With the Samsung smart TV use-case, these web cameras relied upon the Samsung TV uploading the firmware to the camera's RAM each time it is connected.
Why?????
-
This way they only need RAM on the device and can get rid of the need for persistent storage/flash memory. Makes a much simpler board design and easier manufacturing with less costs for parts.
So efficient!! C-Level and shareholders love that!!

Probably so the camera could be updated on the fly and not be brickable via a random power cycle. Still seems stupid though.
-
If it seems stupid, that just means that it was cheaper to do it this way.
Program ROM/EEPROM + RAM, or just RAM connected to a USB interface with a reset line tied to the camera processor? See the USB device ID connect , fill the ram with the camera software, toggle processor reset , off you go.
