Helllo,

I have Zyxel NBG5615 router. Can I install OpenWrt on it ? I didn't find any information about support for this model.

I made pictures of router inside.
There are on PCB:

CPU:
Ralink RT6856F - Wi-Fi SoC contains a powerful 700 MHz MIPS® 34KEc™ CPU core and two PCI Express interfaces

Memory:
Winbond W971GG6JB-25 - 1G bits DDR2 SDRAM - DDR2 800 (5-5-5)

Flash memory:
Macronix MX25L12845EMI-10G - EEPROM 128Mb - 128Mx1 - 104MHz - cmos mxsmio serial multi i/o flash memory - 2,7-3,6V

Other:
Realtek  RTL8367RB - high-performance 5+2-port Gigabit Ethernet switch
Ralink RT5392L - WiFi chip
RT3593L - 802.11 a/b/g/n 3T3R PCI Express Single Chip
3x SiGe SE5003L: 5 GHz, 23dBm Power Amplifier with Power Detector
JTAG pins and serial port (terminal).

What should be next step, connecting to the terminal (serial port on PCB) with cable? how to read EEPROM with firmware for backup ?

I'm interested also in buying this router,do you know if it has 128 or 256 mb ram ? I f you look inside ,it has one or two module Winbond W971GG6JB-25 ?
Thank you!

There is only one WBGA chip so it's 128 RAM version.

Ok,thanks for your answer.I asked because on http://wikidevi.com/wiki/ZyXEL_NBG5615  it says 256mb...
Best Regards!
