1) Built in ttl console

I have built in a ttl to usb adapter for direct access with usb printer cable (check photos in url)

ttl port speed: 115200

pinout
black = ground
grey = rx
white = tx
(rx and tx might be interchanged, all depends on your ttl module)

setenv usb_load_uinitrd 'ext2load usb $(device) 0x1100000 /boot/uInitrd'
setenv usb_boot 'run usb_load_uimage; run usb_load_uinitrd; bootm 0x800000 0x1100000'
setenv set_bootargs_usb 'setenv bootargs console=ttyS0,115200 root=/dev/sda1  rootdelay=10  rootfstype=ext3'

Please post your dmesg output after booting and logged in as root with serial console.

Also see this thread: Debian Linux on Zyxel NSA320S (success)

It might or might not be because you're booting with the NSA320 DTB. chrlee has a new DTS for NSA320S which I'm going to include in the next kernel release to see if it will be enough.

Hello and thanks for getting back to me

hope this type of topic is ok, i plan on keeping it up to date

Theres something about the RJ45 port on my box.... sometimes the light comes up sometimes it does not but i believe that makes me fail and so everything else fails

very nice blog that is but pitty is in hungarian, need to do some google translate

i will keep you posted

EDIT:

This is wery weird network card on NSA320s runs on 10mbit for some reason, its port 18, not sur why it worn claim full speed, also it wont obtain ip from dhcp nor will release the static one which does not work either

Also gbit link comes up when i load up the standard zyxel image, but i can not access or ping it, looks like the network is gone on the board, i have ordered a USB > LAN adapter maybe ill have more luck with that

EDIT 2:
I have attached dmesg output

EDIT 3:
with a lot of probing and testing between 3 routers and switches finally gbit network came up, not sure how but im updating it now vai apt-get update
