SADP now displays a camera. The firmware is no longer 5.1.6 as when originally purchased. See attachment.

I don't mind trying a few more things, as there does seem a glimmer of hope...


Well, that's an interesting result.
It confirms there is a problem with the flash memory of the camera.
But block 69 is into the unused space after the working part of the min-system recovery partition, so that specific failure isn't fatal in this case.


And it has brought the update facility back to life - it's working normally.

However - when the downloaded firmware is being written to the flash memory, there is another write flash failure.
This is in a different location from that used by the min-system recovery area.

So - what to do now, apart from trash the camera?
It depends on whether you want to spend any more time on exploration.

A simple and quick thing to try, though, would be to see what the bootup looks like now.
There is some resilience built in to the partitions needed for normal operation.
The kernel, root file system, application and configuration partitions are all duplicated with a primary and secondary area.
There are basic checks on bootup that switch between primary and secondary.
Try booting normally and see how it looks.

SADP now displays a camera. The firmware is no longer 5.1.6 as when originally purchased.
That's the 'min-system recovery environment', as shown in SADP, now working OK after your nandwrite command use.
It will provide more facilities to do things than the bootloader.
Did the camera boot straight in to it, or did it get there from another startup eg 'start to enter min system'?
Usually the flag that triggers a min-system reboot is automatically reset such that a subsequent boot doesn't try to go there.

There are various possible ways forward, though the problem with the failing flash may get in the way, depending on how widespread it is.
But there is a need to know more about the current status - we (or at least I) don't know what was last stored in the flash memory.
The last update process looked like it aborted.

So - I suggest taking advantage of the running min-system to grab some data that needs checked.
You will need the non-Hikvision tftp server running on the PC.
The PC IP address can be left as normal, no need to disturb it.
Lets assume for this example that the PC IP address is 192.168.1.100 - adjust below as needed.

Using the serial console, set the camera IP address to match the range that your PC is using.
Adjust the IP address to suit. This isn't a permanent change.
First see what is currently in use
ifconfig
Then change as needed, for example :
ifconfig eth0 192.168.1.200

Grab a copy of mtdblock6 and mtdblock1
To run firmware of 5.3.0 or over, the contents need to be correct or the camera will go to a bricked state.
cat /dev/mtd6ro > mtd6ro
tftp -p -l mtd6ro 192.168.1.100
rm mtd6ro
cat /dev/mtd1ro > mtd1ro
tftp -p -l mtd1ro 192.168.1.100
rm mtd1ro

Grab a copy of the app partition, to get an idea of the latest firmware loaded.
cat /dev/mtd13ro > mtd13ro
tftp -p -l mtd13ro 192.168.1.100
rm mtd13ro

If you could zip them up and attach here, I'll take a look at them and see if mtd6 and mtd1 need changes.

The next steps could be directly copying images of the kernel, root file system and app partitions to the camera primary and secondary areas.
How successful that will be depends on whether there are any flash problems in the associated locations.

That's good.
So that's a Chinese DS-2CD2532F-IWS mini-dome, with the brickfixV2 firmware installed, and a valid template in mtdblock1.
mtdblock6 needs the language byte changed and the checksum altered. The modded file is attached.

If you're up for it, we could try writing the needed partitions directly.
What's very likely, from what we've already seen, is to hit some flash failures, which may well mean the device cannot be recovered.
But not all the flash is used, and there is some resilience with the pri and sec copies.
I don't think there is much to lose in trying this, however, it's your choice whether to.

Here are the commands needed, and the files are attached here.
Lets assume the PC running the tftp server is on 192.168.1.100 and you can adjust the values below to suit your actual PC IP address.

Using the serial console, at the min-system shell prompt, set the camera IP address to match the range that your PC is using.

I've been using camera 192.0.0.64 and PC as 192.0.0.128

I do not think there was any errors, but, there is a big but, after I entered 'reboot', it now just keeps rebooting continuously. I stopped it by entering ^U

My worry was should I have stopped it or let it keep rebooting???

That's good.
So that's a Chinese DS-2CD2532F-IWS mini-dome, with the brickfixV2 firmware installed, and a valid template in mtdblock1.
mtdblock6 needs the language byte changed and the checksum altered. The modded file is attached.

If you're up for it, we could try writing the needed partitions directly.
What's very likely, from what we've already seen, is to hit some flash failures, which may well mean the device cannot be recovered.
But not all the flash is used, and there is some resilience with the pri and sec copies.
I don't think there is much to lose in trying this, however, it's your choice whether to.

Here are the commands needed, and the files are attached here.
Lets assume the PC running the tftp server is on 192.168.1.100 and you can adjust the values below to suit your actual PC IP address.

Using the serial console, at the min-system shell prompt, set the camera IP address to match the range that your PC is using.
Adjust the IP address to suit. This isn't a permanent change.
First see what is currently in use
ifconfig
Then change as needed, for example :
ifconfig eth0 192.168.1.200

tftp -g -r mtd6ro_mod 192.168.1.100
cat mtd6ro_mod > /dev/mtdblock6
rm mtd6ro_mod

tftp -g -r mtd9ro 192.168.1.100
cat mtd9ro > /dev/mtdblock9
cat mtd9ro > /dev/mtdblock10
rm mtd9ro

tftp -g -r mtd11ro 192.168.1.100
cat mtd11ro > /dev/mtdblock11
cat mtd11ro > /dev/mtdblock12
rm mtd11ro

tftp -g -r mtd13ro 192.168.1.100
cat mtd13ro > /dev/mtdblock13
cat mtd13ro > /dev/mtdblock14
rm mtd13ro

reboot

I do not think there was any errors,
No, the write of the flash partitions looked good, better than I'd expected.

My worry was should I have stopped it or let it keep rebooting???
Stopping was the correct thing to do.
That last reboot loop was permanent - it's the type of complaint when EN firmware is applied to a CN camera.
Which should not happen with the modded mtdblock6, so the underlying cause will be something else.
It looks like it thinks that the last attempted update failed.
That's a trigger to go into min-system mode.
I wonder if it's complaining due to mtdblock1 contents?

What was interesting was the bad block recovery and format process being done by the UBIFS file system.
That seems to have worked OK.
Then at the end of that it decides that an update has failed.

I think the next step could be a re-write using a donor of an mtdblock1 that has a record of the same version of firmware being successfully applied.
This can be done via the bootloader.

Leave it with me for now while I take a look at that.

OK - can you try this, at the bootloader, in the same way as you managed to recover the min-system environment, using the IP addresses set as required for the PC and the camera.
The needed file is attached.

tftpboot 0xc2000000 mtd1ro_donor
nandwrite 0xc2000000 1 0x100000
reset

And I'm keeping my fingers crossed that this will keep it happy.

starting pid 654, tty '': '-/bin/psh' BusyBox v1.2.1-171136 Protect Shell (psh) Enter 'help' for a list of davinci system commands.
That's better!
'psh' is the 'protected shell', introduced in firmware 5.3.0 and later if I remember correctly, to stop people being able to do 'useful' things at the Linux shell.

The mtd1ro I supplied was a valid template - but as it had not been used over an update process it didn't have a record of successful updates in it.
So the camera firmware determined that the last update was not successful and attempted a reboot into the min-system recovery mode.
My mistake.

I'm speculating (hoping) that the current status of dropping in to the psh shell is because 'init=/bin/sh' is still a parameter in bootargs.
With any luck these next steps will yield a good result.

With the serial console, interrupt the bootloader.
Use printenv to list the current environment variables.
Hopefully bootargs will still include init=/bin/sh - so we need to put it back to how it started with that removed.
You should have a record of the initial settings, it probably looks like this, but check :
bootargs=console=ttyS0 initrd=0xc0a00000,0x400000 rw root=/dev/ram dbg=0
At this point, it would also be a good idea to put the IP address definitions back to normal, so the commands would be :

setenv bootargs console=ttyS0 initrd=0xc0a00000,0x400000 rw root=/dev/ram dbg=0
setenv ipaddr 192.0.0.64
setenv serverip 192.0.0.128
saveenv
reset

And hopefully get a good result.
If so, after bootup has completed, press return a few times to confirm there is a psh '#' prompt, and use the command
prtHardInfo
to see the firmware version and other info.

I'm keeping my fingers crossed!

The init=/bin/sh was removed when you told me to put it back. I did note that my original settings files did not have the dbg=0. Frankly I tried it both ways and result is same. Is this OK??

I do not know where to enter the command prtHardInfo.

That's better!
'psh' is the 'protected shell', introduced in firmware 5.3.0 and later if I remember correctly, to stop people being able to do 'useful' things at the Linux shell.

The mtd1ro I supplied was a valid template - but as it had not been used over an update process it didn't have a record of successful updates in it.
So the camera firmware determined that the last update was not successful and attempted a reboot into the min-system recovery mode.
My mistake.

I'm speculating (hoping) that the current status of dropping in to the psh shell is because 'init=/bin/sh' is still a parameter in bootargs.
With any luck these next steps will yield a good result.

With the serial console, interrupt the bootloader.
Use printenv to list the current environment variables.
Hopefully bootargs will still include init=/bin/sh - so we need to put it back to how it started with that removed.
You should have a record of the initial settings, it probably looks like this, but check :
bootargs=console=ttyS0 initrd=0xc0a00000,0x400000 rw root=/dev/ram dbg=0
At this point, it would also be a good idea to put the IP address definitions back to normal, so the commands would be :

setenv bootargs console=ttyS0 initrd=0xc0a00000,0x400000 rw root=/dev/ram dbg=0
setenv ipaddr 192.0.0.64
setenv serverip 192.0.0.128
saveenv
reset

And hopefully get a good result.
If so, after bootup has completed, press return a few times to confirm there is a psh '#' prompt, and use the command
prtHardInfo
to see the firmware version and other info.

I'm keeping my fingers crossed!

The init=/bin/sh was removed when you told me to put it back.
Oh, OK.
That's a pity then as it would have been the reason that the system boots up to psh but doesn't start up davinci, which is the main app, despite this looking perfectly normal.
starting pid 376, tty '': '/etc/init.d/rcS'
I was really hoping that was still there and if removed it would burst into full life.
But it hasn't, yet.

The command prtHardInfo would normally be used at the '#' prompt at the end of your serial console transcript, but without davinci running it won't give anything useful.

So, there are no errors, but it looks like some of the firmware is missing as it's not started up the main app.
To give some more information, can you try the 'dmesg' command?
There should be quite a lot of info, which should give some clues as to what's going on.

Oh, OK.
That's a pity then as it would have been the reason that the system boots up to psh but doesn't start up davinci, which is the main app, despite this looking perfectly normal.
starting pid 376, tty '': '/etc/init.d/rcS'
I was really hoping that was still there and if removed it would burst into full life.
But it hasn't, yet.

The command prtHardInfo would normally be used at the '#' prompt at the end of your serial console transcript, but without davinci running it won't give anything useful.

So, there are no errors, but it looks like some of the firmware is missing as it's not started up the main app.
To give some more information, can you try the 'dmesg' command?
There should be quite a lot of info, which should give some clues as to what's going on.

OK. Here it is
Well, as far as it goes, that's absolutely fine, normal and no errors.
So the question is - why does it not continue on to do the rest of the startup process where the main application davinci amongst others is started?
We need to take a look at what's in the file system and spot what's missing.

I'm conscious of the fact that you've already spent quite a bit of time with this to-and-fro activity over the forum.
No-one would argue that its a cost-effective way to get back to a working camera - it would be cheaper to just buy new.
But sometimes we do things just for the interest and because we can - with the effort to get to the end-point not much counted.

So, before consuming more of your time on what's arguably a fairly inefficient process of trial and error, I need to ask your views on whether you want to continue?
I'm quite game for it - I quite like the puzzling and learning that is the result.

Frankly, I'm quiet astonished at your enthusiasm to help others. It's truly the exception, not the norm.

I myself had the same thoughts, but it was more directed at the concern that I've already consumed your time more than should be alloted to a forum user...

While I am by no means following what you are doing, but merely being the "inputter" to your thoughts in the hope of resurrecting this camera, I will respect your decision when you feel its time to let this camera go in peace.

I did glance over the results and figured you might comment on these bad blocks. Does this mean anything?

Early on during your help, there was a goal once to execute the "update" command to load digiccap.dav??

I did glance over the results and figured you might comment on these bad blocks. Does this mean anything?
The newer flash memory handles bad blocks in the hardware - but for older hardware some of the file systems handle bad blocks at a software level, as you saw in the UBIFS file system in your serial console transcripts. But not all the partitions are protected by using UBIFS, as you saw from the min-system problem.
From what I've seen, most camera flash doesn't have bad blocks, but some do. It's OK as long as it doesn't 'grow bad blocks' and add more.

Early on during your help, there was a goal once to execute the "update" command to load digiccap.dav??
Yes, this thought has occurred to me, as the min-system facility is back working, the 'update' command (would need the 5.4.5 digicap.dav as that's what's now installed) might do a full refresh of all that's needed.
It would be a bit of an 'all or nothing' approach.

But before that - maybe a couple of things to find out more of what's still not quite right.
There is another trick that's been out in public just a little, that Hikvision have closed off in later versions, that should allow your camera to boot to a full root shell and sidestep psh.

If the current bootargs looks like this
bootargs=console=ttyS0 initrd=0xc0a00000,0x400000 rw root=/dev/ram dbg=0
change it to this, ie add debug single

setenv bootargs console=ttyS0 initrd=0xc0a00000,0x400000 rw root=/dev/ram dbg=9 debug single
saveenv
reset

Then, if a root shell is successfully reached, have a look at the root file system (they are all a lower-case L)

ls -al /etc
ls -al /etc/init.d

Then issue the command to complete the bootup

/etc/init.d/rcS

And I forgot - assuming that /etc/rcS doesn't do all that it should, check the contents of the 'app' folder with

ls -al /dav
ls -al /home

The main file to look for is initrun.sh

And I forgot - assuming that /etc/rcS doesn't do all that it should, check the contents of the 'app' folder with

ls -al /dav
ls -al /home

The main file to look for is initrun.sh

Code:
setenv bootargs console=ttyS0 initrd=0xc0a00000,0x400000 rw root=/dev/ram dbg=9 debug single
I copied this line, but, was wondering should dbg=9???


The newer flash memory handles bad blocks in the hardware - but for older hardware some of the file systems handle bad blocks at a software level, as you saw in the UBIFS file system in your serial console transcripts. But not all the partitions are protected by using UBIFS, as you saw from the min-system problem.
From what I've seen, most camera flash doesn't have bad blocks, but some do. It's OK as long as it doesn't 'grow bad blocks' and add more.


Yes, this thought has occurred to me, as the min-system facility is back working, the 'update' command (would need the 5.4.5 digicap.dav as that's what's now installed) might do a full refresh of all that's needed.
It would be a bit of an 'all or nothing' approach.

But before that - maybe a couple of things to find out more of what's still not quite right.
There is another trick that's been out in public just a little, that Hikvision have closed off in later versions, that should allow your camera to boot to a full root shell and sidestep psh.

If the current bootargs looks like this
bootargs=console=ttyS0 initrd=0xc0a00000,0x400000 rw root=/dev/ram dbg=0
change it to this, ie add debug single

setenv bootargs console=ttyS0 initrd=0xc0a00000,0x400000 rw root=/dev/ram dbg=9 debug single
saveenv
reset

Then, if a root shell is successfully reached, have a look at the root file system (they are all a lower-case L)

ls -al /etc
ls -al /etc/init.d

Then issue the command to complete the bootup

/etc/init.d/rcS

Ok, that's good.
Despite the app partition being mounted, there are no files in it.
/dav is empty.
That's the problem.
dbg=9 gives a lot more detail in the serial console.

I wonder if the secondary partition has files? If so voting then over should fix it.
Let me see what the commands would be for that.

OK - here we go.
At the root shell where you last entered those commands :

mkdir /dav2
/usr/sbin/ubiattach -m 14 -d 2 /dev/ubi_ctrl
/bin/mount -t ubifs /dev/ubi2_0 /dav2
ls -al /dav2

And if that last command lists a couple of dozen files, they can be copied over to the primary partition -

cp /dav2/* /dav
/bin/umount /dav2
/usr/sbin/ubidetach /dev/ubi_ctrl -d 2

reboot
