DHI-NVR5432-16P-4KS2 won't boot up after upgrade

Dear Alexis, sorry for my late reply but I have been researching more before I talk to you again.

Understand my situation please....

I have a Dahua NVR5216-16P-4KS2. I think it is based on a Linux-3.10.0_hi3536 (Hilsilicon)

I have tried a lot of methods for TFTP upgrade but I am doing something wrong. Either I do not have the correct IPs for the TFTP serevr or I do not have the right TFTP/NVR upgrade files.

Please find attached a photo of what Putty gives me when connecting with a console cable.

Thanks a lot Alexis for your help

Hi Davidson,
Stange. On mine i can t see enter key to stop autorun but not on your.
You have not exactly thé same 5432 for me.
You can try to enter key * many Time at the boot Time, you must have prompt with #
So you should pass command run ....

Let me know

Regards
 
Hi Alexis

Yes I managed to stop boot loop with * enter but it look like I have the TFTP server or IP setting wrong ? and which file do I put in the TFTP server ?

See picture

During thé boot dis you see thé link on the nvr ethernet port? If yes you can test Ping nvr ip -t on the pc to know if thé nvr have the défault ip 192.168.1.108

Nooo :(

If I fix that part I think we can fix my issue,

I am using Cisco TFTP and I tried using Hikivsion TFTP server too. I can see putty response with NVR but TFTP server I am not sure how it works :(

My NVR had a static IP address before the upgrade corrupted, does the NVR have default IP now ?

First
You must be connected to nvr with serial câble. 115200 8/N/1.
Keep key * puch untel you have thé prompt with #
So you will be able to pass comand for exemple help and enter.

Try pléase and let you know

OK
So you're suggesting to connect to NVR via RS232 (COM) PORT on the and use putty to send command right?
I need to find the COM Cable and Computer with COM Port

If you do not have a computer with a COM port you can use a USB to serial cable.

It worked with my laptop via USB and NVR

It has to be the exact type which I attached in this message :)

Can always help :)
