The NC1000-W10 is a wireless camera made by some random company in China and OEMed by a number of companies.
The firmware that comes on the controller appears to be a standard build from the OEM with just the logo JPG changed to whatever company is selling it. There are two main worker programs, camera.flat and mctest, for which the source code is not currently available.
The main focus of making a free firmware bundle would be to rewrite these programs. camera.flat provides the web server, camera interfaces, and audio streaming.
I have built some firmware bundles for testing that add useful features:
The firmware bundle read by the software has a 20 byte header followed by a Linux kernel in a ZIP file and then the ROMFS image.
Some software you try to build won't work. You might need to add these to the Makefile or the command line when compiling:
CFLAGS="-D__PIC__ --fpic -msingle-pic-base" LDFLAGS="-Wl,-elf2flt=\"-z\""
The board has a 2x10 header on it right next to the W90N740 processor. It has JTAG and serial port connections to it. Note that the VCC connection is +5V and the TTL logic is 3.3V, so you can't use the VCC pin for a TTL-to-RS232 converter.
