Tell me, if anyone came across, where to dig to unpack the firmware of the Dongjia DJ-GK2839S camera? The following is known about the camera:
Kernel: Linux 3.4.43-gk armv6l
File system: 28-ONVIF V1.0.0.0 build 2016-07-22 11:16:08
Web Control Version: IPCConfig V2.0.0.52 Firmware
file (firmware_GOKE -7101-V1-APP-V1.0.0.0_20160722111615.bin) looks like this when viewed by binwalk:
DECIMAL HEXADECIMAL DESCRIPTION
----------------------- -------------------------------------------------- -------
71844 0x118A4 xz compressed data
128840 0x1F748 xz compressed data
218740 0x35674 xz compressed data
... and so on until the very end
binwalk -e -M gives a set of little meaningful bits of xml, elf and other files mixed inside and among themselves. Those. no hints of u-boot, uImage, cramfs, cpio, etc., which I expected to see - no at all.
It looks like I'm misunderstanding something, or not taking into account ...
