my pc ands server ip 192.168.31.141
default gateway is 192.168.31.1
im defining xvr as 192.168.31.201
xvr connected router via cable
laptop connected same router via wifi
 
I have a SD22404T-GN that is not accessible. With wireshark i see that it's advertising on the network but the easy Tftp solution is not working.

I have ordered a usb ttl dongle so i can try the uart solution.

1 part of the instructions is not clear for me.
do i need to connect all pins to the camera? so VCC, GND, TX, RX or only RX and TX?
 
Thanks, Will do that.

As soon as the adapter is in i will give it a go again (no luck with a RPi, but that could be a linux noob thing ;-) )
 
Please help,
three SD22404T-GN cameras suddenly stopped working, looks like they stuck in boot loop.
I connected CP210X dongle and tried to restore firmware, but it does not allow me to stop the autoboot and im not able to type anything.
any suggestions. tnx

The camera does this again and again.

i took the eeprom out and flashed it with a programmer out of good camera still its doing this loop

I don't know if I took the the right firmware I'm not sure,

Since I've updatet I coudn't do any changes in the configuration.
The Cam does a reboot then.
It does also a reboot every 5 to 10 minutes.
So far I've confiigures a serial connection with a ft232rl usb to seriel conector and aftr many tries I got a connection.
I changed ip address and run a tftp server and could load files down but I got this message

[ERR0002:]The img header be changed!
I've googeled the message and found this:
Dahua IPC EASY unbricking / recovery over TFTP
I think the problem is that the new firmware installed a new bootloader that doesn't allow firmwaredowngrades.
Please tell me how do I et the older firmware to my cam
Click to expand...

To anyone that get the error message "[ERR0002:]The img header be changed!" the problem is that you have to flash first the kernel.img otherwise the camera will ignore anything you put in the commands.txt

Here is my commands.txt for the IPC-HDBW5231E-Z

"tftp 0x82000000 kernel.img; flwrite tftp 0x82000000 romfs-x.squashfs.img; flwrite tftp 0x82000000 web-x.squashfs.img; flwrite tftp 0x82000000 .FLASHING_DONE_STOP_TFTP_NOW sleep 5"
the latest files you need are inside the fw zip file with name DH_IPC-HX5X3X-Rhea_MultiLang_PN_Stream3_V2.800.0000029.0.R.221220.zip
 
good day! I have a dh-ipc-hdw2231 camera.
I connected to it but I can't download the firmware. the commands described at the beginning are not suitable, and the output of "printenv" has a different appearance

Hello everyone, maybe someone could shed some light on my problem. I have a Dahua SD49225T-HN-S2 PTZ camera that stopped working from one day to the next, has entered a reboot loop and has returned to the factory IP 192.168.1.108 Unfortunately I can't fix it through TFTP It keeps rebooting and the connection cannot be established. I want to find the UART port of the camera but I can't find it. I've only found these single pins that seem to be the UART port but I can't get them to connect since nothing appears on the monitor when the power is connected to the camera Is there a way to activate the UART port?

on usb adapter i conected tx with rx (on camera), rx on usb adapter with tx(on camera) gnd usb to gnd camera, vcc 3.3v usb to vcc 3.3v on camera.
Once you conected all that ( before there is two white conector 4(whires) to disable ptz check on camera boot (so it doesn`t start spinning and disabling your conection usb to camera)..
I will post later those pictures where those conectors are...

when you disconect pin to disable ptz movement conect rx,tx,gnd,vcc3.3v to usb adapter, open putty baud rate 115200, flow control to none. Putty window will open and then conect the camera to power supply - turn it on...

you will se uboot loader then press and hold * (on keyboard)....

All of this is fine for me, but there is no network connection from camera to my computer...i conected camera directly to my computer or switch. There is always a same problem no conection...

Should i connect camera with poe+ network switch and hope there will be a network conection on my computer
Click to expand...

I have a Dahua SD49225T-HN ptz camera that stopped working overnight. I want to find the UART port and I see in your photographs that it is similar to the pins on your camera, but when I connect the ubs-ttl to it, nothing appears on it. monitor. My question is, what voltages do the Rx and TX pins of your camera have?
 
I have a SD1A203T-GN that went unresponsive and is stuck in the boot cycle. I have set up the tftp server and the camera will connect to it and it seems like the files transfer and flash? I tried with the multiple commands with no success.

I also tried with the run up command since one of the firmware's had the update.img file.



I think the camera was on version DH_SD-Mao-Rhea_MultiLang_PN_Stream3_IVS_V2.800.0000000.4.R.191105

I have attached the output from the console any help would be greatly appreciated.

Hi have a good day
I have serial port connection and eliminate bootargs to have only linux boot,l want to search directories. But:
1-the date and time reset to 1970-1-1 and time to 0
2-it starts auto commands ...cpu is alive
3-after 3 minutes reboots again!
So I can't type and search anything!
How could I stop this?

Stop u-boot.

Looks like appauto = 0
So, shell without loading modules is normal & watchdog work correct.

Thank you very much, I'll try it.
But what about this string? It's repeating every 10 seconds:
"some numbers...date time cpu is alive"
How can I stop it?
Thanks
