How to unpack the firmware?

Question

linux

The firmware is from a Chinese camera, you need to unpack it, binwalk -Me does not work, the output is a 0.jffs2 file and an empty folder, while 0.jffs2 is not mounted. Link to firmware file

Answer 1

Googled how to mount jffs2. In older versions of Linux, this was done one or two times, in more modern ones it is done through dancing with a tambourine. But it's still possible.
And at the same time look here , maybe it will lead to some thoughts (I didn’t use it myself).

Answer 2

Somehow I also tried to deal with the camera, but the firmware file could not be defeated.
Do you have access to the camera board? There should be a serial port, 4 pins, tx, rx and power with ground. It's easier to connect through it and get access to the console.
Then you can merge fs or some files.
