Hello,
There is a DVR equipment in our laboratory which is bought about 4-5 years ago. But somehow there is not any technical detail documents nor source code about this equipment.
We are trying to run it; but it doesn’t work. From serial port output, I see some linux output messages, but it stops during loading. It seems original software is corrupted.
Do you have any idea where I can find some technical documents of this DVR including schematics, software image and source code ?
Please find attached photos of DVR and text file of serial port output messages.
