netsrac 0 Posted January 21, 2015 Hi, I was playing around with my HikVision camera an accidentally saved a large file into /tmp which is amounted ram disk. While the system was unresponsive, I rebooted it. It was running in a loop. I could ping the IP address for a while but it looked like the system is running into a reboot loop. So no exactly sure what happened, but now it's not responding to any pings again. So it looked like I bricked my HikVision 2032 camera. I already tried to run the TFTP Server and let it re-install the firmware. But this did not work. I can't even see something trying to open a connection to the tftp server. I also run wireshark to see if there are any connects from the camera...but nothing I can notice. Also the IR LEDs stay off all the time. So I opened up the camera to look for a serial port. There is a connector called JP1 which has a cable going to the front of the camera. Does anyone know if and where the Camera has it's serial console port connector? Any other ideas how to de-brick the camera? Thanks, Netsrac Share this post Link to post Share on other sites
iTuneDVR 2 Posted January 21, 2015 TFTP log? Make screensot! Share this post Link to post Share on other sites
netsrac 0 Posted January 21, 2015 TFTP log?Make screensot! The tftp server says nothing....no connection from the camera...and as I wrote, I also used wireshark to look onto the network. I can see the tftp server on 192.0.0.128 advertising itself every once in a while, but no request from 192.0.0.64. I also tried resetting the camera or turn on the camera with the reset button pressed....nothing.... Share this post Link to post Share on other sites
iTuneDVR 2 Posted January 21, 2015 It's mean that no access to port 69 on your PC. Check your firewall. How many LAN on your PC? Share this post Link to post Share on other sites
netsrac 0 Posted January 21, 2015 PC has two LANs, but I selected the right one. I try a "tftp / connect 192.0.0.128 /get digicap.dav" from a linux box that runs on the same network and that works fine...so I'm a bit confused why it's not working... Share this post Link to post Share on other sites

I mean your WAN connection. Share this post Link to post Share on other sites
buellwinkle 0 Posted January 21, 2015 I haven't looked at that model that closely, but does that model have a RS232 port on the circuit board? You may be able to use that to connect at the boot loader level to see what's happening. Share this post Link to post Share on other sites
iTuneDVR 2 Posted January 21, 2015 Use TTL2RS232 adapter if your DVR yet no signs of life Share this post Link to post Share on other sites
netsrac 0 Posted January 22, 2015 No signs of live via UART for now...but my FTDI adapter is a 5V version - guess I need a 3.3V version... Share this post Link to post Share on other sites
