To test the new kernel,I think it's better to add a serial port to the box.After disassemble the it,i find 4 holes in the circuit board,but the voltage between rxd and gnd and txd and gnd is 0v,what wrong with it?

OK I got the serial port working now. Here's how.

Look at the first two pics in http://www.yamasita.jp/linkstation/2008 ... ole_1.html

You have to use 2 strands of wire to connect those 2 pair of pins marked as red and blue.
Then connect your serial cable to CN19 connector, the white dot on the top side mark the pin 1.
connect pin 1 to Tx , pin 2 to Rx (or vice versa, I can't tell for sure :p ) and pin 4 to GND

The serial should be working now. Good luck. :idea:

Hello... Has anyone been able to get a serial monitor working on a LS-CH1.0TL? I have circuit board MVKKT-CA, and as it has a blue web interface, so it's a V1. I have been trying to replace the 1TB drive with a 2TB drive, and been unable to do so until now.

I tried to DD the entire drive - no cigar :? (partitions look very different). I've also tried to format the new drive in the same way as the old one and DD the individual partitions - also no cigar. :? I also got the EM mode working (major undertaking!!) and when trying to format the 2TB drive, I get the dreaded APC_STATE_FAILURE message from LSUpdater.exe. :o I am very familiar with uboot (Sheevaplug and other systems) so I thought it would be a good idea to see what's going on during the boot process. The LED that blinks 6 times is not too useful in trying to understand what's going on.

Have you tried to use the TFTP-way ?
First, get the right version of firmware (you will brick
the box, if you try to flash a firmware of the V2 model,
if you REALLY have a V1 model; be warned!).
Then, remove all partitions from the new disk before
putting into the box.
The run the TFTP procedure.
DO NOT restart the box.
Start the correct firmware updater in debug mode and
let the updater partition the disk.
Rerun the TFTP procedure but this time, do NOT partition
the disk.
According to several posts, this should make it work.

Yes have. Wtih TFTP I can see it loads the kernel and the initrd. As I mentioned in my previous post, the format does not work - it results in the dreaded APC_STATE_FAILURE message when running LSUpdater.exe.

That's the reason, why you should then repeat the
TFTP procedure WITHOUT repartitioning.
Unfortunately the Buffalo software is more a hack
than a stable release.

Well, I have read the various entries and tried this with partitions, without partitions, etc. I wasted over 24 hours on this thing.
Thanks for the hints in any case. I think I need to attach wires to the serial to see WTF is happening.

According to the records here in the forum, it is important to start
with a completely empty disk (no partitions).
The first TFTP -> LSUpdater try will fail with ACP_STATE_FAILURE.
One guess for this is, that the timeout is too short and LSUpdater
"thinks" the partitioning/formatting failed, but instead it is still
running.
Maybe you have to wait a while, before restarting the box and doing
the TFTP stuff again?
