The serial console will provide much more information about the cause of the problem, and some chances to get round it.
However, I still don't know what is the issue or the fix when I am in the console
A transcript of what shows from power-on should help to understand what the underlying problem is.

Then in terms of possible useful commands - interrupt the bootloader and show the output of the 'help' command.

Then in terms of possible useful commands - interrupt the bootloader and show the output of the 'help' command.
Below are outputs from the terminal. I ran as much commands that I think was useful. There is one command, "upf", that similar to update, but I don't know what this mImage file it is looking for.

Thanks again!

Code:
HKVS # help
The following commands are supported:
boot    help    bios    diag
mtest   dump    erase   go
exec    ping    r8      r16

Use 'help' to get help on a specific command

OK, so no flash read/write commands in that bootloader.

I ran as much commands that I think was useful. There is one command, "upf", that similar to update, but I don't know what this mImage file it is looking for.
That can be risky - and is best avoided if you are unsure of the purpose of the commands.
upf is the 'factory update' command. It installs the min-system recovery image and the main firmware.

A transcript of what shows from power-on should help to understand what the underlying problem is.
But it would probably be useful to know what the current problem is.
Can you do a transcript of a normal power-on, with no interruptions?

I have provided 2 different scenarios. One with the network cable plugged in and another without. I checked with WireShark and SADP Tool and don't see any activities from the camera beside the initial tftp check from WireShark.

With the network cable plugged in. I left it on for about 20 minutes and no extra output from the terminal

Without the network cable. I also waited for a while and still nothing on the terminal

I have provided 2 different scenarios. One with the network cable plugged in and another without.
Your transcript suggests the camera is attempting to boot firmware version 5.4.5 Build 170123 and I'd speculate that it had been applied over a very early firmware version such as 5.1.6 that had not created valid data in mtdblock1. This partition holds info on number of reboot times, and whether the previous update was successful or not.
If the counts indicate the last update did not succeed, a reboot is triggered.
But it does not reboot properly into the min-system recovery environment.
That's a 'Catch-22 situation' as the min-system holds the system update code.

A suggestion to try :
With the tftp server running, and a digicap.dav file from an early firmware version such as the 5.2.0 from here :

power on, interrupt the bootloader and try the 'update' command.
Post the full transcript here and we'll see what it says.

I have downloaded 5.2.0 firmware as suggested to my tfpt directory. When I issue the 'update' command, it just stay stuck in that mode. I don't see any activities in the tfpt log or in wireshark. I waited for at least 20 minutes before giving up. .
Code:
HKVS # update
I figured maybe it doesn't have a good image, so I typed 'tftpboot' and see see the camera grabbing the digicap.dav file from my tftp. I waited for about 10-15 minutes to see if it would do anything afterward. It did not, so I typed 'update'. Again this just hang at the terminal and does nothing that I can see.
Code:

BTW, I tried a few different firmwares (5.2.0 and 5.4.41) to see if it would work, but no luck. That is my the file size in my output might be match to what you are expecting. Thanks again.

You've confirmed that the min-system recovery environment, that does the firmware update process, is not working.
It can be possible to work around this and recover the camera, but the process can be a bit messy if you are not used to working at a low level.

Here are a couple of pointers to how this has been done before, should you wish to try them :

I have followed the commands from the 2 posts. I spent most of my time trying to get the mount working. I ended up using this command 'mount -t cifs /192.0.0.128/temp /mnt/nfs00 -o username=myuser,password=mypassword'.

Toward the end, when flashing the mtdblocks, I got a lot of errors. Only one that worked without any errors are on mtdblock11 and mtdblock12.

lot of errors when running cat /mnt/nfs00/mtdblock8 > /dev/mtdblock8
some errors on cat /mnt/nfs00/mtdblock9 > /dev/mtdblock9
errors on cat /mnt/nfs00/mtdblock9 > /dev/mtdblock10
no error on cat /mnt/nfs00/mtdblock11 > /dev/mtdblock11
no error cat /mnt/nfs00/mtdblock11 > /dev/mtdblock12
errors on cat /mnt/nfs00/mtdblock13 > /dev/mtdblock13


I think this device is dead and it's time to get a new one. In the future, it something is working, don't do any firmware update. :)

Outputs of the log, just in case you see something.

Thanks for all your help!

After the reboot, sometimes it goes into mini system and hang there. If I power cycle the camera, it would into busybox but without an ip. If I set the ip, I can ping it but doesn't see anything with SADP or the web interface.

I have followed the commands from the 2 posts. I spent most of my time trying to get the mount working. I ended up using this command 'mount -t cifs /192.0.0.128/temp /mnt/nfs00 -o username=myuser,password=mypassword'.
Yes, that's a good alternate to using NFS when a handy NAS isn't available.

lot of errors when running cat /mnt/nfs00/mtdblock8 > /dev/mtdblock8
That's the partition that holds the min-system recovery environment.

I think this device is dead and it's time to get a new one.
I think you're right.
It seems to be riddled with flash failures, lots of bad blocks.
These would only get worse, and exceed the reserve in the file system to deal with them.
You've had a pretty good go at exploring the problem, and try to deal with it.
But sometimes a fix just isn't possible.

If I set the ip, I can ping it but doesn't see anything with SADP or the web interface.
Yes, those responses would come from the davinci main app if it was running, but the boot-up has been limited to just get to a shell prompt.

Outputs of the log, just in case you see something.
Despite the errors in re-flashing the critical partitions - did you check what happened when the bootargs variable in the bootloader was put back to its original value as opposed to the one that drops the boot-up into a shell prompt?

Alastairstevenson, I got my hikvision cam up and running today!

Today, I have some spare time and thought I would give it another "good old college try". I ran your commands again but it was still giving me a lot of bad block errors. With nothing else to lose, since this camera is a goner, I took a bit more risk and cleared the bad blocks table (don't remember the exact command, but it was under diag). I then went and follow your postings for reflashing the /dev/mtdblocks. To my surprise, I was able to flash mtdblock8 without any errors. The other mtdblocks that gave me errors still doing the same. Upon reboot, I noticed I was no longer stuck at the mini system. From there, I followed the debrick process and got the cam flashed with firmware 5.2.0. It is up and running now, but not with the latest firmware. I can live with 5.2.0 firmware, as I don't want to go thought this mess again.

Let me know how I can buy you some beers for all your help. :thumb: Thank you for all your help again!
