I have a d-link DSL-3680, which I believe is a provider branded version of the DSL-2680 (Based on the identical specification, and similar release date). I attempted to flash it with the unbranded firmware (and that's why...)
I've populated the serial header on the PCB.
JP1 pinout, 3.3V serial 115,200baud 8N1 [x] : TX [x] : GND [x] : VCC 3.3V [ ] [x] : RX
If I boot the router then I get the following on the serial:
Bootbase Version: VTC_SPI_4M1.25 | 2012/6/8 16:30:00 RAM: Size = 16384 Kbytes Found SPI Flash 4MiB MX25L3205D(06E) at 0xbfc00000
If I boot the router, while holding down the reset button, I get the following:
RT63365 at Mon Oct 31 08:19:49 UTC 2011 version 0.8 Memory size 16MB HWCONF=00005d00 DRAM Mode=00000000 MCC1=00000000 Search PHY addr and found PHY addr=0 done
I can't get anything else from the router, it won't reply to keyed input either. Can anyone suggest if it's recoverable, and if so what can I try next?
