Problem with NSA310S

Hi,
I was trying to install u-boot using this guide: http://forum.doozan.com/read.php?3,12381. Everything was fine until I rebooted the device. Suddenly the upper LED started to blinking in red colour and it was the end. I cannot log in via telnet/ssh.

Is there any way to fix that?

Do you have a log of what you did during installation? serial console log?

grab a USB-TTL (or UART) adapter, (like this http://www.instructables.com/id/Usb-to-SerialTTL-adapter/ there are tons of them selling for cheap on ebay or similar, the windows driver has to be downloaded from the chip manufacturer usually) connect it to the box's serial debug port (see here for your device) http://zyxel.nas-central.org/wiki/Serial_port_%28NSA310s%29

And then you can see what the uboot is saying on the serial console when you power on the device, change settings to get it to boot, and even load a new uboot over the serial connection in case you managed to brick the box (see here http://forum.doozan.com/read.php?3,7852,7852 ).

bobafetthotmail,

It is flashing red so it is highy likely recoverable without serial console. Yes, but it is certainly easier with one, though.

Well I dont have a log file. Or maybe there is a way to check the terminal history in linux?(I'm using terminator and arch linux distro)
Will the pl2303hx uart be good?

Maybe netconsole, if it is setup correctly. I always tend to go for the surest way to fix things tho, too many times I wasted hours for nothing.

Besides, I've seen he disassembled his NAS already in the pics he posted, that means something. :)

ok, I finally got this uart chip.
I found somewhere on the Internet that the scheme for connecting this thing is as follows:

+----+----+----+ +----+
|3.3V| TX | RX | | GND|
+----+----+----+ +----+
Source: http://forum.nas-central.org/viewtopic.php?f=249&t=16733

So I plugged it like that:

Am I right?

ok, I read that I should connect TX and RX inversely.
I've got this output now:

What should I do now?

So your u-boot image was written sucessfully. You probably missed the step of flashing u-boot default envs image, or the steps about setting them further).

Try again. Monitor the serial console, let it boot all the way, don't interrupt it. Copy the entire serial log (from the u-boot banner to the last line when it stopped) and post here (or pastebin it).

This is all:

Well at this point I dont know what to do.
I have a pendrive with Debian-4.4.0-kirkwood-tld-1-rootfs-bodhi.tar.bz2 which was working before I updated uboot. Is there a way to boot it? Or should I try flashing from the serial console?

EDIT1: My pendrive is visible: http://pastebin.com/WxXAbiZg Is there a way to boot it?

yast,

Follow instruction in this thread 1st post and create a new 4.4.0 rootfs using USB:
http://forum.doozan.com/read.php?2,12096

Updated 20 Feb 2016:

This Debian-4.4.0-kirkwood-tld-1-rootfs-bodhi.tar.bz2 is to keep in sync with kernel Linux-4.4.0-kirkwood-tld-1.

Boot with it. If there is problem booting, capture entire serial conosole log and post here.

I changed environment variables using "setenv" in serial console

Now debian is booting but it is getting kernel panic:

The LED is blinking green now.

EDIT1: http://pastebin.com/CuB61VUw My environment variables
