WL-500g Premium died After Upgrading Firmware

[Oleg]

Have you tried pin9 trick again?

Have you tried pin9 trick again?

Oleg--

Thanks for your reply. Yes, i've tried the pin9 trick again, to no avail.

I found schematics for a rs232/uart converter, but am not 100% sure this is what I need.

Have you worked with the uart/serial interface much?

yes, i've 2 serial cables made of nokia phone cables...

Hmmm..
Does the board natively support rs232?

If not what all is required?

From what I was reading, it would require a rs232 chip (which i have), as well as a uart chip of some sort. is this correct? Or was this for a previos version of the wl500?

The instructions here (http://www.dd-wrt.com/wiki/index.php/User_talk:Oxo) are quite cryptic.... would you mind clarifying? Maybe i understand...if UART2 an external uart chip in the circuit that he built, and he is using UART1 on the circuit board, and not using UART0 at all. That would make sense...

Ok, the connector is soldered on, so now we need to check software.

* start for example minicom and connect to ...UART2
* check that there is no echo of characters
* connect UART2 tx to rx
* check that there IS echo of characters
* connect UART2 tx to UART1 rx and UART2 rx to UART1 tx
* try and connect to prompt...

If a uart and max232 chip are required, how did you build these into the nokia cable with a power supply/voltage regulator?

Thank you very much, Oleg!! I am hoping to learn a little something doing this... have done some circutry, but not much. As well as hopefully find that my wl-500 is not totally bricked

you do not need uart for the wl500g premium.
the thing you need is level shifter, which usually built using max 3232 or max232 ic.

just search for any wrt54g tutorial - it's exactly the same (except the board pin out).

Thank you again, Oleg.

I will look into it later tonight

take care..

On the circuit board there is a silkscreen showing the spot for a header that has uart0 and uart1 tx and rx, as well as ground, 3.3v reference, and something labled 'reset' (i believe).

Oleg-- if you're listening-- Do you use that 3.3 volt feed as your supply for the rs232 chip? I assume yes.....

Hope this helps.. I will be trying to find the right capacitors for the max232 chip today after work, or at least find the spec sheet for the ones I have...

take care

Is somewhere described the pinout of the UART in WL500gp ?

Thx, ric.
