I opened up my GN-B41G and took a few high resolution photos of the circuit board.
Top side, MiniPCI removed
(MAC and serial numbers intentionally blanked out)
There is a sticker on the flash memory. The part# under the sticker it looks like Am29LV160D. That's 2MBytes.
The SDRAM is on a 32bit databus and is 16MBytes in size.
I would love alternative firmware support for this router. IPv6 support would be really nice.
I'am a programmer and a hardware engineer working full time developing TCP/IP and other protocol stacks for embedded systems, but unfortunately my linux experience is very limited.
There is a 20pin header on the board. Looks like a standard pinout 20pin JTAG header to me. JTAG ICE debug support will of course help any development efforts.
The unmounted connector (CON1) could be a serial port, but from the looks of things I'd say it is more likely a alternative power connector. It could of course be a combined serial port / power connector.
