continue, because the rootfs will not work.

1. Format a new USB drive with a single Ext3 partition, and label it rootfs. If you are running the latest U-Boot for Kirkwood then you can use Ext4. But be aware that Ext4 file system format needs to be "finalized" before it can be used for booting.

2. Mount the drive on a Linux box. cd to top level directory and extract it. It is assuming the USB drive is mounted at /media/sdb1
cd /media/sdb1
tar -xjf Debian-5.13.6-kirkwood-tld-1-rootfs-bodhi.tar.bz2

3. Adjust fstab (optional).

Edit /media/sdb1/etc/fstab entry for root device to match the rootfstype of your rootfstype if you use Ext4 or Ext2. However, you can keep it as is without problem in booting since the kernel will figure out which file system the rootfs was formatted.

LABEL=rootfs / ext3 noatime,errors=remount-ro 0 1

4. (Stock u-boot only) Create uImage with embedded DTB for booting with older u-boots (2012 or earlier). Skip this step if you have installed the latest U-Boot for Kirkwood (or are installing this u-boot at the same time, or running kwboot with latest u-boot image).

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-5.13.6-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-5.13.6-kirkwood-tld-1 -d zImage.fdt uImage
sync

If your Linux box does not have mkimage, then install it

apt-get install u-boot-tools

5. Done.

2.
tried to boot the nas after setting the variables with boot command but the command is missing, i only have bootm command which will not do much:
Quote

Boot Kirkwood rootfs with stock u-boot

Note: I've updated this instruction to make it more robust (to take into consideration the limitation of much older stock u-boots)

Assuming you have created a USB rootfs following the instruction in the release thread.

Power up, interrupt u-boot count down, and then.

setenv usb_set_bootargs 'setenv bootargs console=ttyS0,115200 root=LABEL=rootfs rootdelay=10 earlyprintk=serial'
setenv load_uimage 'ext2load usb 0:1 0x800000 /boot/uImage'
setenv load_uinitrd 'ext2load usb 0:1 0x2100000 /boot/uInitrd'
setenv usb_boot 'mw 0x800000 0 1; run load_uimage; run load_uinitrd; bootm 0x800000 0x2100000'
setenv usb_bootcmd 'run usb_set_bootargs; run usb_boot'
setenv bootcmd 'usb reset; run usb_bootcmd; usb stop; reset'
And then,
printenv
boot

OK so this u-boot does not have auto boot command. So instead of "boot", try running it directly.

run bootcmd

I don't think this there is a new u-boot for this box. I did not build one for it and it's not in mainline u-boot.

dmb4312,

OK so this stock u-boot does not have boot, run, saveenv, and ext2load commands. The only way that you can boot with the USB rootfs is using tftp to load the kernel and then use bootm to boot.

So I need to revise this post to add more instruction about tftp.

https://forum.doozan.com/read.php?2,102054,105374#msg-105374

1. The problem is we don't have new u-boot for it. So to run Debian, you will need to boot this box with stock u-boot, and enter the commands in serial console, but you can not save the envs. It should run Debian this way. But it isn't a complete solution, because it is not automatic booting.

2. There is no close match for this box among the existing new Kirkwood u-boots. You might be able to run kwboot using the GoFlex Home image (uboot.2017.07-tld-1.goflexhome.mtd0.kwb). But there might be problem with the last SATA slot like Billy is seeing in this DS413j thread.

So you if you want to proceed with number 1 above, then I'll add the tftp instruction.

Bodhi,
Thanks for the clarification.
Please do add the instructions for tftpboot, Id like to know if it at all boots at it should.
I assume others would probably benefit of this also.

I will then try second option and see if the box would work automatically with 3 drives, if it does then I'll call it a win.

any tests you'd like me to do I will be happy to help.

Bodhi,

it was successful booting your kernel, wow!
I will test the system as it is before I proceed with uboot testing.

many thanks for your work and the help you give to the community!!
Re: DS411j with strange behavior, and no network
September 11, 2023 01:58PM
I think I understand why the nas didnt work correctly.

your kernel and the stock one cant seem to find onboard NIC.

I attached an USB adapter ran dhclient [nic-name] and the interface came up fine.

As mentioned earlier the nic works fine in uboot and another synology kernel(which otherwise does not boot)

I guess there are missing NIC modules in both kernels.

Most probably not that reason. But we'll see more info after you tried again with the correction below.

Here something you need to correct first. During rootf creation, you've missed the bold part .

Quote

4. (Stock u-boot only) Create uImage with embedded DTB for booting with older u-boots (2012 or earlier). Skip this step if you have installed the latest U-Boot for Kirkwood (or are installing this u-boot at the same time, or running kwboot with latest u-boot image).

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-5.13.6-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-5.13.6-kirkwood-tld-1 -d zImage.fdt uImage
sync

So currently you are booting with the GoFlex Net DTB.

You need to repeat Step 4 with the 411j DTB.

cat dts/kirkwood-ds411j.dtb >> zImage.fdt

Let's make sure you repeat the entire Step 4. The zImage must be the original to start with.

cd /boot
cp -a zImage-5.13.6-kirkwood-tld-1  zImage.fdt
cat dts/kirkwood-ds411j.dtb  >> zImage.fdt
mv uImage uImage.orig
mkimage -A arm -O linux -T kernel -C none -a 0x00008000 -e 0x00008000 -n Linux-5.13.6-kirkwood-tld-1 -d zImage.fdt  uImage
sync

And after booting into Debian, log in and run:

ifconfig -a
ethtool eth0

Please post the entire serial console boot log here (including u-boot banner and all commands you execute at serial console).

Bodhi,
and you were right,
I redid the whole process with usb to be sure and the networking is working as intended.

Appreciate the help and the patience. :)

Yes, that what I was trying to, to use your lastest dtb, was that not how you'd want it?
