Hello everyone, I have a Hikvision DS-KH8520-WTE1 model Video Intercom Indoor Station. When the device is powered on, it stays at the boot screen. I connected via USB Serial, connected the LAN cable, I downloaded TFTP and firmware, changed the ip address to 192.0.0.128. When I try to install the firmware with PuTTY, I get an error. I cannot get the ip address 192.0.0.64 before the ip address is configured as 192.0.0.128. The ip address appears as 169.254.15.118.

Error message in PuTTY:
Code: 
Please input ip address of device: 192.0.0.64
Please input ip address of upgrade server: 192.0.0.128
Confirm?(y/n): y
DMA reset timeout
digicap update failure

Because sometimes windows can be buggy, work around is you change ip address when you are connected to LAN and then RUN putty or secureCRT, unplug cable and connect to indoor station, that way you will remain on 192.0.0.128
 
Yea well your indoor havent booted yet, and link havent initialize so you wont be able to ping, answer to your question is in my post up, seems like you havent read it , or you did not understood at all.
 
I think I did what you said but the result is still the same.

The procedure I did:
1. I changed the IP Address to 192.0.0.128.
2. I connected to PuTTY via USB Serial.
3. I gave power to the device
4. PuTTY U-Boot is activated when the device is powered on.
5. IP address of device: 192.0.0.64
6. IP address of upgrade server: 192.0.0.128
7. Result failed (DMA reset timeout and digicap update failure)

try flashing with 2.1.24, and you can always connect monitor to same LAN and not use 192.0.0.64 and 128 but actual subnet IP addresses
 
I tried what you said, the result is still the same

Code: 
Now press [u/U] key to upgrade software: u
File system error,please upgrade by TFTP

when prompted to upgrade y/n type b and enter, you will gain public shell. Type help, what do you see

DMA usually stands for direct memory access, maybe we can reset it

From your log i can see one problem. You havent change ip address of your pc. You need to set ipv4 in network adapter. You are still on DHCP

1710088265882.png
 
set ip on for example 1.10

when prompted to set device ip set 192.168.1.9
when prompted to set server ip set 192.168.1.10
then update
 
ServerIP needs to match your PC ip address and using 169.254 is not a valid ip, thats a DHCP default address when there is no DHCP server available
