On the last page we finially got into La Fonera, and now here are some shots of the board itself, seperated from the chassis:
Where that big heatsink is, thats the wireless chipset and the Atheros cpu. Right below the metal shield is the RAM which is marked Hynix HY57V281620ETP-H. Between the metal shielding and the RAM is the solder pads for a 14 pin EJTAG interface. Directly to the right of the RAM is the serial header. I really would like to remove the heatsink and the metal shielding, but the heatsink is soldered on the other side of the board, and I already mentioned the lack of a decent soldering iron. The next pic is of the backside of the board:

Allrighty, not a lot going on here. The chip in the center is a Altima AC101LIQTG. The other chip in the lower right is the 8 MBytes of serial flash. This chip is labeled ST 2SP64V6P. After marveling at the simplicity of the PCB design, I wondered what could be done to hack this little router. So I began to scour the internet. I found a couple places that explained how to get a serial console up on the little router. That is a little too complex for me right now, I don't have the patience nor a good enough soldering iron to do the job(hence the lack of a JTAG tutorial on here). After searching for a bit longer I found a website describing how to use a code injection technique to activate the latent SSH daemon in the la fonera. I was finally getting somewhere.
