Hi,

I did start the project, designing the pcb in Eagle and when I decided to order the components, I did some mathematics and found out that it would get way cheaper and less troublesome to buy a evaluation kit from FTDI.

So after receiving the kit I started by disassembling the router, found the serial connector and after some wiring trial and error I got the serial to work.
The following is the serial console log.

Code:
LZMA 4.05

Quantum v1.01
Allocatable memory starts @ 0x53b900, end @ 0x1000000
No, or invalid, configuration information in EEPROM - trying FLASH

<NOTASK>: WARNING - output to NULL stream (is IO library initialized?)
No, or invalid, configuration information in FLASH
Invalid configuration information

No wonder the router was bricked, the firmware running is for the DR834 vpn router.
I'm in the process of checking commands and what they do, but I didn't find anything useful for flashing the router with the correct firmware.

If anyone as something on how to flash firmware with this type of router feel free to post,
Best regards, saphex.
