wrt54g serial port pin out.

With nothing better to do at almost 1am, and because I had already written up something on my [tag]Fonera[/tag], I decided I’d post the pin out information, for my usb to serial adapter on my [tag]wrt54g[/tag].

I bricked my router a couple days ago, when I flashed the wrong device in CFE. Smooth eh? Well I’ll write up something when I get the [tag]j-tag[/tag] adapter and patience to fix it. For now here is the pin out for my setup serial port. I soldered on the j-tag pins when I put on the serial port a few months ago. I don’t remember why I used different pin types.

La Fonera serial port pinout.

I finally figured out the pinout of my la Fonera in relationship to my USB serial adapter. Now I can use RedBoot to unbrick my fonera. The connection is a bit wonky, and works 95% of the time. I have to make the serial connection before turning on the Fonera.

From the power connector.
Pin 1, Pin 2, Pin 3, Pin 4
GND, Tx, Rx, VCC
Red, Black, White, No Connection.

You should also be able to change the serial configuration by using the RedBoot command fconfig caution as you can make your Fonera not automatically boot if you change the boot script. Thanks to shadowyandy for this tid bit of information.
