Hi,
I've come across some Logilink wl0038 routers. It's quite cheap to get, but it seems it won't be able to get openwrt on it as of now?
There was some GPL statement sent with it, so I started to experiment with it a bit.
- CPU is Realtek 8186
- 2M Flash (Spansion chip)
- 8M RAM (Hynix chip)
- Serial port (header J1, down right), works (see below)
- J2 seems to be a JTAG port (2x6 pin, lower line seems to be GND)
If anyone's interested I have photos.
I've checked the J1 header to go to the UART1 of the RTL8186. Pin layout (Pins of the CPU - btw, maybe the serial signals are mixed, so RTS/CTS and TXD/RXD could be swapped). These have TTL signal, I've put them to a MAX232 level converter:
1 - Vcc
2 - GND
3 - CTS (Pin 80)
4 - RTS (Pin 73)
5 - RXD (Pin 79)
6 - TXD (Pin 58)
I've connected GND, TX/RX, set hyperterm to 38400,8,N,1, and got the console output of it:

I've already requested the source code, let's see what happens.
But is there anything happening on the RTL ports? Haven't seen anything useful?
(edit: put in better boot messages, hyperterm obviously mangles the scrollback ...)
