Hi, can anyone help me? I am trying to get my Dahua SD22204T-GN-W camera to boot up by updating the firmware via TFTP. I have run the run commands but camera still will not boot up. The U-Boot screen shows the below. Can anyone tell me how to fix the fail to load bootargs part. Thanks U-Boot 2010.06-svn5163 (Jan 16 2018 - 05:03:02) I2C: ready DRAM: 110 MiB gBootLogPtr:00b80008.

Hi, can anyone help me with this problem i have? In the image i have attached there is a faint horizontal static line going through the image. I have changed the BNC cable but that did not fix this issue. The camera is a Dahua HAC-HDBW2221RP-Z. This camera has a motorised zoom and when i use the zoom, the camera seems to turn off and back on. Not sure if these both issues are linked. Any help to solve this issue would be greatly appreciated.

Hi, thanks for replying. My thoughts were power supply. I have tried 3 different 12v 2a power supplies but same problem every time. The length of cable is 30m, Annke brand. I have ordered a 12v 4a PSU to try.
